Satellite companies DISH and EchoStar sue TiVo

DISH Network Corp and EchoStar Corp said on Friday they had filed a lawsuit against TiVo Inc and asked a Delaware court to find that their new DVR software does not infringe a TiVo patent. In January, the U.S. Court of Appeals said DISH, a satellite television provider, had infringed a TiVo patent in building digital video recorders, and upheld a lower court's damage award against DISH of $74 million plus interest. The appeals court in April denied DISH's request for judges to rehear arguments related to the patent dispute.
