Klausner Files More Visual Voicemail Patent Lawsuits

Klausner Technologies has filed suit against NEC, Siemens Enterprise Communications, Primus Telecommunications, Samsung, PAETEC, Alcatel-Lucent, J2 Global Communications, Mitel, Toshiba, Shoretel, and Windstream for patent infringement under the Klausner U.S. Visual Voicemail patents.

Klausner Technologies currently has 33 Visual Voicemail patent licensees under its U.S., European, and Asian patents, including major U.S. and European mobile operators, international cell phone manufacturers, cable/VOIP providers as well as providers of Visual Voicemail products and services for the enterprise market. Avaya Inc. has recently signed a patent license under the Klausner Technologies’ Visual Voicemail patents for its own enterprise voicemail products.

“33 companies worldwide have now signed patent license agreements with us under our Visual Voicemail patents. As the inventor of these patents and on behalf of our company, I just can’t allow unlicensed companies to use our IP,” said Judah Klausner, Klausner Technologies’ president. The suit has been filed in federal court in the Eastern District of Texas by the California law firm of Dovel & Luner.

Klausner Technologies owns a catalogue of 25 Visual Voicemail patents, in the U.S., Canada, Europe, Taiwan, Korea, and Japan covering the basic Visual Voicemail feature in which users can selectively view and listen to their voice messages via their mobile phones or computers.
