By: Peter J. KarolToo often the catch-all term “intellectual property”— useful in describing practitioner specialty areas, law school courses, and text books, among other things— serves a subtly insidious function. It suggests that those discrete bodies of law which it encompasses—roughly, copyright, trademark, patent, and trade secret law—have fundamental commonality. Not only, it implies, do those legal areas overlap, but more critically that those overlaps somehow count for more than any divergences. This has a real effect on the development of the law. Courts are quick to presume that a rule applicable to one area of intellectual property ought to apply to all. The burden, it seems, is on one challenging such an extension to show why a given area of law, say trademark law, is distinct enough from another, such as patent law, so that a rule for one should not apply to another. The courts, for instance, over the past decade worked to extend a rule from a 2006 patent case that denies prevailing patent infringement plaintiffs entitlement to injunctive relief (eBay Inc v. MercExchange) to copyright and trademark law. We are now seeing that process inexorably repeat itself with respect to statutory fee-shifting.
