Korean electronics company LG has issued a complaint to the US International Trade Commission requesting that the importation and marketing of Sony's PlayStation 3 to the United States be banned due to an alleged infringement of four separate patents relating to the playback of Blu-Ray discs.
The documents relating to the complaint, which were passed on to GamesIndustry.biz by the Foss Patents blog, refer to the PS3 specifically, but also make clear that the alleged infringements could also related to other devices carrying Blu-Ray players - referring to "certain electronic devices having a Blu-Ray Disc player and components thereof".
Bloomberg has reported that LG has also filed a separate patent infringement complaint against Sony with regard to Bravia televsions.
Last December, Sony filed a patent infringement complaint against LG concerning "computer-implemented inventions", requesting that the ITC ban the import and distribution of several of its mobile phones to the US. This latest complaint from LG may be part of that ongoing legal tussle.
