About

I am a professor and a director of one of the National Primate Research Centers in the US. My research focus in industry and academics has been on the development of vaccines and biological therapeutics, primarily antibodies. For more than 35 years I have studied various aspects of the HIV Envelope glycoprotein, from structure-function analyses to protein expression, to immunogenicity studies. My laboratory has worked on vaccines in primate models for AIDS that are modeled after native Envelopes from subjects who develop neutralizing antibodies in 2-3 years after infection. For the last 20 years, our focus has been passive studies with broadly neutralizing antibodies to limit mother to child transmission. The lab is currently am working on passive antibody-based approaches to treat SARS-CoV-2 early in infection. In my role as a center director, I enjoy learning from my colleagues here and at other centers so that we can model and understand immune responses and disease pathogenesis. I am an advocate for science education and transparency.

The mechanism of this depletion is not understood, as only a small fraction of all CD4 + cells appear to be productively infected with HIV-1 in seropositive individuals. In the present study, crosslinking of bound gp120 on human CD4 + T cells followed by signaling through the T cell receptor for antigen was found to result in activation-dependent cell death by a form of cell suicide termed apoptosis, or programmed cell death. The data indicate that even picomolar concentrations of gp120 prime T cells for activationinduced cell death, suggesting a mechanism for CD4 + T cell depletion in acquired immune deficiency syndrome (AIDS), particularly in the face of concurrent infection and antigenic challenge with other organisms. These results also provide an explanation for the enhancement of infection by certain antibodies against HIV, and for the paradox that HIV appears to cause AIDS after the onset of antiviral immunity.

1997 (June 01) - BizJournals.com : "Biotech veteran Nowinski touts AIDS-vaccine effort : Amid skepticism, millions sought for VaxGen trials"

Source : [HW0079][GDrive]

Also mentioned : Dr. Robert Charles Nowinski (born 1945) / Dr. Lawrence A. Corey (born 1947) / Dr. Nancy Logan Haigwood (born 1951) / Dr. Robert Charles Gallo (born 1937)

While President Clinton promotes a goal of developing an AIDS vaccine in 10 years, a company led by Seattle biotechnology entrepreneur [Dr. Robert Charles Nowinski (born 1945)] is raising tens of millions of dollars to finance immediate, large-scale testing of just such a potential vaccine.

Nowinski and stockbroker George Steiner of Prudential Securities' Seattle office are recruiting private investors for [VaxGen, Incorporated], which plans final clinical trials in 7,500 American volunteers and another 3,000 in Thailand.

The South San Francisco, Calif.-based company already has raised at least $18 million and hoped to reach $36.75 million, according to papers filed in March with the state Securities Division. Steiner said last week that VaxGen is "very close" to completing its money hunt, but he declined further comment.

Some experts are skeptical of the VaxGen effort, however, saying that the company's so-called gp120 vaccine has been superseded by newer approaches more likely to protect against AIDS.

The National Institutes of Health decided in 1994 not to fund phase-three clinical trials of VaxGen's vaccine, which was developed by biotech powerhouse Genentech Inc.

Genentech itself, after putting $50 million and eight years into its AIDS vaccine, cut its financial exposure in December 1995 by spinning off the research-and-development program as VaxGen. Genentech is contributing to VaxGen 300,000 units of the vaccine but only $2 million in cash.

VaxGen executives, who did not return phone calls, reckon that even a partial preventative to AIDS would be welcome.

The company's private placement prospectus, obtained from a potential investor, says the Food and Drug Administration might even approve a vaccine that protects 30 percent of recipients against AIDS.

Such a vaccine could be given to health-care professionals, law-enforcement personnel and others who face on-the-job exposure to HIV, the document says.

Clinton's declaration this month of a 10-year push to find an AIDS vaccine received a lukewarm reception, in part because it provided no new funding. And AIDS researcher [Dr. Robert Charles Gallo (born 1937)], a co-discoverer of the HIV virus, told reporters the vaccine might indefinitely elude medicine's grasp: "It is possible that we may never develop a vaccine for HIV."

Nowinski himself is controversial in the biotechnology industry. He founded [Genetic Systems Corporation], Icos Corp. and PathoGenesis Corp., all in the Seattle area, and private investors in those companies' large start-up financings generally have profited.

But his launch-'em-and-leave-'em approach has drawn criticism that Nowinski is more interested in starting companies than shepherding them through to success.

Gp120 vaccines have advanced the furthest in human testing. But the shortcomings uncovered in those tests have led many researchers to conclude gp120 alone won't conquer AIDS.

"I hope that gp120 is at least partially effective -- it could be. However, I think we're better off to spend our money to develop vaccines that produce a broader immunity," said Nancy Haigwood, a virologist now at Seattle Biomedical Research Institute, who previously worked at [Chiron Corporation] developing that company's version of a gp120 vaccine.

Although gp120 does cause a significant immune response, she said, "we already know from safety trials that it's not completely efficacious, because (some) people who have been vaccinated with the Genentech product and the very similar Chiron product during safety trials became infected."

For many researchers, said Haigwood, "Life has definitely moved beyond the subunit gp120."

AIDSVAX, the vaccine championed by Nowinski's company, is termed a subunit gp120 vaccine because it uses a portion of the virus's glycoprotein coat with a molecular weight of 120,000.

According to the VaxGen prospectus being circulated in Seattle, the vaccine has been tested in chimpanzees, where it prevented infection from direct intravenous injection of HIV.

In addition, safety tests on 1,093 human volunteers showed no serious side effects, and almost all of them developed high levels of antibody against HIV. Such antibodies have been shown in laboratory tests -- outside the body -- to neutralize HIV, the prospectus states.

But the prospectus also acknowledges that among a high-risk group of 102 vaccine recipients, six did become HIV-infected during the three-year monitoring period.

The document blames that "breakthrough" effect on the existence of different strains of HIV, and says the clinical trials will include mixtures of vaccine variants aimed at different HIV mutations.

Haigwood said the gp120 vaccine's immune effect in chimpanzees has little predictive value. Both the [Chiron Corporation] and Genentech products did protect chimpanzees, but "we already know that it doesn't" work in humans to the same degree, she Haigwood.

One setback to the gp120 vaccine came in December when University of North Carolina researchers halted a test of Genentech's gp120 vaccine in patients already infected with HIV. They stopped halfway through the intended three-year trial after finding the vaccine didn't slow the disease's progress.

However, that failure as a therapeutic vaccine doesn't necessarily reflect on gp120's usefulness as a preventative.

Observers raise another issue as well. Antibodies attack the form of the HIV virus that appears outside the cell, but another type of immune response, called CTL, apparently is needed to attack HIV once it burrows inside normal human cells to begin replicating.

"Both modes of transmission must be addressed for a vaccine to be effective," said a recent status report on HIV vaccines by Drs. Matt Meldorf and [Dr. Lawrence A. Corey (born 1947)], both affiliated with the federally funded AIDS Vaccine Evaluation Unit run by the University of Washington and the [Fred Hutchinson Cancer Research Center].

Various trials of gp120 vaccines "have rarely elicited" that second type of response, according to the report.

Alternative approaches to creating immunity to HIV are in the early stages of testing. "There are some products that do appear to provide a broader immune response, and a more robust response," said Haigwood.

The AIDS Vaccine Evaluation Unit's recent report listed 13 candidate HIV vaccines, among them four gp120 vaccines.

Among the more promising prospects, according to the report, are those that pack a double punch, combining a subunit vaccine like gp120 with a vaccine based on HIV viral DNA spliced into another virus.

If gp120 turns out to produce some partial immunity in humans, it could be part of some future package of several vaccines, said Haigwood. "That I would support," she said.

AIDS. A weariness descends at the sound of the acronym. The working surmise is that heterosexuality, monogamy, safe sex, no drugs, no streetwalkers, no Thai or sub-Saharan trysts are all the average citizen needs to know. Yes, 16,000 a day join the ranks of the infected. Yes, 20 million have died. Yes, 13 million have been orphaned. But death has little purchase, no matter its numbers, when the dead are despised or distant. Even those with compunctions about the responsibilities of superpower citizenship quaver at the tall wall of science to be scaled before informed judgments on AIDS can be made. We know something about an amazing but not curative cocktail of drugs that makes a longer, better life with AIDS possible. We might know such drugs are a luxury reserved for the First World. We might know their efficacy is not always consistent. Still, scientists somewhere will solve this one. Leave the science to them.

But as Patricia Thomas's Big Shot demonstrates, science needs an engaged and knowledgeable citizenry to defeat AIDS, because the best tactic is a vaccine, and after 10 years of hunting, science has failed to find one. The scientific search drew in Congress, the military, the National Institutes of Health (NIH), multinational drug companies, lawyers, biotech startups, academic laboratories, President Bill Clinton and the media. All helped, and harmed, in ways peculiar to them and to AIDS.

With a command of the science and a sensitive approach, Thomas takes the concerned citizen through it all, without hyperbole or shrillness. Congress listened to a powerful lobbyist, slipping money for his client's vaccine into the budget, which caused a scandal, which left Capitol Hill over-cautious on future vaccine funding. The military bogged down in infighting, so vaccine trials were delayed for years. NIH was great at making committees, but the committees were lousy at making decisions; hence none of the 13 most promising vaccine candidates got the NIH support needed for the risky but necessary human trials to be conducted. Drug companies, made to make profits, devoted resources to developing drugs taken daily for years rather than a cheap vaccine taken once. Lawyers advised against human trials -- if a vaccine failed and people died, the lawsuits could bankrupt a company. Biotech startups, small and independent, weren't set up to share discoveries or agree on standards, plus they depended on NIH or the military or big drug companies to put their potential vaccines through massive human trials -- which the big guys failed to do. Academic researchers were hobbled by their culture's embedded snobbery against the human-trial empiricists. President Clinton called for an AIDS campaign in late 1996 after listening to a presentation about this stumbling mess but never followed through. The media partially understood most of it and, by not going deeper, helped sink good ideas.

Thomas's account can be compared with a book published earlier this year on this complicated subject: the smart and authoritative Shots in the Dark by Jon Cohen, a writer for Science. Expecting to spend a year chronicling how a vaccine was discovered, Cohen spent 10, a demoralizing extension that could have buried a lesser writer. Thomas began her book in 1997. She covers the same facts as Cohen but employs some of the conveniences of compelling characters, dramatic scenes and suspense to help you get through the brain-numbing science. Cohen is more analytical, and he comes to a conclusion, advocating a March of Dimes approach to developing an AIDS vaccine similar to the strategy that finally wiped out polio. Thomas makes no overt recommendation, but in the way it is told her book reveals one fairly clearly.

She looks at the vaccine hunt through the eyes of the young scientists who first became obsessed with it back in 1982 and stuck with it for almost 20 years. She refrains from idealizing their initial motives: "Although it would be romantic to think that scientists throw themselves at a new infectious scourge because it vexes their curiosity or stirs pity and terror in their hearts, that isn't how it works." These virologists and molecular biologists "tackle problems that they believe they are equipped to solve."

By the '90s, all they had -- heart, intellect, wits, career, life -- were engaged in the effort. Thomas's implied argument is that such encompassing commitment had everything to do with the little progress made in the last decade on finding a vaccine. There is [Dr. Phillip Wayne Berman (born 1948)], then 34, ordered by biotech management not to work on an AIDS vaccine but who "in his free time at Genentech worked on a vaccine anyway." There is Kathy Steimer, 34, a virologist prone to depression who "was surrounded by men who never lost sleep wondering whether they were wrong about anything," and who still won respect by her meticulous work and willingness to disclose flaws in her version of the vaccine. There is Nancy Haigwood, 31, a molecular biologist whose vaccine was ridiculed for years as "weird science" or "cold fusion." Thomas is great on the forces and individuals -- policy makers, investors, CEOs -- that intentionally and unintentionally thwarted these scientists. Her portrait of NIH's Tony Fauci is damning yet sympathetic. She astutely calls him "a productive narcissist," showing him strutting but sensitive, brilliant but feeble. The chapters on the summer of 1994 that feature him and bring all the hopeful vaccine scientists together are dramatic. We can't help concluding that that summer Fauci crushed the vaccine hunt for years.

This is cheating, of course -- we should be able to read about important issues without these kinds of novelistic tricks. But the science in this tale is so demanding, the types of vaccines being developed so critical to describe, along with the many groups of scientists working on them, that even Thomas's book is difficult, at least in parts. But a third of the way in, you are conversant -- almost proud of it, too -- with all the details, and Thomas's account truly takes off.

Because her book appeared later than Cohen's, Thomas ends with more hopeful news about vaccine trials pushed through because of the mad-dog determination of a retrovirologist biotech entrepreneur named Robert Nowinski and a veteran vaccinologist, Donald Francis. "Tightly wound" and possessing "a mouth like an Uzi," the passionate Francis played important roles in testing vaccines for smallpox and hepatitis B. Results of the massive vaccine trials by their company, VaxGen, are at least a year off, and Thomas is not so unsubtle as to suggest that Francis and Nowinski's heroics will win the day. But anyone trying to understand this issue knows after reading her book that a kind of driven, brilliant passion is what the AIDS fight needs. *

Abstract

HIV-1 neutralizing antibodies are directed to the Envelope glycoprotein trimer on the surface of the virion and block entry into target cells in vitro. During infection, closely related but distinct variants arise in infected individuals, and the interplay of Envelope and neutralizing antibodies is a dynamic process. Vaccines that generate neutralizing antibodies and drugs that inhibit entry must address the issue of variation of subtypes worldwide. The purpose of this review is to summarize major advances in the neutralizing antibody field published during 2005 and early 2006. The main themes that are covered in this review include new findings in the development of neutralizing antibodies during natural and experimental infection, characterization of monoclonal antibodies with neutralizing activity, Envelope structural data, the development of novel Envelope constructs, and novel approaches designed to generate neutralizing antibodies by vaccination. Advances leading to a better understanding of the structure of the Envelope and the character of neutralizing antibodies that develop during the course of infection have provided important clues to guide the design of better immunogens and drugs to block attachment. These findings have implications for prophylactic and therapeutic vaccine approaches, drugs, and antibody-based therapies to reduce HIV transmission.

