LED maker Seoul Semiconductor has won a lawsuit filed in the Korean Supreme Court on 14 March by Advanced Optoelectronic Technology Inc (AOT) of Hsinchu, Taiwan seeking to have Seoul Semiconductor’s white LED patent ruled invalid.

Last October, the Patent Court of Korea turned down appeals by both AOT and LED maker Itswell of Cheongwon Chungbuk, Korea to overturn the Korean Intellectual Property Tribunal’s rejection of invalidation actions regarding Seoul Semiconductor’s patent.

Subsequently, in late October, the Seoul High Court ruled in favor of a Seoul Semiconductor latent infringement lawsuit that Itswell should pay $1.2m in damages, as well as an injunction against any further infringing activities.

Seoul Semiconductor has now also signed a patent license agreement with Itswell after the firms reached an amicable settlement of the various lawsuits and claims relating to white LED patents.

Seoul Semiconductor says that the license agreement will allow it to collect royalty payments from Itswell for the use of its patent on white LED manufacturing technology in the past and for future use of the patent.

“With the Itswell license agreement, we will help create an atmosphere where companies respect each others’ patents, and at the same time build a cooperative relationship with other LED corporations,” says Seoul Semiconductor. “However, we will take strong action against those who do not respect intellectual property rights.”
