On November 23, 2009, Klausner Technologies Inc., which holds 25 patents for visual voicemail technology, commenced actions against Motorola Inc. and Research In Motion, in the U.S. District Court for the Eastern District of Texas, alleging that the cell phone manufacturers’ new models infringe its patents. Klausner has sued various mobile operators and manufacturers in the past, and apparently has negotiated patent licenses with many of them. The latest foray into Texas court is interesting in that prior models of Motorola and Blackberry devices with visual voicemail are licensed under the patents, but not the latest ones.
