According to the amended complaint, Nitride Semiconductor claimed that UV LED products being supplied by various LED companies including Lite-On Semiconductor, Luminus Devices, and Vishay Intertechnology are infringing Nitride’s UV LED patent.

To protect its UV LED patented technology, Nitride initiated its patent enforcement campaign starting in 2017. By virtue of such efforts, a judgment was issued out of the U.S. District Court for the Northern District of California in favor of Nitride and against RayVio Corporation in 2020, who infringed Nitride’s UV LED patent. That judgment was also in Nitride’s favor with respect to the validity of its patent. The U.S. Patent & Trademark Office has also confirmed the validity of the key claims of Nitride’s patent in its final judgment on an Inter Parte Review case filed by RayVio.
