Verizon Sues Charter Communications for Infringing VoIP Patents


12/02/2008

New York-based telecom giant, Verizon Communications, has launched a patent infringement lawsuit against Charter Communications, its second legal action against a major cable company in the space of a month.

Verizon filed its case against Charter on February 5 in the U.S. District Court for the Eastern District of Texas, which has traditionally been favourable to plaintiffs in patent infringement cases.

The telecom giant is alleging that Charter’s digital phone service infringes on eight Verizon-owned patents relating to the delivery of phone services over data networks. An almost identical lawsuit, citing the same eight patents, was filed against another American cable company, Cox Communications, last month.

In the Charter case, Verizon is seeking damages that are no less than a reasonable royalty, as well as an injunction blocking Charter from using the technology. It says that the Texas court has jurisdiction over this matter because Charter provides service to some 182,200 customers in the state.

The cable company would only say that it is currently analyzing Verizon’s claims and cannot comment on our defenses at this time, but Charter does intend to vigorously defend itself.

Verizon won a $120 million patent infringement settlement against independent VoIP provider, Vonage, last October, in a case involving two of the same patents being used against Charter and Cox.
