Trademark owners regularly rely on claims that the defendant is "free riding" on their mark by making money using that mark, money the trademark owners say should belong to them. We analyze those free-riding claims and find them wanting. The empirical data shows that defendants in unrelated markets can benefit from using a well-known mark, but that neither mark owners nor consumers suffer any injury from that use.

Patenting By Entrepreneurs: An Empirical Study, Ted Sichelman, Stuart J.H. Graham

Michigan Telecommunications & Technology Law Review

[T]he Ewing Marion Kauffman Foundation--an organization that studies and promotes entrepreneurship in the United States--funded an effort at the University of California, Berkeley School of Law, to undertake the first comprehensive survey of the relationship between patenting and entrepreneurship in the United States. The authors, along with other investigators, administered the survey in 2008 to approximately 15,000 startup and early-stage companies in the biotechnology, medical device, information technology (IT) hardware, and software and Internet sectors. A portion of the survey examined why entrepreneurs, startups, and early-stage companies do (and do not) seek patents. This Article reports and analyzes results from …
