The U.S. Court of Appeals for the Federal Circuit has affirmed a $139.8 million jury verdict in favor of Sprint Communications against Time Warner for infringement of five Sprint patents related to VoIP technology. The appeals court concluded that the district properly admitted evidence relating to the jury verdict in an earlier, related case brought by Sprint against Vonage, another carrier offering VoIP service. Time Warner failed to show that the evidence presented at trial was insufficient to support the jury’s damage award and verdict. Circuit Judge Haldane Robert Mayer wrote a dissenting opinion arguing that the patents asserted by Sprint are invalid as a matter of law (Sprint Communications Co., L.P. v. Time Warner Cable, Inc., November 30, 2018, Bryson, W.).
