ATT Accuses Vonage of Violating VoIP Patents


America’s leading telephone operator, ATT Inc., filed an intellectual property lawsuit against the troubled VoIP provider, Vonage Holdings Corp yesterday, seeking damages for alleged patent infringement.

AT&T’s lawsuit, filed at a U.S. District Court in Wisconsin, alleges that Vonage willfully violated an ATT patent concerning telephone systems that allow customers to make VoIP calls using standard telephone equipment.

AT&T claims that it tried to reach a licensing agreement with Vonage, but was unsuccessful, forcing it to file suit against its smaller competitor.

This latest legal woe comes just days after Vonage settled a similar dispute with wireless carrier, Sprint Nextel, for $80 million. Vonage is also fighting a losing battle against New York-based telephone giant, Verizon Communications, to which it lost another massive patent infringement suit earlier this year.
