Competition And Congestion In Trademark Law, Christopher Buccafusco, Jonathan S. Masur, Mark P. Mckenna

Faculty Scholarship

Trademark law exists to promote competition. If consumers know which companies make which products, they can more easily find the products they actually want to purchase. Trademark law has long treated “source significance”—the fact that a particular trademark is identified with a particular producer—as both necessary and sufficient for establishing a valid trademark. That is, trademark law has traditionally viewed source significance as the only necessary precondition for a trademark being pro-competitive. In this Article, we argue that this equation of source significance and pro-competitiveness is misguided. Some marks use words that are so closely connected with the product being …

Mark Of The Devil: The University As Brand Bully, James Boyle, Jennifer Jenkins

Faculty Scholarship

In recent years, universities have been accused in news stories of becoming “trademark bullies,” entities that use their trademarks to harass and intimidate beyond what the law can reasonably be interpreted to allow. Universities have also intensified efforts to gain expansive new marks. The Ohio State University’s attempt to trademark the word “the” is probably the most notorious. There has also been criticism of universities’ attempts to use their trademarks to police clearly legal speech about their activities. But beyond provocative anecdotes, how can one assess whether a particular university is truly bullying, since there are entirely legitimate reasons for …

Fashion's Function In Intellectual Property Law, Christopher Buccafusco, Jeanne C. Fromer

Faculty Scholarship

Clothing designs can be beautiful. But they are also functional. Fashion’s dual nature sits uneasily in intellectual property law, and its treatment by copyright, trademark, and design patent laws has often been perplexing. Much of this difficulty arises from an unclear under-standing of the nature of functionality in fashion design. This Article proposes a robust account of fashion’s function. It argues that aspects of garment designs are functional not only when they affect the physical or technological performance of a garment but also when they affect the perception of the wearer’s body. Generally, clothes are not designed or chosen simply …

Functionality Screens, Christopher Buccafusco, Mark A. Lemley

Faculty Scholarship

Among intellectual property (IP) doctrines, only utility patents should protect function. Utility patents offer strong rights that place constraints on competition, but they only arise when inventors can demonstrate substantial novelty after a costly examination. Copyrights, trademarks, and design patents are much easier to obtain than utility patents, and they often last much longer. Accordingly, to prevent claimants from obtaining “backdoor patents,” the other IP doctrines must screen out functionality. As yet, however, courts and scholars have paid little systematic attention to the ways in which these functionality screens operate across and within IP law.

We have four tasks in …

Testing Tarnishment In Trademark And Copyright Law: The Effect Of Pornographic Versions Of Protected Marks And Works, Christopher Buccafusco, Paul J. Heald, Wen Bu

Faculty Scholarship

Federal and state law both provide a cause of action against inappropriate and unauthorized uses that ‘tarnish’ a trademark. Copyright owners also articulate fears of ‘tarnishing’ uses of their works in their arguments against fair use and for copyright term extension. The validity of these concerns rests on an empirically testable hypothesis about how consumers respond to inappropriate unauthorized uses of works. In particular, the tarnishment hypothesis assumes that consumers who are exposed to inappropriate uses of a work will find the tarnished work less valuable afterwards. This Article presents two experimental tests of the tarnishment hypothesis, focusing on unauthorized …
