CAFC Reverses and Vacates Decision for L’Oréal, Finding District Court Claim Construction was Improper
On June 13, the U.S. Court of Appeals for the Federal Circuit (CAFC) reversed in part, vacated in part, and remanded a decision by the United States District Court for the District of Delaware relating to the University of Massachusetts’ (UMass’) suit against L’Oréal S.A. and its American subsidiary L’Oréal USA, Inc. (collectively, L’Oréal), alleging patent infringement of both U.S Patent No. 6,423,327 (the ‘327 patent) and U.S. Patent No. 6,645,513 (the ‘513 patent). The district court held that it lacked personal jurisdiction over L’Oréal S.A. and that the patents were invalid based on indefiniteness. UMass on appeal challenged both of the district court’s holdings, arguing that they were entitled to jurisdictional discovery against L’Oréal S.A. and that the claim construction performed by the district court was improper.
