Apple, Comcast sued over patent for visual voice mail

Apple, Comcast and AT&T were sued by a New York company for use of technology that provides visual text for voice mail. Closely held Klausner Technologies said it filed the complaint Monday in federal court in Texas. Cablevision Systems and eBay's Skype unit were also named as defendants. Klausner said it's seeking $360 million from AT&T and Apple for royalties on Apple's iPhone, and $300 million from Comcast, Cablevision and Skype. Klausner, whose only business is licensing patents, has sued other companies over the technology, including Vonage Holdings, which settled the case.
