Voice-over-Internet protocol (VoIP) market leader Vonage was dealt a serious blow last Friday, as a federal district court judge granted Verizon Communications’ request for a permanent injunction against Vonage’s unauthorized use of three VoIP patents held by Verizon. On March 8, a federal jury awarded Verizon $58 million in damages after Vonage was found to have infringed upon three Verizon patents that govern the connection of VoIP calls to the public switched telephone network, the connection of VoIP calls to WiFi networks, and customer features such as call waiting. Determining that the relief sought by Verizon is warranted because the imposition of fines and royalties alone “will not prevent continued erosion of the client base of the plaintiff,” U.S. District Court Judge Claude Hilton issued the injunction but postponed signing the order to consider Vonage’s request for a stay of the injunction pending appeal of the March 8 verdict. A hearing on Vonage’s motion is scheduled for April 6. Asserting that “we are confident that . . . customers will not experience service interruptions,” Vonage confirmed that it is developing a technical work-around that would enable it to continue service without relying on the technologies at the heart of the case. Nevertheless, the company—which has yet to post a profit—suffered drastic new losses on Wall Street, where share prices have plummeted by 26% since Friday. (Since its initial public offering last year, Vonage has seen its share price drop by 80%). Reacting to the court’s order, Vonage CEO Mike Snyder maintained that his company “has not infringed on any of Verizon’s patents” and declared: “our fight is far from over.”
