Sprint Nextel Sues Vonage, Others over VoIP

Sprint Nextel Corp. on Tuesday said it has sued Vonage Holdings Corp., Voiceglo Holdings Inc. and Theglobe.com Inc., accusing them of infringing on seven patents related to Internet telephony technology.

The patent-infringement lawsuit, filed in federal court in Kansas by one of Sprint Nextel's subsidiaries, seeks an injunction that would bar the defendants from using the communication company's patented technology. The suit also seeks unspecified monetary damages.

The patents cover technology that enable the processing and delivery of voice and data packets used in Internet telephony, or voice over Internet protocol.
