Samsung LED Co. Ltd. said it had filed a complaint with the U.S. fair trade commission to ban imports of LED products from Siemens' (SIEGn.DE) light bulb unit Osram and affiliates Osram Opto Semiconductors and Osram Sylvania Inc.

Samsung LED said in a statement on Sunday it had also filed a lawsuit for patent infringement with the U.S. District Court for Delaware to seek damages and a permanent injunction barring Osram's infringement.

The complaint and the lawsuit were filed separately on Friday with the U.S. International Trade Commission (ITC) and the Delaware court, according to the statement.

Samsung LED alleged Osram infringed eight patents on core LED technologies. The patented technologies are used in a range of products, including lighting, automobiles, projectors, mobile phone screens and TVs.

A spokesman for Osram told Reuters on Sunday the company believed it was in a good position and well prepared for any complaints filed by Samsung.

Osram said on June 6 it was suing the Samsung <005930.KS> and LG <066570.KS> group of companies for alleged infringement of patents on light emitting diodes (LED) technology.

The complaints filed by the Korean LED maker, affiliated with Samsung Electronics, target Osram's TopLED, Dragon, Oslon, Ceramos and Oslux devices and the products in which they are used.

Samsung warned in the statement it would continue to take additional legal action against those who may import, use or deal with the named Osram LEDs in the U.S. market.

Samsung LED intends to vigorously enforce its intellectual property rights, and these lawsuits reflect Samsung LED's commitment to that enforcement, the statement said.

Samsung LED said it had applied for and registered about 4,000 patents, including 2,000 in Korea and 700 in the U.S.

In June, Samsung LED filed a patent infringement lawsuit against Osram Korea and two Korean sales agents of the German company at a Seoul district court.

Another South Korean electronics giant, LG Electronics Inc., joined Samsung LED this month to countersue Osram, after the German firm filed lawsuits against the Korean rivals in the U.S., Germany and Japan, and another against LG in China.
