Late last month, Nitride Semiconductors Co., Ltd. sued Digi-Key Electronics (0:21-cv-00437), again, and Lite-On (6:21-cv-00183), for the first time, over a single patent that Nitride describes as generally related to “ultraviolet (‘UV’) light-emitting diode (‘LED’) technology”. In the Lite-On complaint, the plaintiff directly targets Lite-On’s provision of “[aluminum gallium nitride] AlGAN-based UV LEDs or products containing such LEDs”, while the second Digi-Key complaint adds to the list of accused products allegedly sold by that defendant but made by others, now including American Opto Plus LED, Crystal IS, Kingbright Electronic, and QT Brightek (all named in the February 2021 complaint), as well as Innolux, Lite-On, Luminus Devices, RayVio, and Vishay Intertechnology (all named in an amended complaint filed in the original Digi-Key suit).
