Verizon sues Charter for VoIP patent infringement

Last week, Verizon Communications drew a legal bead on Charter Communications by claiming that Charter has infringed on eight patents that relate to the provisioning of VoIP calls.

Verizon, which filed its complaint in the U.S. District Court for the Eastern District of Texas, is asking for a court order that would block Charter from using the VoIP-related technology. Verizon is also seeking unspecified cash compensation from Charter for using the technologies without its permission.

“Charter is presently analyzing Verizon’s claims and our defenses,” Charter said in a statement. “We cannot comment on them at this time, however, we intend to vigorously defend ourselves in this suit."

Last month, Verizon also filed suit against Cox Communications over the same eight patents (story here). 

Last year, four of the eight patents became the focal point of Verizon’s successful lawsuit against standalone VoIP provider Vonage. Vonage settled that case for $120 million after a jury in Virginia found that Vonage infringed on three of the patents.

Since cable operators rely on the PacketCable architecture to deliver VoIP calls, other cable operators could also be subject to lawsuits from Verizon.

Verizon has seen its landlines service dwindle in the past few years, partially due to customers opting for VoIP services from cable operators.
