Seoul Semiconductor's technology is different from the patents that are now ineffective. In May 2008, NICHIA filed a lawsuit against the UK court for patent infringement. A related person from Seoul Semiconductor said that the decision will positively affect the corporate activities of Seoul Semiconductor and Seoul Semiconductor's dealer Avnet EMG.
In addition, Seoul Semiconductor has requested the US Trade Commission to ban the import of laser diode products from NICHIA. This request was received in mid-January and is now under investigation. It will be decided in early 2009. In addition, the core technology of all LED, UV, LD and other products used in NICHIA is infringing on the patented technology of Seoul Semiconductor, and is now appealing to the US and other courts for patent litigation.
Seoul Semiconductor is a company that respects intellectual property rights. In 2008, the company now has more than 1,600 patents and more than 300 patents belonging to LED source technology. 
Seoul Semiconductor Wins Patent Litigation with NICHIA
The patent for the LED component filed a “Patent Invalid Trial and Confirmation of Power Range Trial†with the Korean Patent Court. On July 25th, it stated that it was invalid and non-infringing on the grounds of “new regulatory deficiencies†and sentenced Seoul Semiconductor to victory. .
