Nitride Semiconductor Previously Filed Lawsuit Against RayVio
In addition to this latest infringement action on May 23, 2017, Nitride Semiconductor previously filed an application for an injunction in the United States District Court for the Northern District of California, USA, alleging that RayVio’s UV-LED products infringed its patent.
Nitride Semiconductor claims that it worked with professor Shiro Sakai of the University of Tokushima to develop the first high-efficiency UV-LED in 2000. Since that time, the company says it has served as a UV-LED pioneering company that both manufactures and sells UV-LED products. Also, Nitride says it has invested significantly in research and development to improve UV-LEDs.
