Nichia Corporation (“Nichia”) sued Everlight Americas, Inc., Everlight Electronics Co., Ltd. and Zenaro Lighting (collectively, “Everlight”) for infringement of three of Nichia’s patents disclosing packaging designs and methods of manufacturing LED devices. Following a bench trial, the district court found that Everlight infringed all three patents and failed to prove the patents invalid. The district court denied Nichia’s request for a permanent injunction. Nichia appealed the district court’s refusal to enter a permanent injunction, and Everlight cross-appealed the district court’s infringement and validity findings. The Court affirmed on all grounds.
