Klausner Sues VZW and Goog
Klausner Technologies today grew the scope of its licensing claims by suing multiple other companies it believes are treading on its patents for a visual voicemail system. The company claims that software developed by Google, LG, Verizon and six other firms are violating patents from 1992 onwards for a system that permits listening to voicemail out of order through a graphical interface.
