New files for utility patents

Post date: Aug 5, 2010 7:21:33 PM

The file formerly known as pat76_06_pdp has now been revised into two files: pat76_06_assg has one record for every assignment of every utility patent from 1976-2006 (multiple records when there are multiple assignees) and pat76_06_ipc has one record for every IPC class of each patent. See the documentation on the download page for details.
