AT&T filed a lawsuit against VoIP provider Vonage Holdings, seeking damages for alleged patent infringement.
AT&T Inc. on Friday filed a lawsuit against VOIP provider Vonage Holdings Corp., seeking damages for alleged patent infringement.
The lawsuit comes just days after Vonage settled a patent-infringement lawsuit with telecom provider Sprint Nextel Corp.
In a filing with the U.S. District Court for the Western District of Wisconsin, AT&T alleged that Vonage wilfully infringed an AT&T patent related to telephone systems that allow people to make VOIP (voice-over-Internet Protocol) calls using standard telephone devices.
