In the latest development in the ongoing legal saga between TiVO and EchoStar, a U.S. district court judge has lifted a stay of a patent infringement lawsuit that EchoStar filed against TiVO in the wake of TiVO’s original patent suit against EchoStar. TiVO first filed suit against EchoStar in 2004, alleging that digital video recorder (DVR) set-top boxes manufactured by EchoStar for use by DISH Network direct broadcast satellite customers infringe upon TiVO DVR “time warp” patents. Two years later, a jury ruled in favor of TiVO, prompting EchoStar to develop a technology workarounds in its DVR products that avoid infringement of the TiVO patents in question. Claiming, however, that EchoStar’s workarounds continued to violate TiVO’s patents, TiVO later convinced the U.S. District Court for the Eastern District of Texas to hand down an injunction against the sale and marketing of EchoStar DVR products that contain patented TiVO technologies and to award TiVO an additional $1 billion in damages. That order is currently under review by an en banc panel of the Federal Circuit Court, which also stayed the lower court injunction pending a decision on EchoStar’s appeal. Meanwhile, EchoStar’s 2005 countersuit against TiVO accuses it of violating EchoStar technologies that control how multimedia files are formatted, accessed and stored on DVR devices. Although EchoStar’s original complaint alleged violations of four patents, only one of those claims is currently active. The EchoStar suit has been stayed by the district court since 2006, and the court’s decision this week to lift that stay enables the U.S. Patent and Trademark Office to proceed with a reexamination of the patent that remains in dispute. Applauding the court’s decision, a DISH spokesman said, “we look forward to the trial.” Charging that EchoStar acquired the patent in question from IBM after TiVO filed its original lawsuit against EchoStar, TiVO predicted that the reopening of EchoStar’s suit would have no effect on the case before the Federal Circuit.
