Patent holder previously attacked Apple, AT&T
Klausner Technologies has expanded its patent litigation efforts with new lawsuits aimed at Motorola and RIM, according to the Associated Press. The company claims both handset makers have violated its patents relating to visual voicemail technology. Although Motorola is said to license the technology for many of its phones, Klausner claims the Cliq handset utilizes the patented system without permission.
The patent holding company first sued Apple and AT&T in 2007 over the same technology. The terms of the subsequent licensing deal were never publicly disclosed, however the court filing indicated Klausner was initially seeking $360 million in damages.
Other targets of Klausner's legal team have included Comcast, Cablevision, Time Warner, Vonage, Google, and LG, among others. The patent holder claims to have won several suits, while most of the defendants have reached a settlement rather than fighting the battle in court.