Summary

Antibodies have a long history in antiviral therapy, but until recently, they have not been actively pursued for HIV-1 due to modest potency and breadth of early human monoclonal antibodies (MAbs) and perceived insurmountable technical, financial, and logistical hurdles. Recent advances in the identification and characterization of MAbs with the ability to potently neutralize diverse HIV-1 isolates have reinvigorated discussion and testing of these products in humans, since new broadly neutralizing MAbs (bnMAbs) are more likely to be effective against worldwide strains of HIV-1. In animal models, there is abundant evidence that bnMAbs can block infection in a dose-dependent manner, and the more potent bnMAbs will allow clinical testing at infusion doses that are practically achievable. Moreover, recent advances in antibody engineering are providing further improvements in MAb potency, breadth, and half-life. This review summarizes the current state of the field of bnMAb protection in animal models as well as a review of variables that are critical for antiviral activity. Several bnMAbs are currently in clinical testing, and we offer perspectives on their use as pre-exposure prophylaxis (PrEP), potential benefits beyond sterilizing immunity, and a discussion of future approaches to engineer novel molecules.

Abstract

Passively administered broadly neutralizing antibodies (bNAbs) targeting the HIV-1 envelope glycoprotein (Env) have been shown to protect non-human primates (NHPs) against chimeric simian-human immunodeficiency virus (SHIV) infection. With data from multiple non-human primate SHIV challenge studies that used single bNAbs, we conducted a meta-analysis to examine the relationship between predicted serum 50% neutralization titer (ID50) against the challenge virus and infection outcome. In a logistic model that adjusts for bNAb epitopes and challenge viruses, serum ID50 had a highly significant effect on infection risk (p < 0.001). The estimated ID50 to achieve 50%, 75%, and 95% protection was 91 (95% confidence interval [CI]: 55, 153), 219 (117, 410), and 685 (319, 1471), respectively. This analysis indicates that serum neutralizing titer against the relevant virus is a key parameter of protection and that protection from acquisition by a single bNAb might require substantial levels of neutralization at the time of exposure.

Keywords: SHIV challenge; broad neutralizing antibodies; correlates of protection; meta-analysis; non-human primate studies.

Nancy Dobbins 'Nan' Haigwood

May 2, 1926 - Nov. 7, 2019

The family of Nan Haigwood is sad to announce that she passed away Thursday, Nov. 7, 2019, after a short illness.

Nan was a native of Yadkinville, N.C., who graduated from the University of North Carolina at Greensboro, which at the time was called "Woman's College" of the University of North Carolina. She excelled in her field of home economics and was a superb mother and wife to her daughter, Nancy and her husband, Paul B. Haigwood, Colonel, USMC (retired). Paul's career took the family to New York (General Electric), where Nan taught first grade and went to diction school at the request of the school--to lose her southern accent, which she did. He then rejoined the U.S. Marine Corps, which led to many new homes in Wrightsville Beach, N.C., Camp Pendleton and Oceanside in Southern California, Quantico and Annandale, Virginia, Bangkok, Thailand, El Toro and Santa Ana, California, Camp Lejeune, North Carolina, Newport, Rhode Island, and Raleigh, N.C. Nan volunteered for many organizations, and she also taught school in Bangkok at the International School of Bangkok (1963-1965). When Paul joined the executive team as Executive Secretary at AMF in New York, they lived in Stamford and New Canaan and traveled extensively in Europe playing golf, touring museums and enjoying many of the world's treasures. They retired to Alamo, Calif., to be close to the grandchildren.

After Paul's death in 1992, Nan followed her daughter to Seattle (1992-2007), helping to raise her grandsons, Nathan, Ben and Aiden Scandella and teaching them to love golf, gardening and Star Trek reruns and the importance of art, literature and travel to other cultures. She traveled to Italy, Spain and the United Kingdom to visit art and gardens. Nan moved again in 2007 to Portland, where she established many new friendships at Claremont and more recently at Terwilliger Plaza. When Nancy married Andy McNiece in 2008, Nan gained another grandson, Kelly, along with his extended family.

She earned her private pilot's license and was an avid sailor on the New River while at Camp Lejeune, N.C. Thanks to two years in Bangkok, Thailand, she spoke Thai and loved and collected, all things Asian. She had an outstanding golf game, was actively engaged with news, art, music and literature and immensely enjoyed her role as a cook and hostess. Nan loved her family and her friends, especially those who so greatly enriched her final years while she lived at Terwilliger Plaza.

She is survived by her sisters, Ruth and Grace; her brother, Charles and their families; her daughter and son-in-law and; her four grandsons. She maintained especially close ties with her sister, Ruth and with the Brookshire arm of the family, nieces Ann and Jane and great nephew Jeff and his family.

Those who are inclined to remember her in some way are encouraged to donate to the Portland Japanese Garden, the Lan Su Chinese Garden, the Portland Art Museum, the Audubon Society, or to buy a book at Powell's, read it, talk about it, and pass it on. A celebration of life will be held at Terwilliger Plaza early in the New Year.

