Nitride Semiconductors files complaint against Lite-On Technology
Nitride Semiconductors has announced that it has successfully filed a complaint against Lite-On Technology Corporation and its 3 U.S.-based affiliated companies (collectively, "Lite-On"), in the U.S. District Court for the Western District of Texas, Waco Division, asserting infringement of Nitride’s UV LED patent.
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.
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 ("Rayvio") 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.
Further, the lawsuit which Nitride has filed against Digi-Key Corporation ("Digikey"), a global electrical components distributor, is pending before the U.S. District Court for the District of Minnesota. Nitride is asserting that UV LED products being supplied by various LED companies - such as American Opto Plus LED Corp., Crystal IS Inc., Lite-On Semiconductor Corp, Luminus Devices Inc., Kingbright Electronic Co., Ltd., QT-Brightek Corp. and Vishay Intertechnology Inc. - have been infringing Nitride's UV LED patent.
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.
Secure Your Hydrogen Supply
A study supply of high-purity hydrogen is critical to semiconductor fabrication. Supply chain interruptions are challenging manufacturers, leading to production slowdowns and stoppages. On-site hydrogen generation offers a scalable alternative for new and existing fabs, freeing the operator from dependence on delivered gas.Plant managers understand the critical role that hydrogen plays in semiconductor fabrication. That important job includes crystal growth, carrier gas, wafer annealing, and in the emerging Extreme UV Lithography (EUV) that will enable new generations of devices. As the vast need for semiconductors grows across all sectors of world economies, so does the need for high-purity hydrogen.
