Vonage faces more patent claims
Published: 11 Jul 2006 09:55 BST
Vonage is once again in the legal hot seat, having been sued by yet another company for allegedly infringing on patents.
Patent-holding company Klausner Technologies said on Monday that it had filed suit against Vonage in federal court in the eastern district of Texas. Klausner claims that Vonage, which sells an Internet voice-calling service, is infringing on patents being used as part of its voicemail service. Klausner is seeking damages and royalties worth about $180m.
Vonage is already being sued by two large phone companies for supposedly infringing on patents. Last year, a subsidiary of Sprint-Nextel filed suit against Vonage. Then, in June, Verizon Communications filed suit against the company, claiming it had infringed on seven patents that describe technology for completing phone calls between Voice over IP (VoIP) users and people using phones on the traditional public switched network.
Separately, Vonage said on Monday that it has bought three patents from Digital Packet Licensing for an undisclosed amount. Vonage said the patents will help it in its fight against the Sprint and Verizon litigation. Companies such as Motorola, Time Warner and Qwest Communications are already licensing technology from Digital Packet on these VoIP patents. As a result of acquiring the VoIP patents, Vonage also assumes ownership and control over these agreements.
"We're committed to developing, acquiring and protecting the root technologies that are at the heart of our business," Michael Tribolet, president of Vonage America, said in a statement. "The acquisition of these patents is part of Vonage's strategic plan to further develop our core technology and build on our innovative, affordable and feature-rich phone service. Vonage's strategic plan also includes a concerted effort to grow, create and acquire other significant intellectual property portfolios."
The latest lawsuit has come as Vonage tries to recover from a disappointing stock-market debut. The company lost nearly 30 percent of its value in the first week of trading. The Internet telephony provider has also been gearing up to defend itself against several investor lawsuits. Shareholders allege that the company misled them and created artificial demand for the stock.
Klausner, a privately held company that controls several patents for VoIP technology, settled a lawsuit earlier this year with Time Warner for using its technology in AOL voice mail. Under the settlement, Klausner granted a licence to AOL to use the patent. Financial terms were not disclosed.
