Another day, another lawsuit. Klausner Technologies has filed a patent lawsuit under its visual voicemail patents against Apple and AT&T on the iPhone, with damages and future royalties estimated at US$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 patent, according to the folks at Klausner Technologies. The company also claims that Apple’s Newton, was, in fact, covered under an OEM (original equipment manufacturer) patent license granted by Klausner Technologies founder Judah Klausner over 20 years ago under his landmark US Patent 4,117,542.
The company says the iPhone violates Klausner’s intellectual property rights by allowing users to selectively retrieve voice messages via the iPhone’s inbox display. The suit has been filed by the California law firm of Dovel & Luner in a federal court in the Eastern District of Texas.
