A federal appeals judge suggested Monday the possibility of a compromise in the patent dispute between Internet phone carrier Vonage Holdings Corp. and Verizon Communications Inc. that would allow Vonage to continue signing up new customers while it modifies its technologies.

Judge Timothy B. Dyk, part of the three-judge panel of the U.S. Court of Appeals for the Federal Circuit considering the case, made the remark during oral arguments. The panel is considering Holmdel, N.J.-based Vonage’s appeal of a March jury verdict that found the company infringed on three Verizon patents in constructing its Internet phone system.