Curtis E.A. Karnow, Stephen C. Lewis, Landels Ripley & Diamond, San Francisco, CA, for Abbott Laboratories.
OPINIONPATEL, District Judge.
Plaintiff Chiron Corporation ("Chiron") brought this action against defendant Abbott Laboratories ("Abbott"), alleging infringement of U.S. Patent No. 5,156,949 ("'949 patent"), which pertains to an immunoassay test for the HIV virus. In its answer, Abbott alleges as two of its defenses inequitable conduct and prior invention. Now before the court are cross-motions for summary judgment on these two defenses.
Having considered the parties' arguments and submissions, and for the reasons set forth below, the court enters the following memorandum and order.[1]
BACKGROUND[2]After the first documented cases of what is now commonly called Acquired Immune Deficiency Syndrome ("AIDS") occurred in the United States in 1981, researchers identified the Human Immunodeficiency Virus ("HIV") as its primary cause.[3] Antibody tests called "immunoassays" were developed thereafter, in order to detect the presence of antibodies to HIV in human blood and thus serve as a means of determining whether the blood is infected with the virus. This action arises out of the development and patenting of these immunoassays.
A. General Background on HIVHIV is a virus,[4] and like other viruses it consists of genetic material and proteins, in the form of a string of nucleotides. Genetic material is the blueprint for all proteins and polypeptides (which are either full or partial *1107 proteins). Genetic material comes in two types: DNA and RNA. A gene is a set of nucleotides that contains the blueprint for a specific protein.
HIV's genetic material is RNA. Although HIV's RNA contains an entire blueprint for HIV, HIV lacks the ability to reproduce by itself. Thus, HIV must use the genetic material of a host cell (such as a human white blood cell) to reproduce itself. HIV enters the host cell, releases its RNA, and makes a DNA copy of its RNA. This DNA copy is then incorporated into and becomes part of the genetic material of the host cell, which begins to make copies of the HIV virus, spreading the infection and often killing the host cell.
When the human immune system detects the presence of HIV, it responds with HIV antibodies and defensive cells. Antibodies are unique molecules formed by the immune system in response to infection, and HIV-specific antibodies are formed as part of the immune system's defensive efforts. These antibodies bind to the HIV virus, and the presence of these antibodies in a human blood sample indicates a current or prior encounter with the HIV virus or part of the virus.
B. Development of an HIV ImmunoassayImmunoassays can be used to detect viral antibodies, and an HIV immunoassay thus can detect the presence of HIV in human blood. Detection is made possible by the reaction or binding that occurs between viral peptides and virus-specific antibodies, a process known as "immunoreactivity." The immunoassays used to detect HIV can be constructed with either natural polypeptides or recombinant polypeptides. An HIV immunoassay using natural polypeptides can be constructed by growing live, fully intact HIV in large quantities, breaking the HIV into pieces, collecting the proteins, sticking them to a surface, and then washing blood over the surface. If HIV antibodies are present in the blood, they bind to the proteins and remain attached to them when the blood is washed from the surface. To detect the HIV antibodies bound to the HIV proteins, enzymes that change color or fluorescent markers that emit light can be used to attach to the antibodies.
The problem with a natural polypeptide immunoassay is that it requires growing large amounts of live, intact HIV, which exposes workers to risk of infection and requires expensive laboratory facilities. Thus, as research began in 1984 on creating an HIV immunoassay, scientists sought to use recombinant DNA technology to make proteins and partial proteins from HIV's outer layer, called the envelope ("env"). Because scientists suspected that the env was immunoreactive, the focus in 1984 was to identify DNA fragments that encoded env polypeptides. In late Spring 1984, a number of teams were fast at work trying to develop such a test, including projects at Chiron, DuPont, and a collaborative project between the National Institutes of Health ("NIH") and Centocor ("NIH/Centocor"). All three teams attempted to create an env based recombinant DNA immunoassay.
To make an artificial env protein or polypeptide, large quantities of HIV genetic material are required. This material can be obtained by copying or cloning HIV's genetic material and making many DNA copies. As scientists decipher the genetic material, they display it on maps showing where genes are located in relation to one another in the material. In order to locate the env region of HIV, scientists from both the NIH and Chiron studied maps of other viruses that they believed would be structurally similar to HIV. Based on study of those viruses, the scientists determined that the genes for HIV's env likely would be in the right half of HIV's genetic material, and began looking for it there.
To locate and isolate particular regions of genetic material, scientists make "restriction maps" by cutting DNA into progressively shorter fragments through a series of reagents called "restriction enzymes." Restriction maps divide DNA into fragments that can be described and defined by "restriction sites." The restriction enzymes recognize specific sequences of nucleotides and cut genetic material at those sites. Different restriction enzymes recognize different sites, a *1108 capability that makes it possible to isolate specific regions of genetic material accurately and repeatedly. Restriction sites are included on the restriction maps of the genetic material. While restriction maps enable scientists to identify and "cut" specific fragments of DNA, "sequencing" is more precise, and enables scientists to create a complete map of the exact order of the nucleotides comprising the DNA.
Between June 1984 and September 1984, the NIH ran sequencing reactions designed to map the nucleotide sequence of an HIV-clone called BH-8. The NIH collaborated with DuPont, Centocor, and Dana-Farber to map the nucleotide sequence of HIV DNA fragments in BH-8, as well as two other HIV clones, BH-10 and BH-5. DuPont received clone BH-10 from Dr. Flossie Wong-Staal of the NIH on or about July 6, 1984, and began generating nucleotide sequence data from BH-10 on or about July 18, 1984. By September 1, 1984, DuPont had run sequence reactions on DNA fragments that spanned what has now been determined to be the entire env region of BH-10's DNA. DuPont obtained U.S. Patent No. 4,861,707, issued in 1989 based on a February 1987 application, which states that a BglII-BamHI BH-10 DNA fragment encodes an immunoreactive polypeptide from the env region.
The NIH gave the BH-10 and BH-8 clones to Dr. Nancy Chang at Centocor on July 20, 1984, and also gave Centocor a restriction map for BH-10, BH-8, and BH-5. At some point after July 20, 1984, Dr. Chang and her colleagues started working on expressing recombinant env proteins through random and directed cloning. On or about July 26, 1984, Dr. Chang met with Dr. Scott Putney, an outside scientist who was working with Centocor on its HIV research, to plan Centocor's HIV clone research. A July 31, 1984 laboratory notebook entry by one Centocor scientist is entitled "Sequencing of SstI-HindIII fragment." This fragment SstI-HindIII is a BH-8 fragment that contains approximately 76% of the env region of BH-8. Dr. Chang drafted a statement, dated August 27, 1984, stating that Centocor had "sequenced a segment (about 3,500 base pairs long) of [HIV's DNA] encoding most of the env gene."
On October 10, 1984, Centocor filed U.S. Patent Application No. 659,339 ("'339 application"), which is still pending. The '339 application purports to set forth, inter alia, an env based recombinant HIV immunoassay, and lists the following expression vectors: "OmpA, pIN (A, B, and C), lambda pL, T7, lac, Trp, ORF and lambda gt11." It does not identify the HIV clones upon which it relies as starting material. The '339 application lists only Dr. Chang as an inventor, and lists Centocor as the assignee. It does not indicate that Dr. Chang deposited any of the HIV clones with the American Type Culture Collection ("ATCC")[5] on or before October 10, 1984, or refer to any ATCC deposit relating to HIV clones. On or about August 22, 1984, Dr. Wong-Staal, Dr. Robert Gallo, Dr. Beatrice Hahn, and a fourth NIH scientist deposited BH-10 and BH-8 with the ATCC, and filed U.S. Patent Application No. 643,306 ("'306 application"), purporting to set forth the process for cloning the complete HIV genome.
On August 9, 1984, Dr. Hahn and others submitted an article to the journal Nature that was published on November 8, 1984 as Molecular Cloning and Characterization of the HTLV-III Virus Associated with AIDS, 312 Nature 166 (1984). The article contains the first description in a scientific journal of BH-10, BH-8, and BH-5. On November 29, 1984, Dr. Chang, Dr. Wong-Staal and others submitted an article to the journal Nature which was published on January 24, 1985 as Complete Nucleotide Sequence of the AIDS Virus, HTLV-III, 313 Nature 277 (1985). On December 21, 1984, Dr. Chang and others submitted an article to the journal Science called Expression in Escherichia of Open Reading Frame Gene Segments of HTLV-III, which was published in April 1985. That article states that polypeptides produced from "fragments of HTLV-III DNA derived from BH-10" (numbers 127, 121 and 113) *1109 were immunoreactive. Figure 3 of the '339 application is a printout showing 3112 nucleotides from the HIV genome. Of the 3112 nucleotides there displayed, 883 fall within the env region of HIV, though the env nucleotides are not identified on the figure as such. The "Best Mode" section of the '339 application contains three separate embodiments of a recombinant HIV immunoassay. The second embodiment specifically discusses as examples the random breakage of three HIV DNA fragments EcoRI-EcoRI, KpnI-KpnI, and EcoRI-HindIII into 200-500 base pairs. The '339 application does not describe a method for obtaining HIV clones from the native virus.
On January 23, 1985, Centocor filed U.S. Patent Application No. 693,866 ("'866 application") with the PTO. The '866 application purports to set forth the complete nucleotide sequence of BH-10, BH-8, and BH-5. The '866 application lists only Dr. Chang as an inventor, and names Centocor as the assignee.[6] Clones 113, 121 and 127 described in the '866 application are from the env region, but not from the portion of the HIV env region for which sequence information was included in Figure 3 of the '339 application.
By October 1, 1984, Chiron had run sequence reactions on DNA fragments that spanned what has since been determined to be the entire env of HIV. On October 31, 1984, Chiron filed U.S. Patent Application No. 06/667,501, the ancestral patent application that subsequently led to the '949 patent, which was issued on October 22, 1992 to Chiron.[7] The '949 patent teaches that DNA fragments as short as 21 nucleotides can be used to generate immunoreactive polypeptides from HIV's env.
C. The Steimer DeclarationDuring the pendency of the application that later became the '949 patent, Chiron scientist Dr. Kathelyn Sue Steimer submitted a Rule 132 Declaration to the PTO, which she signed on September 14, 1990. The version of this declaration in the official PTO file does not have a mailroom stamp or other date stamp indicating when it was received at the PTO. However, the declaration was submitted with a Supplemental Response, which is date-stamped as having been received by the Board of Patent Appeals and Interferences on September 20, 1990. In her declaration, Dr. Steimer states that her expert opinion was that "the state of the art in October 1984 was at best speculative with respect to the general usefulness of recombinant antigens in immunoassays." She based this conclusion on a number of factors, including (1) Chiron's failure to develop a similar recombinant immunoassay for use with Hepatitis A virus (HAV), and (2) the fact that naturally derived HIV DNA varies greatly due to transcription error, while recombinant DNA does not, with the result that recombinant based immunoassays might not succeed in binding to actual HIV antibodies. Based on this assessment, Dr. Steimer made the critical conclusion that, "in October 1984 those of even greater than ordinary skill in the art could not have had any reasonable expectation that a HIV diagnostic using a recombinant antigen would have been as effective as the `native' HIV diagnostic then known."
In a submission filed with the government in May 1984, Chiron stated that it "is developing vaccines to protect cats against infection by the retrovirus FeLV. We believe that these efforts will have great significance in understanding, diagnosing, and perhaps treating and preventing AIDS since some of the fundamental pathological features are shared by FeLV and the retrovirus associated with AIDS." In April 1986, Chiron filed a patent application claiming, in part, "[a] particle immunogenic against HAV infection which particle comprises a polypeptide having an amino acid sequence capable of forming a particle when said sequence is produced in a eucaryotic host, and an epitope of *1110 HAV." This patent application is for an HAV vaccine, not an HAV assay or diagnostic, and does not mention the use of recombinant HAV polypeptides in a diagnostic.
On July 2, 1990, Examiner Christine Nucker forwarded a PTO Form 850 to the Board of Patent Appeals and Interferences in Interference No. 102,432. This interference involved a potential conflict between claims in the pending Chiron patent application (Application No. 07/138,894, which ultimately issued as the '949 patent and which was the subject of the Steimer Declaration), and a patent application by Essex et al. (Application No. 07/539,370). On the Form 850, Nucker indicated that there were allowable claims in the pending application that were in potential conflict with the Essex application, necessitating an interference. Specifically, under the section entitled "The claims of this party which correspond to this count," Nucker wrote "60-81 (allowable)." These are the claims that ultimately appeared as claims 1-22 of the '949 patent as issued.
In her March 1992 Notice of Allowability for the '949 patent, Examiner Nucker listed the communications from Chiron upon which she relied and to which she was responding. Dr. Steimer's declaration is not listed as such a communication. Other than the final Notice of Allowability, there is no evidence in the record that the PTO took any action subsequent to Dr. Steimer's declaration.
The invention described in the '949 patent is an immunoassay reactive with human AIDS sera based on recombinant DNA proteins from the env region of HIV.
LEGAL STANDARDUnder Federal Rule of Civil Procedure 56, summary judgment shall be granted:
against a party who fails to make a showing sufficient to establish the existence of an element essential to that party's case, and on which that party will bear the burden of proof at trial ... since a complete failure of proof concerning an essential element of the nonmoving party's case necessarily renders all other facts immaterial.Celotex Corp. v. Catrett, 477 U.S. 317, 322-23, 106 S. Ct. 2548, 2552, 91 L. Ed. 2d 265 (1986). The party moving for summary judgment has the "initial responsibility of informing the district court of the basis for its motion, and identifying those portions" of the record showing the absence of a genuine issue of fact. Id. at 323, 106 S. Ct. at 2553. The burden then shifts to the nonmoving party to present evidence sufficient to support a verdict in its favor on every element of its claim for which it will carry the burden of proof at trial. Id. at 322-23, 106 S. Ct. at 2552. "If the [nonmoving party's] evidence is ... not sufficiently probative ... summary judgment may be granted." Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 249-50, 106 S. Ct. 2505, 2511, 91 L. Ed. 2d 202 (1986).
Where the moving party has the burden of proof on a claim or defense raised in a summary judgment motion, it must show that the undisputed facts establish every element of the claim or defense. Meyers v. Brooks Shoe Inc., 912 F.2d 1459 (Fed.Cir. 1990). When the defendant in a patent infringement case moves for summary judgment on an affirmative defense, the elements of which the defendant must prove by clear and convincing evidence, the non-moving party must simply produce enough evidence to allow a rational trier of fact to find that there is not clear and convincing evidence. As a result of this unusual posture, the non-moving party's burden to come forward with evidence to prevent summary judgment is less stringent than that normally placed on a non-moving party. Schneider (USA) Inc. v. C.R. Bard Inc., 18 U.S.P.Q.2d 1076, 1080, 1990 WL 292143 (D.Mass.1990).
The court's function on a motion for summary judgment is not to make credibility determinations, Anderson, 477 U.S. at 249, 106 S. Ct. at 2510, and the inferences to be drawn from the facts must be viewed in a light most favorable to the party opposing the motion. T.W. Elec. Serv. v. Pacific Elec. Contractors Ass'n, 809 F.2d 626, 631 (9th Cir. 1987).
DISCUSSIONChiron's patent is presumed by statute to be valid. 35 U.S.C. § 282. Accordingly, *1111 in order to prevail on its inequitable conduct and prior invention defenses, Abbott must prove those defenses by clear and convincing evidence. Avia Group Int'l, Inc. v. L.A. Gear California, Inc., 853 F.2d 1557, 1562 (Fed.Cir.1988).
