LG announced this morning that they've filed a lawsuit against Quanta Computer. According to their press release, Quanta has infringed on four patents related to DVD standard.
LG Electronics (LG), a global leader and technology innovator in consumer electronics, filed a lawsuit against Taiwanese computer maker Quanta Computers (Quanta), for infringement of patents related to LG’s DVD technology. LG is seeking an injunction for Quanta’s use of this technology as well as monetary compensation in the suit that was filed in U.S. District Court, the Western District of Wisconsin on July 3, 2007.

LG’s claims include infringement of four patents related to DVD standard. Quanta has been using these patents without LG’s permission to produce notebook computers that were supplied to U.S. computer companies.
Sadly, this isn't the first time LG has sued Quanta over a patent. The company filed a suit against Quanta in 2000 and it has been tied up in the courts ever since. If you'd like to read more, LG's entire press release can be found here.
