White Papers & Patents

Steve Hutt - Three Goals when Publishing Papers:

When I write papers my goals are;

1. Learn. Writing a paper requires extensive, rigorous research and discipline. Each of my published papers began with research into areas where I was a 'neophyte' requiring deeper knowledge. How can you not learn by writing?

2. Teach. Try to teach enough to guide a 'novice' reader but not enough to empower a 'worthy' competitor.

3. Promote. Let's face it, we're promoting our selves, our companies our philosophies.