I. Inequitable ConductAbbott bases its inequitable conduct defense solely on Chiron's submission of the Steimer Declaration to the PTO in conjunction with Patent Application No. 07/138,894. Abbott argues that the Steimer Declaration contains material misrepresentations and omissions, and that it was intended to deceive the PTO. Specifically, Abbott contends that the declaration misrepresents the state of the art in 1984 by concluding that at that time, there could be no reasonable expectation that a recombinant DNA based immunoassay could be effective, and that it fails to mention previous work done by Chiron itself with recombinant DNA immunoassays for other viruses. Abbott also argues that it is irrelevant to the inequitable conduct defense whether the Steimer Declaration actually was received and considered by the PTO in making its allowability determination.
In response, Chiron argues first that the Steimer Declaration cannot form the basis of an inequitable conduct defense because it was submitted months after the claims had already been found allowable by the PTO. In the alternative, Chiron argues that the declaration does not contain material misrepresentations or omissions, and even if it does, there is insufficient evidence of intent.
A. Analytical FrameworkThe party asserting an inequitable conduct defense bears the burden of proving both intent and materiality by clear and convincing evidence. Braun Inc. v. Dynamics Corp. of America, 975 F.2d 815, 822 (Fed.Cir. 1992); see also Halliburton Co. v. Schlumberger Technology Corp., 925 F.2d 1435, 1443-44 (Fed.Cir.1991). Accordingly, Abbott must prove by clear and convincing evidence that the Steimer Declaration contained material misrepresentations or omissions and that Dr. Steimer intended to deceive the PTO.
Information is material if "there is a substantial likelihood that a reasonable examiner would consider [the information] important in deciding whether to allow the application to issue as a patent." 37 C.F.R. § 1.56(a); Halliburton, 925 F.2d at 1440. A finding of materiality alone, however, is insufficient to support a finding of an intent to deceive, which is a separate element of inequitable conduct. Thus, in attempting to prove inequitable conduct, the accuser may not rely solely on the materiality of information allegedly withheld. Braun, 975 F.2d at 822. To support a finding of inequitable conduct, the "involved conduct, viewed in light of all the evidence, including evidence indicative of good faith, must indicate sufficient culpability to require a finding of intent to deceive." Kingsdown Medical Consultants, Ltd. v. Hollister, Inc., 863 F.2d 867, 876 (Fed.Cir.1988), cert. denied, 490 U.S. 1067, 109 S. Ct. 2068, 104 L. Ed. 2d 633 (1989). Gross negligence is not in and of itself sufficient to establish inequitable conduct; rather, deceitful intent must be shown. Halliburton, 925 F.2d at 1442-43; Kingsdown, 863 F.2d at 876; see also Hewlett-Packard Co. v. Bausch & Lomb Inc., 882 F.2d 1556, 1562 (Fed.Cir.1989) (reckless indifference to the truth insufficient to show intent), cert. denied, 493 U.S. 1076, 110 S. Ct. 1125, 107 L. Ed. 2d 1031 (1990).
B. AnalysisAt the threshold, the court must determine whether the PTO actually considered the Steimer Declaration in deciding to grant the '949 patent. As Chiron points out, the Steimer Declaration was filed several months after Examiner Nucker made an initial determination of allowability, and other than the issuing of the final notice of allowability in March 1992, there is no direct evidence that the PTO took any action in response to (or otherwise considered) the declaration. In addition, Chiron has submitted two declarations from its putative expert stating that in his opinion, the PTO did not consider the Steimer Declaration. Goolkasian Decl. ¶ 12; Goolkasian Supp.Decl. ¶ 7. However, as Abbott argues, it would have been proper for the PTO to consider the declaration subsequent to the initial allowability determination, *1112 and there is circumstantial evidence that such consideration likely occurred.
Chiron is correct that Nucker made at least an initial finding of allowability of the claims in the '949 patent no later than July 2, 1990, when she forwarded the Form 850 to the Board of Patent Appeals and Interferences ("BPAI") based on claims 60-81 in the pending application.[8] Chiron also is correct that, pursuant to PTO rules, before Nucker could have sent the Form 850 to the BPAI, she first had to determine that the claims listed therein were otherwise patentable to Chiron. See Manual of Patent Examining Procedure ("MPEP") §§ 2305, 2306, 2307.02 (5th ed. 1994); see also 37 C.F.R. § 1.606 ("Before an interference is declared between an application and an unexpired patent, an examiner must determine that there is interfering subject matter claimed in the application and the patent which is patentable to the applicant subject to a judgment in the interference.").
However, this initial determination is not necessarily final, see MPEP at § 2341; 37 C.F.R. § 1.641, and the examiner-in-chief had the power to consider the Steimer Declaration as part of a sua sponte patentability analysis before making a final allowability determination, 35 U.S.C. § 135. Furthermore, there is evidence in the record, albeit circumstantial, that the PTO may actually have considered the Steimer Declaration subsequent to the filing of the Form 850. Specifically, the following circumstantial evidence is relevant to Abbott's allegation. On July 19, 1989, Examiner Nucker notified Chiron that she had rejected some of the claims in the application on the basis of obviousness. In direct response to that notice, Claims 60-81 were added by Chiron on January 19, 1990. Subsequently, on February 14, 1990, the PTO held an interview with a Chiron representative, at which Examiner Nucker was present. The report of that interview states that all claims were discussed, and that agreement was not reached on the issues discussed. The report sets forth two issues that apparently were discussed, one of which was: "diff. between lysate and recombinant assay (heterogeneity from innoculate (diff. isolates) + mutations in culture) due to hypervariation regions recombinant homogenous antigen."[9]
In late September 1990, Chiron filed its Supplemental Response with the PTO, which included the Steimer Declaration, an amendment of inventorship, and a supplemental list of references. The submission purported to be in further response to Nucker's July 19, 1989 action, though it also referenced the February 1990 interview.[10] In her declaration, Dr. Steimer directly addressed the problem cited in the report of the February 1990 interview referenced above the difference between a lysate (native) produced and a recombinant produced assay due to the heterogeneity of the native antigen (resulting from natural variations in the amino acid sequence) and the necessarily homogeneous nature of the recombinantly produced antigen. Steimer Decl. ¶ 8. Thus, it appears that the Steimer Declaration responded to questions raised by Nucker in the February 1990 interview that had, subsequent to the interview, not been answered any other way.[11]
*1113 The formal referral to the BPAI took place on September 28, 1990, subsequent to submission of the Steimer Declaration (and more than two months after Nucker filled out the Form 850). The formal reference indicates that claims 60-81 of the Chiron application were in potential conflict with the Essex application.
It is clear that on interference, the BPAI may consider patentability and may recommend rejection of a claim even if it is not involved in the interference. 37 C.F.R. §§ 1.655, 1.659; MPEP §§ 2314, 2355, 2359. The examiner-in-chief, who is responsible for declaring the interference, and the BPAI, have the entire application file. 37 C.F.R. § 1.609; MPEP § 2311. Furthermore, until the interference is declared the examiner continues to have jurisdiction over the pending application. 37 C.F.R. § 1.614(C); MPEP § 2314. In this case the interference was declared on or shortly before September 28, 1990. Until that time, Examiner Nucker (or another examiner) continued to have jurisdiction.
The Initial Memorandum so heavily relied upon by Chiron's expert bears the handwritten legend at the top: "Ready for Declaration MLC Caroff (9/28/90)" and the number "102432", which is the case number for this interference. Goolkasian Decl.Ex. 2. This legend is not explained on the document or by the parties. It may relate to the Notice of Declaration required by 37 C.F.R. § 1.611 and MPEP § 2311. In any event, Chiron's supplemental response, which included the Steimer Declaration, is stamped "Received" by the BPAI on September 21, 1990, seven days before Examiner-in-Chief Caroff declared the interference pursuant to section 1.610 of the regulations and MPEP § 2311. At any of these stages, the examiner, the examiner-in-chief, and the BPAI would have had the Steimer Declaration and likely would have considered it since it specifically addressed issues that remained outstanding.
The BPAI's ruling in favor of Chiron's claims came down on September 27, 1991, and the formal notice of allowability on claims 60-81 went out on March 20, 1992. In that notice, Examiner Nucker stated as her reason for allowability that: applicants were the first to realize the importance of utilizing recombinantly produced HIV envelope proteins as antigen standards in immunoassays for anti-HIV antibodies. By generating the envelope proteins recombinantly it is possible to control for the high rate of mutation seen in these proteins when produced by virally infected cells. This control results in improved assay results when compared with extant commercially available kits.This language appears to relate to the questions raised in the February 1990 interview and the answers provided, in part, by Dr. Steimer in her declaration. A reasonable factfinder therefore could infer that despite Examiner Nucker's failure to list the Steimer Declaration as one of the Chiron documents upon which she relied and to which she was responding, she, another examiner, the examiner-in-chief, or the BPAI actually had considered the content of the Steimer Declaration in making a final determination. Absent such an inference, the record contains no post-interview evidence that Nucker's critical questions regarding the heterogeneity/homogeneity problem ever were answered. That problem was of sufficient import to prompt the February 1990 inquiry, the Steimer Declaration responded to it, and the March 20, 1992 allowance specifically referenced it.[12]
Accordingly, based on the record of the patent prosecution before the PTO, there is a substantial likelihood, and a reasonable factfinder could conclude, that someone at the *1114 PTO actually considered, or that a reasonable examiner in such circumstances would have considered, the Steimer Declaration in making the final allowability determination. Thus, the court must proceed to analyze whether there is sufficient evidence from which a reasonable factfinder could (or must) find by clear and convincing evidence that the Steimer Declaration evidences both materiality and intent within the meaning of inequitable conduct.
Abbott cites four allegedly material misrepresentations/omissions in the Steimer Declaration, and the court will examine each in turn.
1. Status of the HAV ProjectAbbott first points to Steimer's discussion of the status of Chiron's HAV project, which she characterized as a "complete failure" because "virtually none" of the recombinant antigens bound with antibodies to the virus. Steimer Decl. ¶¶ 6-7. Steimer also stated that the HAV project ultimately was abandoned because of the unpredictable results from the recombinant HAV immunoassay. Id. Abbott argues that these statements constitute a material misrepresentation because Steimer stated that the HAV project failed in 1984, when the project in fact was not abandoned until two years later, such that its failure was not relevant to the state of the art in 1984. Abbott also contends that in fact, the state of the art in 1984 was a belief that recombinant antigens would work.
Abbott's reliance on Steimer's statements regarding the HAV project is misplaced. Dr. Steimer did not represent in her declaration that the HAV project failed in 1984; instead, she stated that in 1984 the HAV virus was better characterized than HIV, and that the HAV project nonetheless failed and ultimately was abandoned. Steimer Decl. ¶¶ 6-7. She also couched her statement in the present tense: she stated that "a case which illustrates that producing a successful recombinant immunoassay is not merely a hypothetical problem is shown by Chiron's work with [HAV]." Id. at ¶ 6 (emphasis supplied). Nothing in this language implies that the HAV project already had failed or been abandoned in 1984.
The only reasonable reading of the Steimer Declaration is that in 1984, the HAV virus was sufficiently well understood to justify an attempt at creating a recombinant based immunoassay, that that attempt ultimately failed, and that such failure illustrates that successful use of recombinant based immunoassays therefore is not now, and was not in 1984, guaranteed. When the language in the declaration is viewed in the context of the entire declaration, no rational factfinder could conclude that this statement is a material misrepresentation of fact.[13]
Furthermore, Abbott's argument that in 1984 the state of the art was a belief that recombinant antigens would work is not in fact contradicted by the Steimer Declaration. Dr. Steimer concluded only that "the state of the art in October, 1984 was at best speculative with respect to the general usefulness of recombinant antigens in immunoassays." Steimer Decl. ¶ 5. There is nothing in any of the evidence submitted by either party that indicates that this (fairly equivocal) conclusion was inaccurate. Indeed, far from calling Steimer's statement into question, Abbott's emphasis on the fact that Chiron did not even express recombinant proteins from HAV until 1985 bolsters the statement's accuracy.
No reasonable factfinder could conclude that Steimer's statement regarding the status of the HAV work constituted a material misrepresentation, and Abbott cannot rely on the HAV work to support its inequitable conduct defense.
2. Omission of the HBV ProjectAbbott next argues that Steimer selectively excluded successful work Chiron had done prior to October 1984 with the HBV virus. Specifically, Abbott contends that Steimer *1115 failed to mention that Chiron had created an HBV diagnostic kit by October 1984, and contends that the work with HBV was far more relevant to the HIV project than the failed HAV project, and that its omission was material.
Abbott provides sufficient evidence of a material omission to survive, though not prevail upon, summary judgment with respect to the HBV work.
Abbott has submitted undisputed evidence that by 1984 Chiron had successfully created a recombinant based HBV diagnostic kit, and that Chiron represented in a project application with the U.S. Department of Health and Human Services in 1984 that an HIV immunoassay possibly could follow on that model. Abbott Ex. 2U at 1205775; Dina Depo. at 424-27. While there is no evidence in the record that the work with HBV was somehow more relevant to the HIV work than the failed HAV project,[14] certainly Chiron thought it sufficiently relevant to the HIV work to make that representation part of an application for a government HIV project, Abbott Ex. 2U at 1205775, and its success in creating a recombinant based immunoassay for HBV stands in fairly stark contrast to the failed HAV project which Steimer chose to report to the PTO.[15]
The court finds it difficult on the current record to understand how the HBV work could be relevant to Chiron's government HIV project application and at the same time not be material to the patent application, particularly to Steimer's declaration. A reasonable factfinder could conclude by clear and convincing evidence that Steimer's failure to report the successful HBV project constituted a material omission, and further *1116 could infer that by referencing the failed HAV project but not the successful HBV work, Chiron intended to deceive the examiner as to the state of the art in October 1984. Accordingly, Abbott is entitled to rely on Chiron's omission of the HBV work to support its inequitable conduct defense, though it is not itself entitled to prevail upon that defense as a matter of law.
3. Omission of the FeLV ProjectAbbott next argues that Steimer selectively excluded successful work Chiron had done prior to October 1984 with the FeLV virus. Specifically, Abbott contends that Steimer failed to mention that Chiron had successfully expressed immunoreactive env proteins from FeLV prior to October 1984, and contends that the work with FeLV was far more relevant to the HIV project than the failed HAV project, and that its omission therefore was material.
Abbott provides sufficient evidence of a material omission to survive, though not prevail upon, summary judgment with respect to the FeLV work.
