During a conference call yesterday on his company’s second-quarter earnings, Vonage Chairman and Interim CEO Jeffrey Citron disclosed that Vonage had “substantially completed” the deployment of technological work-arounds that would enable Vonage to offer service to customers without infringing upon patents held by Verizon Communications. Vonage, the largest stand-alone provider of voice-over-Internet protocol (VoIP) services in the U.S., has appealed a federal jury verdict, handed down last March, in which Vonage was found to have violated three VoIP-related patents held by Verizon. Although U.S. District Court Judge Claude Hilton awarded Verizon $58 million in damages and ordered Vonage to refrain from signing up new customers as long as it continued to use the infringing technology, the Federal Circuit appeals court later issued a stay of that injunction pending the outcome of Vonage’s appeal. According to Citron, Vonage began deploying work-arounds early last month that concern patents covering the connection of VoIP calls to landline phone networks and features such as voice mail and call waiting. Vonage, which has consulted with outside experts to ensure that the work-arounds do not infringe upon Verizon patents, has also finished work on a third work-around that would facilitate the transmission of VoIP calls on Wi-Fi networks. Noting that the “impact of the deployment is transparent to our customers,” Citron described the work-arounds as “a significant step toward moving ahead with our business in the wake of the Verizon litigation.”
