Verizon Communications has lost its VoIP patent infringement case against Cox Communications Inc, the Wall Street Journal reports. Verizon filed papers in Eastern District Court of Virginia on Jan. 11, 2008 alleging that Cox violated eight patents related to the technology used for completing IP voice calls. The lawsuit came after Verizon had successfully argued that Vonage was infringing its patents.
Verizon included in the lawsuit claims of infringement of four patents Vonage was found to have violated in an earlier case. Verizon was awarded $120 million in damages in that case. But the jury in the Eastern District of Virginia ruled that Cox Communications did not infringe on six Verizon patents.
In addtion to Cox Communications, other leading cable operators perhaps most relieved of all, as it might be hard to defend the notion that any of the leading cable providers were innocent, had Cox been found to be infringing. But other indpendent VoIP providers also have to be breathing a little easier as well.
Had Cox been found to be infringing, it isn't so clear how any other cable company might have escaped litigation, cable or independent VoIP providers alike.
Verizon apparently has recently reached a deal with Comcast in which both companies agreed not to sue each other over patent issues for five years. A Verizon lawsuit against Charter Communications for VoIP patent infringement is still pending.