While Chiron is correct that the evidence in the record reveals that its work with FeLV was aimed at creating a vaccine, not an immunoassay, Abbott Ex. 2U at XXXXXXX-XX, it also is undisputed that as part of that work Chiron created recombinant FeLV env antigens and determined their reactivity with antibodies to the virus. Luciw Depo. at 220-23; Abbott Ex. 2U at 1205775; Abbott Ex. 8P at 1230417.[16] There also is evidence in the record that because FeLV and HIV are both retroviruses, they have many similarities, and as a result Chiron's own scientists believed that the FeLV project was more relevant to the HIV work than their work with other viruses. Dina Depo. at 480. Attempting to justify its omission of the FeLV work from the Steimer Declaration, Chiron relies on the fact that the FeLV recombinant vaccine ultimately failed. Dina Depo. at 237-39. However, Chiron is unable to produce any evidence of the date the FeLV project failed (Dr. Dina testified only that it was "sometime" after September 1984), and the ultimate failure of the vaccine itself does not alter the very relevant fact that as part of its FeLV project, Chiron was successful in expressing recombinant env FeLV proteins that were immunoreactive with the virus. This fact alone makes the FeLV work directly relevant to the specific issues addressed in the Steimer Declaration (i.e. the efficacy of a recombinant immunoassay).[17]
A reasonable factfinder could conclude by clear and convincing evidence that Steimer's failure to report the successful FeLV project constituted a material omission, and further could infer that by referencing the failed HAV project but not the successful FeLV work, Chiron intended to deceive the examiner as to the state of the art in October 1984. Accordingly, Abbott is entitled to rely on Chiron's omission of the FeLV project to support its inequitable conduct defense, though it is not itself entitled to prevail upon that defense as a matter of law.
4. Paragraph 4 of the Steimer DeclarationAbbott finally argues that Dr. Steimer's expert opinion that "in October 1984 those of even greater than ordinary skill in the art could not have had any reasonable expectation that a HIV diagnostic using a recombinant antigen would be as effective as the `native' HIV diagnostic then known," Steimer Decl. ¶ 4, is absolutely indefensible. Specifically, *1117 Abbott argues that in 1983 and 1984, Chiron's own scientist, Dr. Luciw, had a "high level of expectation" that the recombinant HIV diagnostic would work, Luciw Depo. at 148-49, such that the invention would not overcome the examiner's obviousness rejection. Abbott also points to Steimer's own admission (and Dr. Dina's concurrence) that her opinion was "too strong," Steimer Depo. at 167-69, 211-12; Dina Depo. at 562-63, and that instead the truth was that in 1984 there would be no reasonable "certainty" that it would work. Steimer Depo. at 168-69; Dina Depo. at 562-63. Abbott argues that a "lack of certainty" is materially different from "no reasonable expectation," and that the properly qualified opinion would not have overcome an obviousness rejection.
In response to this evidence, Chiron argues first that Dr. Steimer's feelings now regarding the accuracy of her declaration in 1990 are irrelevant, especially in light of the fact that she also has testified that at the time of the declaration, she believed in its fundamental accuracy. Steimer Depo. at 171, 204. Chiron also argues that Dr. Luciw did not testify that he had a high expectation of success that the recombinant HIV diagnostic would work as well as a native assay, but that he had a high expectation of achieving "demonstration of AIDS virus recombinant antigen reacting with antibodies from an infected host." Luciw Depo. at 149. Chiron argues that this testimony must be considered in the context of Luciw's further testimony that he agrees with the statement in paragraph 4. Luciw Depo. at 175, 179. Chiron also contends that it made it clear to the PTO that Steimer was not claiming that no one could have expected recombinant assays to have some usefulness, just that no one could have expected them to be as or more useful than native assays. See Chiron's Sept. 1990 Supp.Response at 4. Finally, Chiron's putative expert states that in his opinion, paragraph 4 was not intended to, and did not in fact, deceive the PTO. Goolkasian Decl. ¶ 15.
Chiron cites no authority for the proposition that its own scientists' admissions that statements made before the PTO were too strong are somehow irrelevant. Indeed, these admissions are perhaps the most damning evidence against Chiron. Chiron is correct that Dr. Luciw's testimony does not directly contradict paragraph 4 of the Steimer Declaration, and that Chiron was careful in its 1990 submission to caution the PTO that it was not claiming that there could have been no expectation that recombinant assays would be useful. See Chiron's Sept. 1990 Supp. Response at 4 ("Applicants are not arguing that some minimal degree of antigenicity was unpredictable. Rather, it is applicants' position that the performance of the recombinant env-based immunoassays ... is unexpectedly high in that it was as good or better than nonrecombinant assays."). However, while this language constitutes evidence of good faith for a factfinder to consider in its intent analysis, it does not go to materiality, and cannot alone overcome Dr. Steimer's own admission (concurred in by Dr. Dina) that her statement in paragraph 4 was too strong. Accordingly, notwithstanding Chiron's expert testimony, a reasonable factfinder could conclude that Steimer's opinion on this specific subject was material in that it enabled Chiron to overcome an obviousness rejection.
However, while there is sufficient evidence from which a reasonable factfinder could conclude by clear and convincing evidence that Steimer's statement in paragraph 4 is material, there is insufficient evidence of intent for Abbott to survive past summary judgment. The only evidence in the record that Chiron intended to deceive the PTO is Steimer's testimony that the exact wording of the paragraph, including the critical language "any reasonable expectation," was drafted for her by a lawyer, upon whom she relied to "use the appropriate language," Steimer Depo. at 169, and the fact that a misleading declaration was submitted in response to questions raised by the examiner.
In response, Chiron has offered evidence of its own good faith in its submission accompanying Steimer's declaration. In that submission Chiron tries to clarify the meaning of Steimer's statement regarding expectations of the effectiveness of recombinant immunoassays in 1984. See Chiron's Sept. 1990 Supp.Response at 4. Indeed, in that supplemental *1118 response, Chiron was quite candid regarding its contention, stating that "[a]pplicants are not arguing that some minimal degree of antigenicity was unpredictable. Rather, it is applicants' position that the performance of recombinant env-based immunoassays ... is unexpectedly high in that it was as good as or better than nonrecombinant assays." Id. Given the heavy burden that Abbott bears, the court concludes that faced with the evidence of Chiron's good faith and only the minimal evidence of Dr. Steimer's intent to deceive, no reasonable factfinder could conclude by clear and convincing evidence that Steimer had the requisite intent to deceive the PTO in her declaration based on paragraph 4. Accordingly, Abbott cannot meet its burden by relying on this paragraph to support its inequitable conduct defense, and Chiron is entitled to summary judgment on that issue.
C. SummaryFor the reasons set forth above, the court concludes that there is sufficient evidence in the record for a reasonable factfinder to conclude that the PTO considered the Steimer Declaration in making its final allowability determination. Thus, Abbott is entitled to proceed to trial upon an inequitable conduct defense on some of the alleged misrepresentations/omissions. Specifically, Abbott is entitled to proceed upon, but not itself entitled to summary judgment on, its inequitable conduct defense based upon (1) Dr. Steimer's failure to reference the HBV project; and (2) Dr. Steimer's failure to reference the FeLV project. Abbott cannot, as a matter of law, base its inequitable conduct defense on (1) Steimer's representations as to the status of the HAV project, or (2) Steimer's statement in paragraph 4.
II. Prior Invention A. Analytical FrameworkIn order to prove prior invention, Abbott must establish by clear and convincing evidence that the invention claimed in the '949 patent was made first by another party who had not abandoned, suppressed, or concealed it. 35 U.S.C. § 102(g). "Priority goes to the first party to reduce an invention to practice unless the other party can show that it was first to conceive the invention and that it exercised reasonable diligence in later reducing that invention to practice." Price v. Symsek, 988 F.2d 1187, 1190 (Fed.Cir.1993).[18] The testimony of an alleged prior inventor or inventors, standing alone, is insufficient to prove prior invention; it must be corroborated by other evidence. Id. at 1194-95. The alleged inventor's laboratory notebooks suffice for purposes of corroboration, even where they are not contemporaneously witnessed by the inventor. Hybritech Inc. v. Monoclonal Antibodies, Inc., 802 F.2d 1367, 1378-79 (Fed.Cir.1986), cert. denied, 480 U.S. 947, 107 S. Ct. 1606, 94 L. Ed. 2d 792 (1987).
B. AnalysisChiron filed its original patent application on October 31, 1984, which therefore constitutes the date upon which Chiron constructively reduced the invention to practice.[19] Accordingly, in order to prevail on its prior invention defense, Abbott must establish by clear and convincing evidence that prior to October 31, 1984, someone other than Chiron was the first to conceive of the invention and diligently reduced it to practice.
Abbott contends that both NIH/Centocor and DuPont beat Chiron's invention date.[20] Specifically, Abbott argues that (1) both NIH/Centocor and DuPont conceived of the invention prior to Chiron, (2) NIH/Centocor actually reduced the invention to practice prior to Chiron, and (3) both NIH/Centocor and DuPont diligently reduced the invention to practice in a timely manner.
In response, Chiron contends that there is no evidence of prior invention. Specifically, *1119 Chiron argues that (1) it was the first to conceive of the invention and reduce it to practice, (2) under the doctrine of simultaneous conception and reduction to practice, it prevails because it was the first to reduce the invention to practice, and (3) the alleged prior inventors did not exercise diligence in reducing the invention to practice, and/or abandoned it.
The court must first determine as a matter of law what constitutes conception and reduction to practice in the instant context.
1. ConceptionConception is the formulation of a "definite and permanent idea of the complete and operative invention, as it is hereafter to be applied in practice." Burroughs Wellcome Co. v. Barr Labs., Inc. 40 F.3d 1223, 1228 (Fed.Cir.1994) (citation omitted). It "necessarily turns on the inventor's ability to describe his invention with particularity," and the idea must be sufficiently formed so that "only ordinary skill would be necessary to reduce the invention to practice, without extensive research or experimentation." Id. However, in the ordinary context, an inventor need not know or demonstrate that the invention actually works for conception to be complete that discovery is part of reduction to practice, not conception. Id.
Chiron half-heartedly argues first that conception of the instant invention requires merely having the idea for a recombinant immunoassay based on env region polypeptides, and disclosure of that idea to others.[21] In the alternative, Chiron argues that because the instant invention involves isolation of proteins at the genetic level, the doctrine of simultaneous conception and reduction to practice applies, such that conception was not complete until there was actual reduction to practice.[22]
Abbott contends that more is required for conception than just the idea of expressing an immunoreactive polypeptide from the env region of HIV; rather, Abbott argues, a specific DNA fragment that can be used to express an immunoreactive polypeptide must be identified by restriction sites (i.e., a restriction map of the DNA must be created). Abbott also argues that conception in this instance does not require actual gene sequencing of the env region that the doctrine of simultaneous conception and reduction to practice does not apply, and that all that is required for conception is creation of a restriction map identifying specific DNA fragments that possibly could be immunoreactive.
The court must determine whether conception of the instant invention requires (1) simply formulating the idea of a recombinant immunoassay based on env region polypeptides, as Chiron initially contends, (2) creating a restriction map and identifying specific possibly useful DNA fragments from the env region, as Abbott argues, or, (3) actual reduction to practice, including sequencing and analysis of the env region to ensure that the identified fragments actually are from the env, as Chiron argues in the alternative.
The Federal Circuit has held that
[a] gene is a chemical compound, albeit a complex one, and it is well established in our law that conception of a chemical compound requires that the inventor be able to define it so as to distinguish it from other materials, and to describe how to obtain it. [citation omitted]. Conception does not occur unless one has a mental picture of the structure of the chemical, or is able to define it by its method of preparation, its physical or chemical properties, or whatever characteristics sufficiently distinguish it. It is not sufficient to define it solely by its principal biological property, e.g. encoding human erythropoietin, because an alleged conception having no more specificity than that is simply a wish to know the identity of any material with that biological property.Amgen, Inc. v. Chugai Pharmaceutical Co., Ltd., 927 F.2d 1200, 1206 (Fed.Cir.), cert. denied sub. nom., 502 U.S. 856, 112 S. Ct. 169, *1120 116 L. Ed. 2d 132 (1991). Based on this rationale, the court held that "when an inventor is unable to envision the detailed constitution of a gene so as to distinguish it from other materials, as well as a method for obtaining it, conception has not been achieved until reduction to practice has occurred, i.e., until after the gene has been isolated." Id. On the facts of Amgen, the court concluded that a putative inventor did not have conception of an invention for cloning a gene, because he had only the general idea for the cloning but had not isolated and did not know the chemical structure (i.e. the nucleotide sequence) of the gene. Id. at 1207; see also Fiers v. Revel, 984 F.2d 1164, 1169 (Fed.Cir.1993) (holding that it is not sufficient for conception simply to describe a DNA-based invention by its "hoped-for function.").
With respect to chemical compounds, the Federal Circuit has held that conception "includes knowledge of both the specific chemical structure of the compound and an operative method of making it." Burroughs Wellcome, 40 F.3d at 1229. In every case in which it analyzed conception of an invention involving DNA encoding a human protein, the Federal Circuit has held that an inventor does not have knowledge of the specific chemical structure (and thus conception) until the inventor knows the nucleotide sequence of the relevant DNA and has a viable method for obtaining it. Id.; Fiers, 984 F.2d at 1168-69; Amgen, 927 F.2d at 1206; see also Colbert v. Lofdahl, 21 U.S.P.Q.2d 1068, 1071 (Bd.Pat.App. & Interf.1991). These cases have established what has become known as the doctrine of simultaneous conception and reduction to practice: until experimentation reveals the chemical structure of the protein (i.e. its nucleotide sequence) there is no "conception." Hereinafter, the court will refer to this merging of conception and reduction to practice as "hybrid conception."[23]
The instant case falls squarely within the rationale and holdings of the Amgen/Burroughs Wellcome line of cases. The mere idea of a recombinant immunoassay based on env region polypeptides, without knowledge and analysis of the nucleotide sequence of specific env DNA fragments, is, as the court in Amgen put it, "simply a wish to know the identity of any material" that would be immunoreactive with HIV, not a "definite and permanent idea of the complete and operative invention." Amgen, 927 F.2d at 1206-07; see also Fiers, 984 F.2d at 1169 ("conception of a DNA ... requires a definition of that substance other than by its functional utility."). Until the inventor possesses knowledge of both the nucleotide sequence of an HIV fragment from the env, and has an operative method of isolating that fragment, the mere idea that immunoreactive polypeptides from the env region would be capable of serving as an immunoassay (its functional utility) is inadequate as a matter of law to constitute conception.[24]
Abbott's attempt to distinguish the Amgen/Burroughs Wellcome line of cases fails. Abbott argues that in Fiers and Amgen, the invention involved a DNA sequence encoding a complete human protein, such that knowledge of the entire sequence from beginning to end was required to ensure that the whole protein was encoded. By contrast, Abbott argues, the instant invention involves only a DNA fragment, which Abbott contends can be described adequately by restriction sites alone, without any sequencing knowledge. Based upon a review of all the submissions before the court, including those submitted in response to the tentative order, this court finds this argument unpersuasive. As an initial matter, the Board of Patent Appeals and Interferences has applied the Amgen/Burroughs Wellcome doctrine to an invention involving a protein fragment, finding that in order to have the chemical structure of a protein or its fragment, the inventor *1121 must isolate the DNA molecule and know its nucleotide sequence. See Colbert, 21 U.S.P.Q.2d at 1071. Furthermore, in the context of the instant invention, all of the evidence in the record reveals that until the inventor had precisely located the env via sequencing, the inventor could not be certain that any expressed protein was indeed from the env region. Putney Depo. at 34-35; Dina Depo. at 494; Luciw Depo. at 440-41; Chang Depo. at 1088; Weiss Decl. ¶ 15; Wong-Staal Depo. at 182-83. Thus, as in Amgen and Fiers, where the inventor could not be sure that the complete desired protein was encoded without knowing the entire nucleotide sequence, here the inventor could not be sure that the expressed protein was the desired protein (i.e. from the env) without locating the env region by sequencing.[25]
