Nitride Filed Patent Infringement Lawsuit against Rayvio in CA regarding Rayvio’s UV-LED Products

On May 23, 2017 (PDT), Nitride Semiconductor Co., Ltd. (“Nitride”) filed a patent infringement lawsuit with the U.S. District Court, Northern District of California against Rayvio Corporation (“Rayvio”), a CA-based UV-LED manufacturer. In the complaint, Nitride is seeking injunction, damages and accounting, asserting that Rayvio infringes Nitride’s patent (US 6,861,270, “Method for Manufacturing Gallium Nitride Compound Semiconductor and Light Emitting Element”) by manufacturing its products. The patented invention significantly contributes to improvement for LED’s light emitting efficacy.


Nitride is a pioneer in the field of UV-LED. With Professor Shiro Sakai at Tokushima University, Nitride succeeded in development of highly efficient UV-LED in 2000 for the first time in the world, and has continued to manufacture and sell UV-LED thereafter. Nitride has made a huge investment in R&D to develop and modify UV-LED, which has been quite challenging.


Nitride places its intellectual property rights as its vitally important management assets. Accordingly, Nitride will take resolute actions to against infringers in any country where appropriate and necessary to protect its patents and other intellectual property rights.
