SEOUL, KOREA--(Marketwire - November 12, 2007) - In the news release, "Seoul Semiconductor Has Substantially Prevailed at U.S. Design Case," issued Friday, November 09, 2007, by Seoul Semiconductor, we are advised by the company that the first sentence of the second paragraph should read "The only product at issue was Seoul's side view LED 902 for mobile phone BLUs sold in the United States and the product was already supposed to be discontinued" rather than "The only product at issue was Seoul's side view LED 902 sold in the United States" as originally issued.

Seoul Semiconductor Has Substantially Prevailed at U.S. Design Case

SEOUL, KOREA -- November 09, 2007 -- Seoul Semiconductor (KOSDAQ: 046890), one of the eight largest LED manufacturers in the world, found not liable for damages on three of four Nichia Corporation's U.S. Design Patents; Jury award limited to $62 recovery on 4th patent at Northern California District Court design patent case.

The only product at issue was Seoul's side view LED 902 for mobile phone BLUs sold in the United States and the product was already supposed to be discontinued. Seoul Semiconductor vindicated that, after almost two years of litigation, the sales of its side view LED 902 are actually non-infringing and that it has substantially prevailed in this litigation.

Seoul Semiconductor continues to believe that Nichia's U.S. design patents are invalid, and has asked the U.S. Patent and Trademark Office to reexamine all four patents asserted against it. Nichia's same design patents were previously invalidated by the Korean Intellectual Property Office in December 2006.

Seoul Semiconductor relies for its success on the strength of its own intellectual property and its revolutionary advances in technology. Seoul Semiconductor has fulfilled customer's best satisfaction through its consistent advanced technologies and will be the company, which provides a better value to the world.
