Seoul Semiconductor Announces Its Position on US 5,075,742 Patent

Seoul Semiconductor Co., Ltd. (“Seoul”) announced that the companies manufacturing or packaging blue, green, white or UV light emitting devices made from the semiconductor indium gallium nitride may be subject to patents owned by Seoul. These patents include U.S. Patent No. 5,075,742, which was the subject of a recent ruling issued by the United States District Court for the Eastern District of Texas. The ruling supports Seoul's view that the patent is fundamental to indium gallium nitride-based light emitting device technology.

This Patent, including its family of patents in Japan, Germany, UK, and France, are available for licensing from Seoul to appropriate business partners. Under the laws of various countries in which Seoul's patents are held, infringement of Seoul's patents may subject a company to injunctive relief, as well as monetary damages for past infringement. Already, three (3) companies have received a license to use Seoul’s patents.
   
Seoul respects intellectual property rights of others and will continue to compete with those companies also respecting intellectual property rights. Seoul will also take necessary steps to protect its intellectual property rights against those who fail to respect its intellectual property rights.
