Seoul Semiconductor has filed a patent infringement lawsuit in the United States District Court for the District of New Jersey against an automotive component distributer Onyx Enterprise International.

According to Seoul Semiconductor, Onyx distributes various automotive LED lights on its online platform “CARiD.com,” which offers car parts and accessories covering automotive headlamps, tail lights and fog lights.

The Korean company claimed that automotive LED products being sold on “CARiD.com” infringe 12 patents – including Seoul’s WICOP (Wafer Level Integrated Chip On PCB) technology, a revolutionary technology co-developed with its subsidiary, Seoul Viosys.

WICOP technology enables LED chips to be soldered to a PCB without lead-frames or gold wires, which enhances heat dissipation and fitness for LED lenses. The technology has been adopted a wide range of applications including automotive lighting, display backlight products, smart phone flash LEDs, and high power general lighting.
