Seoul Semiconductor wins LED patent challenges
LED maker Seoul Semiconductor has won several patent disputes against rivals AOT and Itswell. The Patent Court of Korea has turned down appeals brought by Taiwan-based Advanced Optoelectronic Technology Inc. (AOT) and Korea-based Itswell in their patent disputes with Seoul Semiconductor.
The appeals were an attempt to overturn earlier decisions from the Korean Intellectual Property Tribunal. The Tribunal had rejected patent invalidation actions brought by AOT and Itswell against Seoul Semiconductors utility patent for producing white LEDs.
In 2005, Seoul Semiconductor filed and won all the preliminary injunctions for infringement of patent voting to its white LED against AOT and Itswell in Seoul Central District Court.
AOT and Itswell responded to these injunctions by filing invalidation actions against Seoul Semiconductors white LED patent in the Korean Intellectual Property Tribunal, claiming that the patent lacks novelty. The Tribunal rejected both AOT and Itswells invalidation actions at the end of last year.
AOT and Itswell subsequently appealed this Tribunal ruling by filing lawsuits with the Patent Court of Korea. These appeals have now been denied.
In addition, the Intellectual Property Office in Taiwan rejected AOTs invalidation action against Seoul Semiconductors white LED patent in Taiwan in August 3, 2007.