Under the doctrine of simultaneous conception and reduction to practice, therefore, conception of the instant invention did not occur until there was hybrid conception. Accordingly, in order to prevail on its prior invention defense, Abbott must establish by clear and convincing evidence that a party other than Chiron was first to complete hybrid conception of the invention described in the '949 patent.
2. Hybrid Conception/Reduction to PracticeAn inventor can demonstrate reduction to practice by establishing either constructive or actual reduction to practice.
The act of filing a patent application constitutes a constructive reduction to practice of the invention described therein. Hazeltine Corp. v. United States, 820 F.2d 1190, 1196 (Fed.Cir.1987). However, to constitute constructive reduction to practice, the application must, inter alia, satisfy the disclosure requirements of 35 U.S.C. § 112: it must set forth a written description of the invention, enable one of ordinary skill in the art to make and use the invention, and set forth a "best mode" for carrying out the invention. See Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 1560 (Fed.Cir.1991). It is not disputed that Chiron completed the first step in constructively reducing the invention to practice by no later than October 31, 1984, when it filed its patent application.[26]
"Actual reduction to practice requires a showing that the embodiment relied upon as evidence of priority actually worked for its intended purpose." DSL Dynamic Sciences v. Union Switch & Signal, 928 F.2d 1122, 1125 (Fed.Cir.1991) (citation omitted). Both parties agree, and the court concludes, that actual reduction to practice (and therefore hybrid conception) of the instant invention occurred when the inventor (1) expressed recombinant proteins (2) known to be from the env region of HIV that (3) were immunoreactive with HIV-infected sera. As part of hybrid conception, the inventor necessarily *1122 must have sequenced the env region of HIV and have knowledge of the precise location of the env on the genome to ensure that the expressed proteins were in fact from the env.
3. DiscussionHaving determined as a matter of law that for purposes of the instant invention, priority goes to the party that first completed hybrid conception, and having established the requirements for hybrid conception, the court must determine on the voluminous factual record whether Abbott necessarily has or could establish by clear and convincing evidence that someone other than Chiron was first to reduce the invention to practice. Exhaustive review of the evidence and briefing submitted by both parties in conjunction with this motion reveals that the technology at issue is highly complex, and the import of actions taken by the various research teams in their race to invent an immunoassay difficult to decipher. Analyzing all of the evidence in the record in the context of the above rulings, the court concludes that neither party is entitled to prevail on summary judgment on Abbott's priority defense.
Abbott can prevail on its prior invention defense only by submitting clear and convincing evidence that some other party completed hybrid conception, either by constructively or actually reducing it to practice, before Chiron did. It is undisputed for purposes of this motion that Chiron completed the first step toward constructively reducing the invention to practice on October 31, 1984, and Chiron argues that it actually reduced the invention to practice in late September 1984.
Abbott does not directly challenge Chiron's alleged October 31, 1984 constructive reduction to practice.[27] Instead, Abbott argues that both NIH/Centocor and DuPont conceived of the invention (under the traditional standard) prior to October 31, 1984 and diligently reduced it to practice thereafter, and that NIH/Centocor actually reduced the invention to practice prior to Chiron. Abbott also argues that NIH/Centocor constructively reduced the invention to practice on October 10, 1984 by filing the '339 application, and thereby reduction to practice prior to Chiron.
In response, Chiron contends that no other party succeeded in actually reducing the invention to practice prior to October 31, 1984, the date of its constructive reduction to practice. Chiron also argues that NIH/Centocor's filing of the '339 application on October 10, 1984 cannot constitute constructive reduction to practice because that application was legally insufficient in several critical ways.
a. Chiron's September 1984 WorkChiron contends that in addition to constructively reducing the invention to practice on October 31, 1984, it actually reduced the invention to practice on September 26, 1984, when Dr. Luciw, the inventor of the '949 patent, claims to have first successfully expressed an HIV polypeptide from the Eco-RI-Kpn fragment which tests confirmed was both from the env and immunoreactive with human AIDS sera.
Abbott contends that Chiron's late September 1984 work cannot constitute actual reduction to practice because Chiron lost Luciw's laboratory notebook. Abbott argues that Luciw's testimony is thus the uncorroborated testimony of a putative inventor, which cannot as a matter of law suffice for purposes of priority.
In support of its contention that Dr. Luciw successfully reduced the invention to practice in late September 1984, Chiron submits the following evidence: (1) Luciw's own testimony that on September 26, 1984 he expressed the EcoRI-Kpn fragment of HIV clone pS7c/7D, which he and Dr. Dina confirmed by an immunofluorescence test was a recombinant env protein that was immunoreactive with human AIDS sera; Luciw Depo. at 116-20; Luciw Decl. ¶ 4; (2) Dr. Dina's testimony recalling his and Luciw's successful immunofluorescence test in late September 1984; *1123 Dina Depo. at 165-66; (3) Dr. Sanchez-Pescador's testimony that as part of Luciw's team, he sequenced the entire env region of the HIV genome and knew its boundaries by late September 1984; Sanchez-Pescador Depo. at 39-40; (4) photographs of the tubes Luciw used in his experiment, which bear the labels "SV7c" or "7D", "Eco + Kpn", and which are dated 9/22/94; Luciw Decl. ¶ 4 & Exs. A-C; (5) an excerpt from the notebook of Dr. Barr, who Luciw asked on 9/27/84 to modify the SV7c/7D vector as part of an experiment that was derivative of the expression of the EcoRI-Kpn fragment, as well as a photograph of the tube used for that experiment, which is dated 9/28/84 and bears the label "SV7c/7D env gel; × Eco + Sac"; Luciw Decl. ¶ 6 & Exs. D & E; (6) an excerpt from the notebook of Maryann Wormstead, a Chiron lab tech, which confirms Luciw's statement that he repeated the experiment in early October; Luciw Decl. ¶ 7 & Ex. F; and (7) slides and photographs of the results of the early October repeat experiments; Luciw Decl. ¶ 8 & Exs. G-J. Other than pointing to the absence of Luciw's notebook, Abbott offers no evidence of its own to contradict Luciw's testimony.
Review of the evidence submitted by Chiron reveals that Luciw's testimony is not, as Abbott contends, entirely without corroboration. Certainly, there is substantial circumstantial evidence to corroborate his claim that in late September 1984 he successfully expressed an immunoreactive polypeptide from the env region of HIV. However, the court is deeply troubled by the absence of the one piece of evidence that could directly corroborate (or, perhaps, contradict) Luciw's testimony his laboratory notebook. Its absence arouses suspicion. Despite the other potentially corroborating evidence in the record, absent the notebook the court cannot and will not determine as a matter of law that Dr. Luciw's late September 1984 work constituted successful reduction to practice. However, considering all of the evidence submitted by Chiron, a reasonable jury certainly could reach that conclusion. Therefore, while Chiron is not entitled to summary judgment that it reduced the invention to practice in late September 1984, Abbott also is not entitled to summary judgment on priority unless it can submit clear and convincing evidence that someone else reduced the invention to practice prior to late September 1984, because a reasonable jury could conclude that Chiron reduced to practice on that date.
b. NIH/Centocor Actual ReductionAbbott contends that NIH/Centocor actually reduced the invention to practice prior to October 31, 1984.[28] Specifically, Abbott argues that NIH/Centocor sequenced a segment of HIV's DNA encoding "most" of the env region by late August 1984, that it sequenced the entire env by late August or early September 1984, and that it began successfully expressing immunoreactive polypeptides from the env soon thereafter, as early as mid to late October 1984.
In support of Abbott's contention, there is the following evidence in the record: (1) Dr. Chang met with Dr. Putney on July 26, 1984 to discuss a DNA fragment on the BH-8 restriction map called SstI-HindIII, which they hypothesized to encode the env; Joint Statement ¶ 30; Putney Depo. at 36-41, 48; (2) Chang and Putney discussed using this fragment and subfragments thereof to produce recombinant polypeptides, and over the next few days they prepared written time schedules to memorialize their intentions; Putney Depo. at 36-38, 40-49, 124-26; Abbott Ex. 2E ("Putney Notebook") at 16744-48; Chang Depo. at 875-76; (3) in July 1984 Dr. Ghrayeb had a working hypothesis that the SstI-HindIII fragment contained immunoreactive env polypeptides, and a July 31, 1984 entry in his notebook is entitled "Sequencing of SstI-HindIII fragment," which was a BH-8 fragment that contains approximately 76% of the env region of BH-8; Ghrayeb Depo. at 407-10; Joint Statement ¶¶ 31-32; (4) notebooks kept by Centocor scientists reflect experimentation with the SstI-HindIII fragment beginning in July 1984 and continuing thereafter; Abbott Ex. *1124 3, Huang Decl. ¶ 7-10; Abbott Ex. 3A ("Huang Notebook") at 23-220; Abbott Ex. 2G ("Ghrayeb Notebook") at 343-83, 387-91, 425, 437-47; (5) by August 10, 1984, Centocor scientists expressed a polypeptide from the SstI-HindIII fragment that they suspected was an env gene fragment; Putney Depo. at 102-04; Putney Notebook at 16755; (6) by late August 1984 Centocor sequenced all of the BH-8 clone; Chang Depo. at 879; (7) by early September, NIH sequenced all of the BH-8 clone; Ratner Depo. at 18, 29, 112-13; (8) on September 7, 1984, Chang wrote a memorandum about her meeting with Dr. Gallo and Dr. Wong-Staal in which she reported Centocor's "data on the cloning and expression of HTLV-III env gene in E. coli host cell and its immunoreactivity to AIDS patient serum"; Abbott Ex. 2F; (9) by October 10, 1984, Centocor identified six clones (out of 1000 tested) that "express[ed] HTLV-III-env-B-galactosidase fusion proteins (antigens) that cross react with the HTLV-III specific antibody", and two of these clones (4 and 107) were subfragments of the SstI-HindIII fragment; Abbott Ex. 2N ("'339 application") at A4356-57, 4384; Ghrayeb Depo. at 418-24; Ghrayeb Notebook at 441; (10) on October 20, 1984 Chang and Putney discussed the immunoreactivity of clone 121, which is from a subfragment of the SstI-HindIII fragment that encodes a portion of the env region of HIV; Putney Depo. at 120-26; Putney Notebook at XXXXX-XXX; (11) on November 29, 1984, Dr. Chang, Dr. Wong-Staal, and others submitted an article to the journal Nature which was published on January 24, 1985 as Complete Nucleotide Sequence of the AIDS Virus, HTLV-III, 313 Nature 277 (1985); Abbott Ex. 2K; (12) by December 4, 1984 NIH/Centocor determined the immunoreactivity of polypeptides from subfragments of the SstI-HindIII fragment; Putney Notebook at 16837-40; Abbott Ex. 2H; (13) on December 21, 1984, Dr. Chang and others submitted an article to the journal Science called Expression in Escherichia of Open Reading Frame Gene Segments of HTLV-III, which was published in April 1985, and which states that polypeptides produced from HIV clones (numbers 127, 121 and 113) were immunoreactive, and that these clones were taken from "fragments of HTLV-III DNA derived from BH-10"; Abbott Ex. 2H.
In response, Chiron argues that the NIH/Centocor scientists did not successfully reduce the invention to practice prior to October 31, 1984. Specifically, Chiron argues that prior to October 31, 1984 the NIH/Centocor scientists did not know for sure that the proteins they were expressing were from the env region because they had not successfully sequenced the env and did not know either its precise boundaries or exact location, and that there is no evidence in the record that NIH/Centocor successfully determined immunoreactivity prior to October 31, 1984.
In support of Chiron's argument, there is the following evidence in the record: (1) in August and September 1984, NIH/Centocor was not focussed on just the SstI-HindIII fragment as Abbott argues they were testing many fragments based on random cloning, not directed expression, because they did not know yet the precise location of the env; Wong-Staal Depo. at 114-15, 132; Chang Depo. at 577-79; Ghrayeb Depo. at 100-01; (2) Dr. Huang's September 3, 1984 positive test for immunoreactivity with the EcorI-HindIII fragment was a false positive he had no success at immunoreactivity until some unknown date after September 30, 1984; Huang Chiron Decl. ¶¶ 7-10; Huang Supp.Chiron Decl. ¶¶ 4-5; (3) NIH/Centocor's hypothesis as to the precise location of the env was wrong; Huang Chiron Decl. ¶ 13; Shearman Decl. ¶¶ 6-7; Weiss Decl. ¶¶ 5-7; (4) Chang's assertion regarding Centocor's August 1984 sequencing of the env is uncorroborated and directly contradicted in the record by other Centocor scientists, which indicates that Centocor was not in possession of the sequencing information even by late September 1984; Ghrayeb Depo. 80-82, 90-91, 259; Huang Chiron Decl. ¶¶ 11-12; Shearman Decl. ¶ 12; (5) even once NIH/Centocor scientists completed sequencing the env, they still did not know its precise location or boundaries; Ratner Depo. at 158-59; Livak Depo. at 93, 102-03, 148-49; (6) the '339 application itself, filed on October 10, 1984, does not contain accurate sequencing of or correct boundaries for the *1125 env region; '339 Application at Figure 3; Chang Depo. at 278-281; (7) the October 10, 1984 identification of two immunoreactive fragments in the '339 application is not corroborated by any notebook evidence other than one undated note in the Ghrayeb notebook which was not written by Ghrayeb himself, and the immunoblot upon which the claim is based is essentially uninterpretable; Ghrayeb Depo. at 271, 348-49; Weiss Decl ¶¶ 13-15; Chang Depo. at 481-88; (8) Putney's notes from his October 20, 1984 discussion with Chang reflect that the clone they discussed number 121 was not one of the two clones upon which the '339 application was based and on which Abbott claims NIH/Centocor was focussed; Putney Notebook at A16796.
Careful review of this competing evidence reveals that it is impossible for this court to determine as a matter of law whether NIH/Centocor successfully reduced the invention to practice prior to Chiron. The conflicting testimony and evidence of the actions taken by NIH/Centocor scientists, including whether they actually had sequenced the env in late August 1984, whether as a result of that sequencing they knew its precise location, and whether they had determined immunoreactivity prior to October 31, as well as the competing interpretations of the import of those actions, constitute the classic genuine dispute of material fact which must be resolved by a jury presented with all of the evidence and with an ability to assess witness credibility. Furthermore, as explained above, there is conflicting evidence in the record as to the precise date Chiron actually reduced the invention to practice.
Accordingly, neither Abbott nor Chiron is entitled to prevail on summary judgment on Abbott's priority defense based on the work performed by NIH/Centocor.
c. The '339 ApplicationAbbott contends that by filing the '339 application on October 10, 1984, NIH/Centocor constructively reduced the invention to practice on that date. The court notes at the outset that while the October 10, 1984 date would not entitle Abbott to summary judgment because it does not beat Chiron's possible late September 1984 date, the court must nonetheless address the merits of this argument, as a jury could reject the September 1984 date and conclude that Chiron did not reduce to practice until its constructive reduction to practice on October 31, 1984.
Pursuant to 35 U.S.C. § 112, for a patent application to constitute a constructive reduction to practice, it must enable one of ordinary skill in the art to make and use the invention, meet the written description test, and set forth the best mode of invention. 35 U.S.C. § 112; see also Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 1560 (Fed.Cir.1991). "That some [further] experimentation is necessary does not constitute a lack of enablement; the amount of experimentation, however, must not be unduly extensive." Amgen, 927 F.2d at 1212 (citing Atlas Powder Co. v. E.I. duPont De Nemours & Co., 750 F.2d 1569, 1576 (Fed.Cir.1984)).
