In the complaint, Nitride is asserting that UV LED products being supplied by various LED companies – such as American Opto Plus LED Corp., Crystal IS Inc., Kingbright Electronic Co., Ltd., and QT-Brightek Corp. – have been infringing Nitride’s UV LED patent. In an earlier-filed patent litigation against Digikey, Nitride has already accused patent infringement against UV LED products of Luminus Device Inc. and Lite-On Semiconductor Corp.
Nitride is one of the earliest ground breakers in the field of UV-LEDs. With Professor Emeritus Shiro SAKAI at Tokushima University, Nitride succeeded in developing highly efficient UV-LEDs as early as 2000. This was the first time in the world such a breakthrough in UV LED technology had been achieved. Nitride has continued to manufacture and sell UV-LEDs thereafter, and has invested enormously in R&D to develop and enhance its UV-LED technology.
Nitride considers its intellectual property rights to be vitally important company assets. Accordingly, Nitride will take any and all action necessary to enforce its patent against infringers in any country and uphold its patents and other intellectual property rights.
