Seoul Semiconductor wins US patent infringement lawsuit against Craig Electronics

After South Korean LED maker Seoul Semiconductor filed a lawsuit in July 2014 asserting that US-based Craig Electronics' sales of LED back-lighting unit (BLU) products infringed five of its patents, the US Federal District Court has now issued a judgment stating that Craig has acknowledged infringement of all the asserted patents as well as the validity of the patents.

The patents cover a wide range of technologies including, but not limited to, back-lighting units (BLUs), LED packaging, LED chips and epitaxial layers, and black hole lenses. Together, the patented technologies cover essential components and features of modern back-lighting units, including manufacturing systems, LED displays, and optical devices. In particular, Seoul Semiconductor's patented technology for lenses - having a curved shape at the center – helps to ensure uniform illumination across the entire area of the liquid-crystal display for back-lighting units, enhancing image quality on the LCD display, the firm claims.

"To safeguard our licensees' and customers' interests in using Seoul Semiconductor's patented technology, Seoul Semiconductor will continue to discover infringing LED application products in the market and maintains an enforcement program that will consider any and all enforcement options against third-party infringers who do not respect Seoul Semiconductor's intellectual property rights," states the firm. "Indeed, we are pursuing another patent infringement lawsuit against suspected infringers."
