Suwon, South Korea--Last week, Osram (Regensburg, Germany) filed lawsuits against Samsung and LG, alleging infringement on Osram's white-emitting and surface-mountable LEDs; now, Samsung LED has filed a patent-infringement lawsuit against Osram Korea, alleging infringement on eight of Samsung's patents. The defendants include Osram Korea and two companies that sell Osram's products in Korea: Barun Electronics and Dabo Industrial System.

The eight patents in the suit relate to LED chip and package technology used in LED lenses and high-power applications.

"We are developing evidence to show that Samsung LED is not infringing any valid claim of Osram's patents, as well as evidence of Osram's unauthorized use of our patents; we are evaluating every contingency and will vigorously defend our technology," said Jun Sung Park, vice president and the head of the IP and legal affairs team at Samsung LED.
