Motorola, RIM Sued for Using Visual Voice Mail without License

Lora Bentley

The Washington Post reported Monday that Klausner Technologies has filed patent infringement suits against Motorola and Research In Motion in a Texas federal court. The patent holding company claims both phone makers are using its patented "visual voice mail" on certain smartphones without first having licensed the patent.


Motorola's Cliq phone and certain RIM Blackberry Bold 9700 phones are the ones that use visual voice mail illegally, according to Klausner. Visual voice mail allows users to see a list of voice mail messages so as to decide which one to retrieve first.


Klausner has been no stranger to intellectual property litigation. In years past, the company has also sued Apple, AT&T, Cisco Systems and Avaya over the same patent.
