The company Klausner Technologies is understood to be seeking US$360m in damages and future royalties from the companies.
It is alleging that iPhone infringed two patents it holds in relation to its ‘visual voicemail’ feature that allows voicemail users to selectively see who left voicemail messages and listen to them in any order.
AT&T is being sued for selling the iPhone with the visual voicemail function on board.
Klausner has already filed a number of suits against major technology companies over use of its patents.
It is suing Skype, Comcast and Cablevision for US$300m, alleging their voice over IP products infringe its patents.
In the past Vonage and America Online both settled with Klausner for an undisclosed sum in relation to the company’s patents.
Apple is also being sued in California as part of a class action suit claiming its exclusive deal with AT&T violates state laws. Apple is also being sued in relation to its anti-unblocking measures as well as the iPhone battery, which can’t be replaced by users.
