Telecom veteran questions Verizon VOIP patents
18 April 2007
Two patents owned by Verizon Communications in its
infringement lawsuit against Vonage Holdings are invalid, and if
allowed to stand, could threaten all competing VOIP (voice over
Internet Protocol) services, a telecommunications industry veteran said
Tuesday.
Two of the three Verizon patents a jury upheld in a March decision were described in a standards group called the VOIP Forum before Verizon filed for the patents, said Daniel Berninger, who had a hand in launching Vonage but now works as a telecom analyst for Tier1Research.com. The VOIP Forum described the name translation call-processing step in an open standard developed in 1996, and Verizon applied for the two patents in March 1997 and February 2000, he said in an interview about the case.
