A U.S. District Court jury dealt a blow to Vonage Holdings, determining yesterday that the voice-over-Internet protocol (VoIP) pioneer had infringed three patents held by Verizon Communications related to VoIP technology and awarding Verizon $58 million in damages. The verdict constitutes a partial victory for Verizon, which had sought more than $197 million in damages plus royalties of 19%. After a day of deliberations, the eight-member jury concluded that Vonage had infringed two patents that cover the routing of VoIP calls over traditional phone networks as well as voicemail, call forwarding and other features. Vonage was also found to have infringed a third Verizon patent that pertains to the routing of Internet calls over Wi-Fi networks. Dismissing Vonage’s contention that the patents in question are invalid, the court ordered Vonage to forfeit $58 million and to pay Verizon a royalty of 5.5% on future Vonage sales. Upon receiving news of the verdict, attorneys for Verizon asked the court to impose a permanent injunction against future use of the patented technology by Vonage. A hearing on Verizon’s request is scheduled for March 23. While declaring Vonage guilty of infringing three patents, the jury also found that Vonage was not “willful” in its actions. Promising that its customers “should see no change to any aspect of their phone service,” Vonage vowed to appeal the verdict and fight Verizon’s motion for injunctive relief, asserting: “we don’t believe there is any basis to support Verizon’s request.”
