Verizon loses out in VoIP patent case, signs accord with Comcast

7 Oct 2008

A jury in the US has ruled that cable operator Cox Communications did not infringe on six patents owned by Verizon Communications relating to IP telephony services. The jury decision from the US District Court in Virginia found against Verizon on all six of its complaints against Cox. Verizon started the suit earlier this year, claiming that Cox had violated patents connected to its enhanced internet domain name server and other systems. Verizon had been seeking damages of more than USD400 million. Verizon had previously settled a similar case against VoIP provider Vonage under which Vonage agreed to pay USD117.5 million.

Separately, Verizon has reached an accord with another cable operator, Comcast Corp, under which the two companies have agreed not to sue one another over patent infringements for a five-year period. Comcast has also signed a contract with Verizon Communications’ 55%-owned cellular subsidiary Verizon Wireless, under which Comcast employees will use Verizon Wireless for mobile services for five years, the Wall Street Journal reports.
