Nitride Semiconductor wins UV LED patent lawsuits in USA against RayVio

Nitride Semiconductor Co Ltd of Tokushima, Japan says that it has won a patent infringement lawsuit against RayVio Corp of Haywood, CA, USA, which is commercializing deep-ultraviolet (UV) LEDs and consumer disinfection solutions for health and hygiene applications.

On 13 January, the California Northern District federal court issued a judgment declaring that RayVio had infringed Nitride Semiconductor’s patent and that the asserted claims of Nitride’s patent are not invalid.

A month ago, the US Patent Office also confirmed the validity of the key claims of Nitride’s patent in its final judgments of the Inter Parte Review case filed by RayVio.

Together with professor Shiro Sakai at Tokushima University, in 2000 Nitride Semiconductor developed what it claims were the first highly efficient UV-LEDs, and it has since continued to manufacture and sell UV-LED, involving huge investment in R&D.

Nitride Semiconductor says that it regards its intellectual property rights as vitally important assets, and it will accordingly take resolute actions against infringers in any country where appropriate and necessary to protect its patents and other intellectual property rights.
