On July 15, Samsung LED Co., Ltd. filed a complaint with the United States International Trade Commission (ITC) in which it has requested the ITC to issue an exclusion order barring importation of products of OSRAM, OSRAM Opto Semiconductors, and OSRAM Sylvania Inc. into the United States.

Samsung LED also filed suit for patent infringement in the United States District Court for the District of Delaware to seek damages and a permanent injunction barring OSRAM's infringement.

Samsung LED alleges infringement of eight patents on core LED technologies. The patented technology is used in a wide range of products, including lighting, automobiles, projectors, cell phone screens, and televisions. OSRAM's TOPLED, DRAGON, OSLON, CERAMOS, and OSLUX devices, and the products in which they are used, are targets of Samsung LED's complaints.

Osram said on June 6 it was suing the Samsung and LG group of companies for alleged infringement of patents on light emitting diodes (LED) technology.

In June, Samsung LED also filed a patent infringement action against OSRAM in a Korean court.

"Samsung LED is very proud of its innovative LED technology for which it has been awarded many patents around the world. Samsung LED is a market leader in LEDs and is proud to see its LEDs used in many of the leading consumer electronic products worldwide. Samsung LED intends to vigorously enforce its intellectual property rights, and these lawsuits reflect Samsung LED?s commitment to that enforcement," Samsung LED representatives said.

Samsung LED's core technology is related to LED lighting, including LEDs for televisions. The company has applied for and registered about 4,000 patents, including 2,000 patents in Korea and 700 patents in the United States.
