KOREAN ELECTRONICS GIANT Samsung has lodged a patent infringement complaint against Siemens' light emitting diode (LED) division with the US International Trade Commission (ITC).
Samsung wants the ITC to ban imports of LED products from Osram, Siemens' LED light bulb company, and its affiliates Osram Opto Semiconductor and Osram Sylvania, claiming that Siemens infringed eight of its patents relating to LED technology.
Samsung is also suing the company in the US District Court for Delaware, where it wants a permanent injunction against Osram and damages for alleged past infringement. It's not clear how much of a payment it is looking for and whether it will accept a licensing deal with Osram if the latter is found to have infringed those patents.
The low-power LED technology is used in a variety of products, including cars, projectors, phones and TVs. Samsung alleges that several Osram products infringe its patents, including the TopLED, Dragon, Oslon, Ceramos and Oslux ranges.
Reuters reports that Osram believes it is in a "good position" to fight off Samsung's patent claims. Samsung, on the other hand, said it will "vigorously enforce" its intellectual property rights and threatened to sue others that infringe its patents or work with Osram to import infringing products into the US.
The Korean electronics giant has an extensive patent collection numbering upwards of 4,000 patents. Half of these are filed in South Korea, while around 700 are filed in the US.
Samsung is also involved in a heated battle with Apple over smartphone patents relating to the Iphone and Galaxy ranges, one of the largest patent cases Samsung has engaged in, the results of which will be vital to its phone business.
This latest move by Samsung follows a lawsuit launched by Osram in early June against both Samsung and LG for patent infringement relating to the same LED technology. In the same month Samsung sued the Korean division of Osram over patent infringement, while LG also counter-sued, making this legal war over LED technology a bitter tangle of tit-for-tat lawsuits. µ
