Vonage Holdings Corp., a leading provider of broadband telephone services, announced that it has acquired ownership of three patents from Digital Packet Licensing Inc. that enable voice over internet protocol technology (VoIP). The three acquired patents, U.S. Patent Nos. 4,782,485, 5,018,136 and 5,444,707, are directed to the compression of packetized digital signals commonly used in VoIP technology.

"We're committed to developing, acquiring and protecting the root technologies that are at the heart of our business," said Michael Tribolet, president, Vonage America Inc. "The acquisition of these patents is part of Vonage's strategic plan to further develop our core technology and build on our innovative, affordable and feature-rich phone service. Vonage's strategic plan also includes a concerted effort to grow, create and acquire other significant intellectual property portfolios."

Vonage's acquisition of these three significant patents now places Vonage in control of pending litigation against Sprint Communications LP and Verizon Communications, among others, in federal court for infringement of one of these VoIP patents. Vonage is presently in cross-licensing negotiations with regard to them. Leading telecommunications companies including Motorola, Time Warner, Qwest Communications and others have already settled with and/or taken a license from Digital Packet on these VoIP patents, and as a result of acquiring the VoIP patents, Vonage also assumes ownership and control over these agreements.
