DISH Network suffered yet another defeat in its quest to fend off patent infringement charges levied by TiVo, Inc., as a three-judge panel of the U.S. Court of Appeals for the Federal Circuit upheld a lower court ruling that digital video recorder (DVR) technology workarounds developed by DISH affiliate EchoStar in response to an earlier court ruling violate a permanent injunction barring DISH from using TiVo-patented technologies. Yesterday’s ruling clears the way for TiVo—the pioneer of DVR “time warping” technology that enables viewers to pause, rewind and replay live television programs—to collect from DISH at least $300 million in contempt sanctions, damages and interest that were awarded to TiVo last year by the U.S. District Court for the Eastern District of Texas. Although two members of the appellate panel determined that the district court applied the correct standard in concluding that the DISH workaround continued to infringe TiVo patents, the lone dissenting judge proclaimed that the majority’s ruling punishes a company that had made a good faith effort at redesigning its DVR product to comply with earlier court directives. Seizing upon that dissenting opinion, DISH said it would seek an en banc hearing before the full panel of appellate judges as it added that it would also propose “a new design-around to the district court for approval.” Noting that the $300 million award only covers DISH infringements through July 1, a TiVo spokesman said his company would pursue additional damages for infringements after that date.