Chiron argues that the '339 application cannot constitute constructive reduction to practice under section 112 because it fails to meet the enablement requirement, fails to provide an adequate written description of the invention, and fails to set forth a best mode.
i. EnablementIn the instant context, in order to meet the enablement requirement, the '339 application must disclose to one of ordinary skill in the art how to make and use recombinant HIV proteins from the env that are immunoreactive with human AIDS serum. Chiron argues that the '339 application fails to meet the enablement requirement because each of its three embodiments (1) requires starting materials that are neither described in the application nor available in the prior art; (2) relies on information about the structure and nucleotide sequence of HIV that was neither disclosed in the application nor available in the prior art; and (3) contains additional fatal flaws.
(a) Starting MaterialThe '339 application sets forth three methods of making recombinant HIV env proteins for diagnostic use. See '339 Application at A4353-59. Of the three embodiments, the first two use as starting material an HIV *1126 "clone," and the third uses as starting material "fragments of [HIV] DNA of approximately 200-500 b[ase]p[airs]." Id.
Chiron argues that the application fails to describe the source or names of, or the process for obtaining, these clones and fragments. Chiron further argues that as of October 10, 1984, there was no method of cloning HIV available in the art, and that Dr. Chang failed to deposit the unnamed clones mentioned in the application with the ATCC. Thus, Chiron concludes that one of ordinary skill in the art attempting to practice the '339 application would be defeated at the outset by an in ability to obtain or produce the necessary starting material. In response, Abbott relies primarily on the undisputed fact that Dr. Gallo and Dr. Wong-Staal had deposited the BH-10 and BH-8 clones with the ATCC by August 22, 1984. In addition, Abbott argues that deposit with the ATCC is unnecessary, and that once HIV had been identified, cloning was merely an application of routine methods already available in the literature. Thus, Abbott concludes that one of ordinary skill in the art attempting to practice the application either could have obtained starting material from the ATCC or simply cloned the starting material based on routine science.
The evidence put forth by both parties with respect to starting material is quite weak. Neither party submits any expert testimony as to the ability of one skilled in the art to practice the invention based on the description of the starting material contained in the '339 application. Instead, both parties ask the court to interpret the application on its face. Ordinarily, in such circumstances the court would find that there is a genuine issue of material fact to be resolved by a jury. However, in the instant context, it is clear to the court that the application fails as a matter of law to set forth sufficient information to enable one of ordinary skill to obtain or make the necessary starting material. First, nowhere in the application are the clones or fragments it references as starting material identified by name. In its papers Abbott refers to the deposit of BH-10 and BH-8 with the ATCC, but neither of those clones is mentioned by name in the application itself; instead, the application uses only generic words like "clone" and "fragment" without more identifying information. Thus, it is undisputed that a scientist would not even know from the application what clones to look for at the ATCC. Further, even if one assumes that cloning was routine in 1984 and there is no expert testimony or other real evidence in the record to this effect[29] it is undisputed by the parties that different clones of HIV vary slightly from one another. Thus, even if cloning HIV was routine, a scientist capable of doing so would not necessarily be able to practice the invention because any particular clone created might not match the clones and fragments referenced in the '339 application.
Accordingly, the court concludes that based on the evidence in the record, no reasonable jury could conclude that the '339 application was a constructive reduction to practice, because the application fails to set forth sufficient information to enable one of ordinary skill to obtain or make the necessary starting material. While this conclusion alone entitles Chiron to summary judgment that the '339 application does not constitute a constructive reduction to practice as a matter of law, the court will address each of the remaining arguments raised by Chiron regarding that application in the interest of thoroughness.
(b) Sequence InformationChiron argues that the '339 application also fails the enablement requirement because it relies on information about the structure and nucleotide sequence of HIV that it does not disclose and which was not available in the prior art. Specifically, Chiron points out that the invention requires that the expressed proteins come from the env region of HIV, and argues that the application contains no accurate description of the nucleotide sequence *1127 or location of the env on the genome. Chiron argues that Figure 3 of the application, which purports to set forth the "nucleotide sequences for [HIV] DNA which encompasses the env region", does not indicate the location of that sequence on the overall genome, nor which portions of it represent the env. Chiron further cites to Dr. Chang's admission that of the 3112 nucleotides set forth in Figure 3, only 883 are from the env, Chang Depo. at 278-80, which itself is actually 2588 nucleotides long, such that Figure 3 sets forth only about one-third of the actual env and fails to distinguish the env nucleotides from non-env nucleotides.[30] Thus, Chiron argues, assuming a scientist could express proteins based on the process described in the application, the application provides that scientist with no basis for determining if the expressed proteins are from the env, which is a critical facet of reducing the invention to practice.
In response, Abbott argues that nucleotide sequences are not necessary for enablement, that the '339 application discloses methods of practicing the invention without sequencing, and that because the one-third of the env for which the application discloses a nucleotide sequence actually contains fragments that are immunoreactive, it does not matter that the application fails to specifically locate the env or set forth its entire sequence. In support of its argument, Abbott offers only the declaration by its putative expert that the portion of the env sequence the application does disclose actually contains three fragments that encode immunoreactive polypeptides. Jack Decl. ¶¶ 7-8.
Once again, although the record is fairly short on evidence for the court to evaluate, Chiron's argument must prevail. This court has held as a matter of law that actual reduction to practice of the instant invention requires the inventor to know that the expressed proteins are from the env, which requires both possession of the nucleotide sequence and identification of the precise location the env. It is undisputed that without such information, a scientist cannot be certain that the expressed proteins are from the env. It also is readily apparent (and essentially undisputed) that obtaining the sequence information would in fact require extensive experimentation indeed, obtaining accurate sequencing of HIV was a major (and complex) feature of all of the various immunoassay projects.
One of ordinary skill in the art attempting to practice the invention described in the '339 application would have no way of knowing for sure whether the expressed proteins were from the env, because the application does not set forth the complete sequence of the env or locate its precise boundaries. While Dr. Jack's testimony that a scientist might actually express a protein from the env using the process set forth in the application is correct, that possibility is irrelevant to enablement because the scientist could not be reasonably certain that it was in fact from the env without extensive further experimentation. Indeed, a scientist who expressed a protein would be misled by Figure 3 into believing it was from the env even if it was not, as that figure purports to set forth the env sequence when in fact most of the nucleotides on it are not from the env.
Accordingly, the court concludes that based on the evidence in the record, no reasonable jury could conclude that the '339 application was a constructive reduction to practice, because the application fails either to set forth a complete nucleotide sequence of the env or to locate its precise boundaries.
(c) Additional Alleged FlawsChiron argues that each of the three embodiments also has additional flaws that preclude the '339 application from constituting constructive reduction to practice.
As to the first embodiment, Chiron argues that none of the fragments identified for use in that embodiment were actually from the env region, such that a scientist practicing that embodiment would not express an env protein. As support for this argument, Chiron cites Dr. Chang's testimony in which she *1128 admits that following the first embodiment literally, a scientist would get "nothing," and that either a crucial sentence was missing from the '339 application or one of the sentences had to be deleted for the first embodiment to work. Chang Depo. at 543-45.
In response, Abbott argues that in fact the first embodiment does enable one of ordinary skill to express immunoreactive polypeptides from the env region. In support of this argument, Abbott cites the declaration testimony of a putative expert, who states that one of ordinary skill practicing the first embodiment would in fact express proteins from the env region of HIV. Jack Decl. ¶¶ 5-8, 10.
Because the parties submit conflicting evidence as to whether one of ordinary skill in the art practicing the first embodiment could express an immunoreactive env polypeptide, there is a classic dispute of material fact which cannot be resolved by the court on summary judgment.
As to the second embodiment, Chiron points out that the random cloning method the '339 employs is based on three DNA fragments, identified in the application as "spanning the env gene." '339 application at A4355. Chiron cites Dr. Chang's concession that of these three fragments, one contains no env, one contains almost no env, and one does not contain all of the env. Chang Depo. at 572-77. Chiron also argues that while a scientist practicing this embodiment could actually express immunoreactive polypeptides from the env, the embodiment fails to provide that scientist a means for distinguishing between env and non-env proteins. Chang Depo. at 590-91; Ghrayeb Depo. at 221-22, 268-69; Weiss Decl. ¶ 11. Chiron finally argues that the second embodiment is not saved by the suggestion that following actual expression of a protein, the scientist must sequence the fragment to ascertain whether it is from the env, because the '339 application does not itself set forth the sequence of the env. Furthermore, knowing the sequence of the fragment alone is not sufficient to determine whether it is from the env. Weiss Decl. ¶ 15; Chang Depo. at 1088; Wong-Staal Depo. at 182-83. In response to this argument, Abbott has offered no evidence or argument with respect to whether the second embodiment is enabling.
Because Abbott has offered no evidence or argument as to whether the second embodiment is enabling, the only evidence in the record reveals that a scientist practicing the second embodiment has no basis for determining whether the proteins expressed pursuant to that embodiment are from the env. Accordingly, Chiron is entitled to summary judgment that the second embodiment is not enabling.
As to the third embodiment, Chiron argues that it wholly fails to describe what its starting material is, and its use of gene-specific DNA probes to locate env proteins fails because for probes to work, the location of the target env or its sequence must be known, and the application fails to set forth either the location or sequence of the env. Weiss Decl. ¶¶ 8-9; Chang Depo. at 552-56. In response, Abbott once again has offered no evidence or argument with respect to whether the third embodiment is enabling.
Because Abbott has offered no evidence or argument as to whether the third embodiment is enabling, the only evidence in the record reveals that despite the description in the third embodiment of gene-specific DNA probes, a scientist practicing the third embodiment nonetheless has no basis for determining whether the proteins expressed pursuant to that embodiment are from the env. Accordingly, Chiron is entitled to summary judgment that the third embodiment is not enabling.
ii. Written DescriptionIn the instant context, in order to meet the written description requirement the '339 application must show that as of the filing date, the putative inventors possessed a means for producing a recombinant clone encoding the env region of HIV that was used to produce an env protein immunoreactive with human AIDS serum. See In re Wertheim, 541 F.2d 257, 262 (C.C.P.A.1976).
Chiron argues that the '339 application fails to satisfy the written description requirement because nothing in the application indicates that NIH/Centocor actually had used a recombinant clone to produce an immunoreactive *1129 env protein. As support for this argument, Chiron cites to the numerous flaws in the application detailed above as evidence that NIH/Centocor could not have successfully practiced the invention themselves at the time of the application. In response, Abbott once again raises no argument and offers no evidence to counter Chiron's contention.
While Abbott has not cited any evidence in response to Chiron's argument, the court nonetheless cannot grant Chiron summary judgment on this issue. The court has held, in section II.B.3.b above, that a jury must determine when NIH/Centocor actually reduced the invention to practice. Accordingly, despite the flaws in the '339 application detailed above, and Abbott's failure to address this argument head on, the court simply cannot say as a matter of law that NIH/Centocor was not in possession of the invention on October 10, 1984 when it filed the '339 application.
iii. Best ModeThe best mode rule requires an inventor to set forth in a patent application the best mode known to the applicant for practicing the invention. The purpose of this requirement is to prevent the inventor from obtaining patent protection without actually having to set forth a means for its successful practice. See Advanced Cardiovascular Sys., Inc. v. Scimed Life Sys., Inc., 20 U.S.P.Q.2d 1791, 1793, 783 F. Supp. 413 (D.Minn.1991). An act of concealment violates the best mode rule. Engel Indus. Inc. v. Lockformer Co., 946 F.2d 1528, 1531 (Fed. Cir.1991).
Chiron argues that the '339 application violates the best mode rule because it fails to set forth an enabling description of the necessary starting materials despite the fact that its inventors had possession of that information. In support of this argument, Chiron cites the evidence this court found persuasive above, namely, that the application does not set forth adequate information for obtaining or making the necessary starting material. In addition, Chiron points to evidence in the record that no later than August 1984, Dr. Gallo and Dr. Wong-Staal, two of the putative inventors, knew how to clone HIV, but failed to include this information in the application. See Krevans Decl. Ex. 4, Hahn et al., Molecular Cloning and Characterization of the HTLV-III Virus Associated with AIDS, 312 Nature 166 (1984); Joint Statement ¶ 60 (Gallo and Wong-Staal filed the '306 application on August 22, 1984, setting forth "the process for molecularly cloning the complete genome of the HTLV-III virus."). Chiron argues that the failure to disclose this information in the application constitutes concealment, and thus violates the best mode rule. In response to this argument, Abbott has once again stood mute.
The only evidence in the record is that NIH/Centocor possessed the means for obtaining the necessary starting material to practice the invention, but failed to disclose that information in the '339 application. The court concludes as a matter of law that this failure constitutes concealment and thus violates the best mode rule. Accordingly, the court holds that no reasonable jury could conclude that the '339 application was a constructive reduction to practice because the application fails to set forth a best mode.[31]
d. DuPontAbbott finally argues that DuPont also conceived of the invention under the traditional standard prior to Chiron and then diligently reduced it to practice on December 28, 1984. Specifically, Abbott argues that DuPont successfully sequenced the entire env region of HIV and located its precise boundaries by September 1, 1984, that it expressed env proteins in late November 1984, and that those proteins proved immunoreactive on December 28, 1984.
