Shares of TiVo rose as high as 51 percent on Wednesday after a federal appeals court upheld a lower court decision that satellite broadcaster DISH Network and its parent, EchoStar Communications had infringed on TiVo's DVR patents. It ordered DISH to disable the infringing DVRs. DISH and EchoStar later issued a statement saying that they plan to appeal the decision to the U.S. Supreme Court and assured customers that the decision affects only a relatively few subscribers who have installed older DVRs and that it is replacing them "as quickly as possible." But TiVo said in a statement that the ruling "paves the way for TiVo to receive substantial damages and contempt sanctions regarding the DVRs that EchoStar and Dish Network failed to disable."
