Seoul Semiconductor withdraws lawsuit after Mouser stops selling Everlight LED product in Japan
South Korean LED maker Seoul Semiconductor Co Ltd has concluded a patent infringement lawsuit seeking an injunction on the sale by global electronic components distributor Mouser Electronics Inc of an LED product manufactured by Taiwan-based Everlight Electronics Co Ltd.
In February 2018, Seoul filed a patent infringement lawsuit with the Tokyo District Court, accusing the LED product made by Everlight and sold by Mouser of infringing an LED patent of Seoul’s affiliate. Mouser has agreed not to export the accused Everlight LED product in Japan, and Seoul has therefore agreed to withdraw the lawsuit.
The patented technology involved serves to efficiently extract light emitted from the internal LED structure by attaching a light-reflection structure to the LED chip, increasing light extraction efficiency significantly.
Seoul says it has established hundreds of patents arising from this patented technology, which covers an LED module, package, chip and epitaxial structure. The patented technology has been widely applied to mid-power LED products, such as lighting, automobiles and mobile phones, with power consumption of less than 1W.
Seoul has already obtained an injunction against certain Everlight LED products in Germany. In December, the District Court of Düsseldorf rendered judgments in favor of Seoul Semiconductor’s infringement claims, including ordering an injunction against sales of the accused Everlight products. The court also ordered the recall of the accused Everlight products sold after 13 July 2012 from the distributor’s commercial customers.
“To create a fair competition market, we will continue enforcement efforts to prevent manufacturers and distributors from selling suspected infringing products,” says Nam Ki-bum, sales & marketing executive VP at Seoul.
