Apple, AT&T Sued Over iPhone Patents
Klausner Technologies says that it is suing Apple and AT&T for allegedly infringing on its Visual Voicemail patents. The company is seeking damages and future royalties estimated at $360 million.
The lawsuit asserts that Apple's iPhone Visual Voicemail infringes Klausner Technologies' U.S. Patents 5,572,576 and 5,283,818. These patents have already been licensed to various other companies that provide visual voicemail, including Time Warner's AOL for its AOL Voicemail services, Vonage Holdings for its Vonage Voicemail Plus services as well as others, under the Klausner Patents.
Klausner says that the iPhone violates it's intellectual property rights by allowing users to selectively retrieve voice messages via the iPhone's inbox display. Apple has called iPhone's Visual Voicemail "one of the greatest advances in the history of mankind ... without question."
The suit has been filed by the California law firm of Dovel & Luner in a federal court in the Eastern District of Texas. "We have litigated this patent successfully on two prior occasions," said Greg Dovel of Dovel & Luner, counsel for Klausner Technologies. "With the signing of each new licensee, we continue to receive further confirmation of the strength of our visual voicemail patents."
