Klausner Technologies Inc said on Monday the company had filed a $US360 million suit against Apple and AT&T over voicemail patents that Klausner claims the Apple iPhone infringes. New York-based Klausner said the lawsuit also names Comcast, Cablevision Systems and eBay's Skype as infringing its patent for "visual voicemail." The plaintiff seeks an additional $US300 million from the three. Klausner said in a statement that it filed the lawsuit in U.S. Court for the Eastern District of Texas. A copy of the filing was not yet available from the court.
