The Medimmune Decision

In <i>MedImmune v. Genentech</i>, decided Jan. 9, 2007, the U.S. Supreme Court swept away over a decade of Federal Circuit precedent to find that a licensee need not breach a patent license in order to file a declaratory judgment action for patent invalidity or unenforceability. The decision shifted substantial power from licensors to licensees: previously, a licensee had to choose the lesser of two evils. On one hand, the licensee could comply with the terms of a license agreement and forego any challenge to a patent, even if it felt the patent was not infringed, invalid, or unenforceable. On the other hand, the licensee could breach the license and challenge infringement, validity, and enforceability; in doing so, however, it exposed itself to potentially trebled damages and attorney's fees under 35 U.S.C. '' 284 &amp; 285 and an injunction against future sales under 35 U.S.C. ' 283 if its challenge failed.
