Back in 2006, TiVo filed a patent infringement lawsuit against DISH Network, claiming that DISH s DVR was a violation of a patent held by TiVo. The courts found that to be correct and recently denied DISH their appeal request. DISH is moving on to the Supreme Court with its appeal but in the meantime has filed a lawsuit against TiVo regarding DISH s new DVR software. TiVo has been making public statements that the new technology also infringes on a TiVo patent and DISH wants a judge to confirm that it does not. TiVo hasn t commented on the lawsuit.