Because the court has followed the Federal Circuit in holding that conception of the instant invention did not occur until there was actual reduction to practice, Abbott's contention that DuPont conceived of the invention under the traditional standard prior to Chiron and then diligently reduced it to practice *1130 misses the mark. In all of the voluminous briefing and argument on this motion, both oral and written, Abbott has never argued (or offered any evidence) that DuPont actually reduced the invention to practice prior to Chiron it's sole contention with respect to DuPont is that it diligently reduced the invention to practice after having traditional conception prior to Chiron. There is no evidence in the record that DuPont satisfied the hybrid-conception requirement prior to Chiron. Therefore, Abbott's argument regarding DuPont's diligent reduction to practice is unavailing. Indeed, Abbott itself repeatedly asserts that it "is undisputed" that DuPont actually reduced the invention to practice in late December 1984, well after October 31, 1984.
While it is true that the precise date of Chiron's reduction to practice (actual or constructive) necessarily remains an open question, the court cannot and will not make arguments or posit theories on behalf of Abbott that it has chosen not to make. Because Abbott has never argued or offered evidence that DuPont actually reduced the invention to practice prior to Chiron, it cannot proceed upon that theory to support its priority defense. Accordingly, Chiron is entitled to summary judgment on Abbott's priority defense based on DuPont's work.
C. SummaryFor the reasons set forth above, the court concludes that conception of the instant invention occurred only with hybrid conception conception plus actual reduction to practice and that actual reduction to practice required expression of recombinant proteins known to be from the env region of HIV that were immunoreactive with HIV-infected sera. Neither party is entitled to prevail on summary judgment on Abbott's prior invention defense. Chiron is entitled to proceed upon its contention, but not itself entitled to summary judgment, that it actually reduced the invention to practice as early as late September 1984, and that it constructively reduced the invention to practice on October 31, 1984. Abbott is entitled to proceed upon its argument, but not itself entitled to summary judgment, that NIH/Centocor actually reduced the invention to practice prior to Chiron, but it cannot as a matter of law proceed upon its argument that the '339 application constituted constructive reduction to practice. Chiron is entitled to summary judgment that Abbott cannot proceed upon its theory that DuPont actually reduced the invention to practice prior to Chiron.
CONCLUSIONFor the foregoing reasons, IT IS HEREBY ORDERED that:
(1) Abbott's motion for summary judgment on its inequitable conduct defense is DENIED;
(2) Chiron's motion for summary judgment on Abbott's inequitable conduct defense is DENIED in part and GRANTED in part, as set forth above;
(3) Abbott's motion for summary judgment on its prior invention defense is DENIED;
(4) Chiron's motion for summary judgment on Abbott's prior invention defense is DENIED in part and GRANTED in part, as set forth above;
(5) Because of the numerous opportunities the parties have had to argue and brief the issues involved in these motions, the court will entertain no motions to reconsider this order.
IT IS SO ORDERED.
NOTES[1] The court issued a tentative memorandum and order on May 31, 1995, and oral argument was held on that order on June 9, 1995. Per the court's instructions at that hearing, the parties have submitted supplemental briefing and made supplemental evidentiary submissions, all of which have been taken under submission along with the original briefing and evidence. The court has found that issuing a tentative order and having the parties focus on that order at oral argument and file supplemental briefing has been extremely useful, and is a practice worth repeating in similar cases. With issuance of this order, the court's tentative order is vacated and withdrawn.
[2] All facts in this section are derived from the Joint Statement of Undisputed Facts submitted by the parties and other undisputed portions of the record. In its supplemental briefing on the tentative order, Chiron challenges a number of the facts recited in this section. Chiron's challenges must fail. The facts in this section are those to which Chiron stipulated in the joint statement, and it cannot now attempt to disavow facts to which it has stipulated.
[3] In the early years of AIDS research, the virus was known by several acronyms, including the current HIV as well as HTLV-III and LAV, among others. For the sake of consistency and simplicity, the court employs the acronym HIV, except where otherwise necessitated by the record.
[4] Actually, because its genetic material is RNA rather than DNA, HIV is a retrovirus.
[5] The ATCC is a depository for living material, and deposition there is necessary for carrying out claimed inventions involving living material.
[6] In May 1986, Centocor asked the PTO to amend the inventorship of the '866 application to include Dr. Gallo and Dr. Wong-Staal.
[7] A series of patent applications led to the '949 patent. The history of the patent prosecution is as follows: (1) Application No. 06/667,501 filed 10/31/84, abandoned 7/14/86; (2) Application No. 06/696,534 filed 1/30/85, abandoned 7/14/86; (3) Application No. 06/773,447 filed 9/6/85, abandoned 9/12/88; (4) Application No. 07/138,894 filed 12/24/87, granted as '949 patent.
[8] It is undisputed that these claims subsequently became claims 1-22 in the '949 patent as issued.
[9] Chiron expends considerable effort arguing that the issues listed on the interview report were not those upon which agreement was not reached, but only those issues that were discussed. While this interpretation of the report is plausible, it is not obvious on the face of the document that this necessarily is the case, and the fact that Steimer subsequently submitted a Rule 132 declaration discussing the key issue listed there certainly is evidence that the issue had yet to be resolved.
[10] Chiron references a February 20, 1990 interview with the examiner, but it appears that it was referring to the February 14, 1990 interview, the notice of which was mailed on February 20.
[11] In its supplemental citations, Chiron points to two previous submissions to the PTO that addressed this problem. See Goolkasian Supp. Decl.Ex. A (Haigwood Decl.) ¶ 5, Ex. D (Chiron's January 1990 Amendment) at 9-17. However, each of these documents was submitted prior to the February 1990 interview, after which the issue apparently remained open notwithstanding those submissions. Indeed, Chiron itself concedes that the Steimer Declaration "provided additional citations to scientific articles discussing the heterogeneity of HIV, while reiterating the same point made by Dr. Haigwood and in Chiron's January 1990 Amendment." Chiron's Additional Citations at ¶ 14. Chiron offers no explanation why further citations and reiteration was necessary after the interview if the issue already was resolved. These prior submissions do not alter the fact that other than the Steimer Declaration, nothing in the post-interview record relates directly to the critical issue.
[12] Furthermore, a second notice went out on April 27, 1992, correcting the inventorship as a result of the September 21, 1990 submissions. The fact that Nucker considered the amended notice of inventorship in the September 1990 supplemental response further raises the possibility that she also considered the Steimer Declaration, which was part of the same submission.
[13] In a declaration filed with the PTO as part of the Essex interference, Chiron scientist Stella Quan explained that the HAV project failed in the period 1985-1987. Goolkasian Supp. Decl.Ex.B. This evidence of good faith would make it impossible for Abbott to demonstrate by clear and convincing evidence that Chiron had the necessary intent to deceive the PTO as to the HAV project.
[14] Chiron's putative expert states only that in his opinion the HBV and FeLV projects were not more relevant than the HAV project, and that they would have been cumulative. Goolkasian Supp.Decl. ¶ 30. Nowhere does he state, however, that such work was irrelevant, or that reporting the HAV failure without the HBV success gave an accurate impression of the state of the art in 1984.
[15] Chiron's reliance on the fact that it had not developed a commercial HBV kit is irrelevant, as the issue is not the marketing of such a kit but the success of the HBV project and its relevance to the HIV work. Furthermore, Chiron's reliance on the fact that its HBV project was based on "core" proteins, not "surface" proteins like those sought in the HIV work also is irrelevant. The point is not that the HBV project was identical to the HIV work, but that Chiron had successfully produced recombinant HBV proteins, that it represented that success to the government as relevant to the HIV work, and that it failed to report that success to the PTO. Furthermore, Dr. Luciw testified that Chiron was working with surface HBV antigens as well, though he could not recall the specifics, and that it was this work that led him to believe that a recombinant HIV immunoassay would work. Luciw Depo. at 142-44, 146. Chiron also erroneously relies on the fact that there is no evidence from its HBV project that a recombinant antigen would be "as effective" as a natural one. Again, this is irrelevant. The omission of the HBV project does not become non-material simply because that project does not show that recombinant assays are as effective as native assays. Its materiality is based on the fact that Chiron had successfully produced recombinant HBV proteins for use in an assay, and believed itself (and represented to the government) that such success was relevant to the HIV work.
Finally, Chiron's contention that Dr. Steimer was personally unaware of the HBV work at the time of her declaration is disingenuous. Citing Dr. Steimer's deposition testimony, Chiron argues that it is undisputed that Steimer "had no knowledge of Chiron's HBV work." Chiron's Further Submission Re: Inequitable Conduct at 6 (citing Steimer Depo. at 513-14). Careful review of Steimer's deposition reveals that Chiron has mischaracterized her testimony. Steimer was not asked, and did not testify, that she had no knowledge of Chiron's HBV work. In fact, the following colloquy took place:
Q: ... [a]re you aware of any hepatitis B recombinant-based immunoassay, whether it involves surface antigens ... or some other recombinant proteins?
A: It is possible that and I don't know exactly where this effort is but I was trying to recall after our discussion yesterday what it was I knew about hepatitis B diagnostics at Chiron, and I recalled that, in fact, I believe there is a need to that that looking for antibodies to core is considered an important component of diagnostic diagnosis of chronic hepatitis B. And I recall that Chiron was doing some work trying to develop hepatitis B core antigens, core antibody assay. And I am not positive whether we were trying to use recombinant antigen in that format or not. That's really all I can recall at this time....
Steimer Depo. at 514. Thus, while it is clear Steimer was not necessarily aware of all of the details of the HBV work, she has admitted to being aware that such work was going on at Chiron, and a reasonable factfinder could conclude that her failure to report it to the PTO was purposefully misleading.
[16] In its tentative order, the court based its conclusion that omission of the FeLV work was not material on the fact that the FeLV work involved a vaccine, not an immunoassay. However, as Abbott's supplemental briefing and evidentiary submissions make clear, that fact is not dispositive. The evidence reveals that in its attempt to create a vaccine, Chiron created recombinant FeLV env antigens and determined their reactivity with antibodies to the virus a process essentially identical to that employed in creating a recombinant immunoassay. Thus, the court is persuaded that its conclusion regarding the FeLV work in the tentative order was erroneous.
[17] Chiron again erroneously relies on the fact that there is no evidence from its FeLV project that a recombinant antigen would be "as effective" as a natural one. Again, this is irrelevant. As with the HBV project, the omission of the FeLV project does not become non-material simply because that project does not show that recombinant assays are as effective as native assays. Its materiality is based on the fact that Chiron had successfully produced recombinant FeLV proteins that proved immunoreactive, and believed itself (and represented to the government) that such success was relevant to the HIV work.
[18] This rule is sometimes referred to as the "first to conceive, last to reduce to practice" rule.
[19] Of course, Chiron is entitled to show that it actually conceived of and reduced the invention to practice prior to that date in order to defeat alleged prior inventors.
[20] Abbott also alludes to other possible prior inventors, including, apparently, Genentech. However, Abbott has failed to submit any evidence as to any other putative prior inventors.
[21] At oral argument and in supplemental briefing, Chiron essentially abandoned this contention altogether.
[22] Chiron further argues that creation of a restriction map was unnecessary for purposes of conception, because it is just a predictable, mechanical step that anyone of ordinary skill could perform.
[23] The court notes that while hybrid conception of the instant invention is equivalent to actual reduction to practice, it would constitute only a first step toward constructive reduction to practice (via a patent application), which of course has additional requirements such as enablement and best mode. See 35 U.S.C. § 112; Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 1560 (Fed.Cir. 1991).
[24] It is undisputed that it is sequencing, not the creation of restriction maps, that enables scientists to create a complete map of the exact order of the nucleotides comprising the DNA and to accurately locate sections of the genome such as the env.
[25] In its tentative order, this court held that possession of a restriction map was a prerequisite to conception, and knowledge of the nucleotide sequence was not. The court is now persuaded that that conclusion was erroneous. As set forth above, the Amgen/Burroughs Wellcome line of cases clearly establish that in the context of genetic compounds, sequencing is a prerequisite to conception, and conception is not complete until there is actual reduction to practice. That holding comports with the evidence in the instant record. There is undisputed testimony in the record that while it is true that a protein can be expressed by one of ordinary skill in the art without having the benefit of any sequencing information once a DNA fragment is defined by its restriction sites, see Ghrayeb Depo. at 433-38; Putney Depo. at 34, 50-51; Dina Depo. at 494; 500-01; Luciw Depo. at 439-40, it also is true that without the sequencing information, the inventor cannot be sure that the fragment is from the desired region of the protein, Putney Depo. at 34-35; Dina Depo. at 494; Luciw Depo. at 440-41; Chang Depo. at 1088; Weiss Decl. ¶ 15; Wong-Staal Depo. at 182-83, and thus, under Amgen, cannot have conception. Simply possessing a restriction map and expressing a protein on that basis does not tell the inventor that he has expressed the protein he desires to express only sequencing can provide that crucial information.
[26] As this court has held above, under the hybrid-conception doctrine, Chiron completed one aspect of constructive reduction to practice by filing a patent application. There remain further elements of the doctrine of constructive reduction to practice. These additional elements are the subject of a second round of scheduled motions in which Abbott argues, inter alia, that the '949 patent is invalid because it fails to enable one of ordinary skill in the art to practice the invention. However, Abbott has not disputed that by the date it filed its patent application, Chiron had achieved hybrid conception of the instant invention.
[27] Abbott is entitled to argue and does so in the next round of scheduled motions that the patent ultimately issued on the October 31, 1984 application was not enabling, which would mean that it cannot constitute a constructive reduction to practice. Because the issue of whether the October 31 application is enabling is not properly before the court on this motion, the court cannot resolve it.
[28] Because the court has held that conception of the instant invention requires actual reduction to practice, Abbott's argument regarding NIH/Centocor's prior conception under the traditional standard and diligent reduction to practice is irrelevant and will not be addressed.
[29] In support of its argument that cloning of HIV was routine in 1984, Abbott cites a single article from 1982 describing the cloning of the HTLV-1 virus. See Abbott Ex. 8K. There is no evidence in the record, however, and Abbott cites none, to suggest that the mere fact that scientists had determined how to clone one retrovirus means that cloning of a different retrovirus therefore was routine.
[30] Chiron also points out that the first publication of the sequence information for the NIH clones was in the January 24, 1985 article entitled Complete Nucleotide Sequence of the AIDS Virus, HTLV-III, 313 Nature 277 (1985), which was not submitted for publication until November 29, 1984 by Dr. Chang and others at NIH/Centocor.
[31] The court notes, without drawing any conclusions, that the '339 application is still pending before the PTO. Nothing in the record explains why no decision has been reached on the application.
