TiVo Inc. faces the possibility of having to defend a multimillion-dollar verdict it won in a patent infringement suit against EchoStar Communications Corp. while defending the validity of its patent on digital video recording technology.

On April 13, a federal jury in Marshall, Texas, awarded California-based TiVo nearly $74 million after finding that Colorado-based EchoStar, the parent company of the DISH Network satellite TV provider, had infringed on TiVo’s “multimedia time warping system.”
