Klausner Technologies, a patent licensing firm that has targeted numerous companies in the wireless industry, filed a lawsuit against Motorola and Research In Motion for violating its visual voicemail patents.
In the past, Klausner has filed suits against Apple, LG Electronics, Cox Communications, Verizon and others. Apple, AT&T, Sprint Nextel and Verizon are among 24 companies that currently license visual voicemail technology from Klausner.
The latest suits were filed in federal court in the Eastern District of Texas. The lawsuits claim that Motorola's first Android-powered phone, the Cliq, and RIM's new BlackBerry Bold 9700 violate Klausner's patents.
Visual voicemail lets users see their messages and decide which ones to respond to. Klausner grabbed the attention of the wireless world back in late 2007, when the company filed suit against Apple and six other companies for $360 million.
Representatives from Motorola and RIM declined to comment on the lawsuit.
