Court rules that Cox did not violate Verizon's phone patents

Cox Communications has won a court victory over Verizon as the U.S. Court of Appeals for the Federal Circuit ruled that the Atlanta-based cable MSO did not violate the RBOC's telephone network patents.

The Appeals court upheld an earlier U.S. District Court for the Eastern District of Virginia ruling that a number of Verizon's claims over six patents were invalid. Verizon filed a lawsuit in January 2008 arguing that Cox infringed on six packet technology patents. The court additionally found that Cox did not violate two other patents as Verizon alleged in its suit.

Although Verizon's Verizon Deputy General Counsel John Thorne said in an email statement that it would continue to promote its "innovations through patent licensing as well as monitor for unlawful infringement," the service hasn't announced whether it would appeal the ruling.
