(InfoWorld) - 3M Co. has filed suit against several big electronics companies, including Sony and Lenovo Group, for allegedly violating two patents related to lithium-ion battery technology. In a suit filed Wednesday in the U.S. District Court of Minnesota, 3M charged Sony, Lenovo, Matsushita Industrial Electric Co., Panasonic Corp. of North America, Hitachi, CDW, and others of violating patents related to the composition of the cathode, or positive electrode, used in lithium-ion batteries they manufactured, imported, or sold in the United States. 3M is seeking financial damages and injunction from the court to stop the companies from infringing its battery patents. "3M has suffered, and will continue to suffer, irreparable injury and damages," the company said in the complaint, asking that it be awarded treble damages for the harm allegedly caused by the defendants. A Sony spokesman in Tokyo declined to comment, saying the company is still gathering information related to the suit. Matsushita also declined to comment, saying it had not yet received a copy of 3M's complaint. Attempts to contact representatives at other companies named as defendants in the lawsuit were not immediately successful.

(InfoWorld) - LG ElectronicsÂ has filed a lawsuit against the world's largest contract manufacturer of laptop PCs over the infringement of four patents related to DVD (digital video disc) technology, the company said Wednesday. The South Korean electronics maker is seeking an injunction against Taiwan's Quanta Computer to put a stop to its use of the technology, as well as cash compensation. The suit was filed in U.S. District Court, Western District of Wisconsin on July 3, LG said. LG alleged that Quanta has been using the infringing technology to produce laptop PCs that have been supplied to U.S. computer vendors. Quanta counts Hewlett-Packard, Dell, and a number of other PC vendors among its customers. The two companies have another outstanding lawsuit in the U.S. on which LG expects a decision in the first half of 2008. LG sued Quanta in the U.S. District Court of Northern California in 2000 over the alleged infringement of PC-related patents. Originally, the trial court decided in favor of Quanta, but the U.S. Court of Appeals overturned the verdict. LG said it expects the ruling in this case to be in its favor. Quanta declined to immediately comment on the lawsuit. LG holds 5,000 international patents on DVD technologies, it said.
