Vonage filed a declaratory-judgment action against Nortel seeking a declaration that U.S. Patent Nos. 6,091,808, 6,445,695, and 7,050,861 are invalid, void, and/or unenforceable. Nortel counterclaimed alleging Vonage induced infringement of the '808 patent. The parties settled and agreed to dismiss all claims and counterclaims without prejudice in 2008.
Related Texas action originally filed by Digital Packet Licensing, Inc. and later captioned Vonage Holdings Corp. v. SBC Internet Services, Inc., et al.
