The Court of Appeals for the Federal Circuit, which hears appeals on patent cases, has agreed to stay a district court's injunction against Vonage. This means that Vonage can continue signing up new customers, even though the lower court found that Vonage was infringing Verizon's patents on voice-over-IP technology.
This ruling doesn't deal with the larger, more important question of whether or not Vonage was in fact infringing–that question is still being appealed, and the Federal Circuit expects to hear arguments on that on June 25. Briefs from Verizon and Vonage are expected May 30.
Until the Federal Circuit makes a decision on the underlying infringement suit, Vonage will pay a percentage of its profits into an account that will be turned over to the winner of the case.
