Philips files patent lawsuit against Seoul Semiconductor


Philips has claimed that many of Seoul Semiconductor (SSC)’s LED products infringe several Philips patents, and that a patent owned by SSC should be ruled invalid. An LED patent lawsuit has been filed by Philips and its LED subsidiary Philips Lumileds against Korea based LED maker Seoul Semiconductor Company Ltd. The lawsuit, filed on March 4, 2011 in the US district court, claims infringement of five patents owned by Lumileds. Also, Philips is seeking a declaratory judgment that a patent assigned to SSC is invalid.
