The case follows a spate patent litigation between companies involved in the growing market in VoIP technology.
Earlier this week Vonage acquired three VoIP patents from Digital Packet Licensing in a deal aimed at putting the company in control of outstanding patent lawsuits filed by Sprint Communications, Verizon Communications and others.
Vonage has also acquired Digital Packet’s key licensing agreements with Motorola, Time Warner and Qwest Communications.
Klausner Technologies, founded by PDA and electronic organiser pioneer Judah Klausner, controls over 25 patents worldwide covering VoIP voicemail services where subscribers can view and select voice messages through their PC or mobile phone inboxes.
The firm recently granted a license to AOL for its Voicemail and VoIP voicemail services under the patent at the centre of its dispute with Vonage.
Judah Klausner said, “We approached Vonage in January and offered them the opportunity to enter into a licensing agreement that could have allowed them to continue providing their VoIP voicemail, a key feature of their internet phone service.”
The company was “unable to wait any longer” for a response from Vonage, he added.
