Seoul Semi wins high-power LED patent lawsuit in Germany
South Korean LED maker Seoul Semiconductor Co Ltd has announced another victory in a patent infringement lawsuit against a global electronic components distributor of high-power LEDs in Germany. This continues Seoul’s record of successes in patent litigation.
In October, the Düsseldorf Court issued a preliminary injunction for infringement of Seoul’s patent against various LEDs manufactured by Luminus Devices Inc and Lite-On Inc, and distributed by Mouser Electronics Inc.
Lite-On, which manufactured LEDs subject to the injunction, was also sued for patent infringement in the USA in April 2021 by Seoul’s affiliate Sensor Electronic Technology Inc (SETi). Nitride Semiconductors Co Ltd and Nitek Inc have also filed patent infringement lawsuits against Lite-On in US courts.
Seoul and its affiliates say they have prioritized patent enforcement against companies that have refused to take responsibility for selling infringing products, including Seoul’s prior litigation against Enplas Corp and Everlight Electronics Co Ltd.
In the past four years, Seoul has secured eight injunctions in Europe against the sale of infringing products, including cell phones, electronic home appliances, and general lighting products.
