Grv writes "A patent infringement suit that could have meant bad news for Voice over IP has failed. Ars reports that Judge David Folsom called Caritas' attempt to claim a patent on VOIP "aburd," leaving Comcast victorious in the suit. An appeal is planned, however. From the article, "The patent in question, no. 6,661,779, describes a "dial up telephone conferencing system controlled by an online computer network." At first glance, the patent doesn't look at all relevant to VoIP. However, Caritas said that the patent could be interpreted to cover any call that travels over the Internet via VoIP.""
