Shulin District, New Taipei City, Taiwan, July 13, 2020- Everlight Electronics(“Everlight”) and Epileds Technologies(“Epileds”) have always committed to technological innovation and created the patent litigation strategy alliance. On March 14, 2018, we filed a nullity action against Seoul Semiconductor(“SSC”) in the German Federal Patent Court(“the Court”) seeking a judgment that all claims of SSC’s Europe patent EP1697983(German patent DE60341314.5) should be invalid. The patent-in-suit is related to the surface roughness technology of vertical chip. On July 2, 2020, the Court has rendered the judgment, and has decided that the all claims of SSC’s Europe patent EP1697983(German patent DE60341314.5) are invalid.  According to the judgement of the Court, SSC has been ordered to bear the costs for the proceedings.  Everlight and Epileds affirmed the result of this judgment and won the victory by defending our customers' benefits and rights.
