Klausner Sues MetroPCS Over Voicemail Patents
Jan 27, 2012, 1:27 PM by Eric M. Zeman
Klausner Technologies today filed a lawsuit against MetroPCS, claiming that the pre-paid carrier is violating some of its 25 visual voicemail patents with its devices and services. Klausner licenses its visual voicemail patents to some 37 hardware makers and network operators around the world. Klausner didn't say if it is seeking damages, an injunction, or if it is demanding a licensing agreement. Klausner has filed similar suits against other smartphone makers and network operators. The suit was filed in federal court in the Eastern District of Texas.
