The U.S. Court of Appeals for the Federal Circuit has refused to grant Vonage a retrial of the patent case it lost against Verizon Communications earlier this year.

Vonage had asked that its case be send back to a lower court for a new trial in the wake of a Supreme Court ruling earlier this week that would make it easier to challenge dubious patents, awarded to advances that are part of the normal court of advancing technology and involve no real innovation.

Vonage, which was found to have violated three Verizon patents with its VoIP service, has maintained from the outset that the jury’s interpretation of the Verizon patents was too broad. Some VoIP experts have agreed that, based on the Verizon-Vonage case, virtually any VoIP service could be found in violation of the Verizon patents.

Vonage continues to offer its service under a permanent stay granted to the company while it appeals the original jury decision.
