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

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.

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.
