2008 Berkeley Patent Survey
The 2008 Berkeley Patent Survey showed that venture capitalists are not interested in software patents and that SMEs over estimate the importance of having patents. The paper was published in the USA by Robert Merges, Pamela Samuelson, Ted Sichelman, and Stuart Graham.
 Major findings
In a three-part series, authors Merges, Samuelson, and Sichelman highlighted key findings.
The study found that while 97% of venture-backed startups in biotech have patents, only 67% of venture-backed software startups do, and among all software startups (regardless of their source of financial backing) the number drops to 25%. This information was used in EFF's Bilski v. Kappos brief.
From an article written by two of the authors:
Among software companies, the results are even more striking, with them reporting that patents provide less than a "slight" incentive.
