On Wednesday, April 25th, the Court of Appeals for the Federal Circuit issued a precedential decision in Gilead Sciences v. Merck & Co. et. al., which affirmed a lower court’s ruling that Merck could not assert claims from two patents against Gilead because Merck had unclean hands regarding the patents. The case, coming out of the Northern District of California, involves patents covering methods for effectively treating the hepatitis C virus (HCV)… Reviewing the facts of the case, the Federal Circuit panel found sufficient evidence supporting the district court’s findings of serious business misconduct by Merck, that Merck’s misconduct was related to the litigation and that litigation misconduct had occurred based on false testimony provided by Merck’s non-firewalled patent lawyer, who had originally testified that he was not a party to the March 2004 phone call with Pharmasset.
