Nitride files UV-LED patent infringement lawsuit
Japanese UV-LED firmÂ Nitride Semiconductor has filed a patent infringement lawsuit with the US District Court, Northern District of California against Rayvio, a California 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.Â Â
The patented invention is said to significantly contribute to improvements in LED light emitting efficacy.
With Shiro Sakai at Tokushima University, Nitride succeeded in developing a highly efficient UV-LED in 2000, and has continued to manufacture and sell UV-LED since then.Â Nitride says it has made a huge investment in R&D to develop and modify UV-LED, which has been quite challenging.
