Google, Verizon, others sued over voicemail patent
Published: 27 Aug 2008 09:05 BST
A patent-holding company that has won settlements from Apple, AT&T and others sued Google, Verizon and a handful of other companies on Tuesday for allegedly infringing on patents related to voicemail, according to a report from Reuters.
In addition to Google and Verizon, other defendants in the lawsuit filed by Klausner Technologies are: Cox Communications, LG Electronics, Comverse Technology, Embarq, PhoneFusion, RingCentral and Grand Central, which was acquired by Google last year.
The lawsuit, filed in US District Court in Tyler, Texas, alleges the companies are infringing patents related to visual voicemail.
Representatives from Google, Cox and PhoneFusion said they had not seen the lawsuit and declined to comment. An Embarq spokesman provided this emailed statement: "Embarq has not been served with any such lawsuit, but is confident that any claims that it has infringed on someone else's patent would be unfounded."
A Verizon spokeswoman provided this statement via email: "We anticipated Klausner's action. We filed a declaratory judgment action in New York federal court on 13 August. We are seeking a declaration that Klausner's visual voicemail patent is invalid and that Verizon's system does not infringe the patent in any event."

The other defendants were either working on getting comment or did not immediately return calls and emails seeking comment.
Klausner Technologies, a private company that holds several VoIP patents, settled a lawsuit in June with Apple, which offers visual voicemail in its iPhone.
Klausner also settled with AT&T, eBay, which owns Skype, and Comcast, which agreed to a licensing deal as part of its settlement. The company remains in talks with Cablevision Systems, while Sprint Nextel signed a licensing deal and was not sued, Reuters reported.
Previously, Klausner sued and settled with AOL in 2006, and with Vonage last year. Terms of the settlements were not disclosed.
Klausner's lawsuit in December alleged that the defendants infringed on technology that visually alerts people when they get a new voice message and lets them selectively retrieve the messages.
