PTO Invalidates TiVo Patent Claims, but Case Against EchoStar Is Far From Over

The U.S. Patent and Trademark Office has invalidated software patent claims that TiVo Inc. used to win $200 million in sanctions and infringement damages against EchoStar Corp., but TiVo is digging in to continue the legal fight. 

TiVo has been waging its patent infringement battle over digital video recorder technology against EchoStar since 2004. 

On Tuesday, EchoStar Corp. and its technology partner Dish Network Corp. announced the PTO's final office action on a TiVo patent they challenged. The PTO ruled that two pieces of prior art -- evidence of prior inventions using the same technology -- made the software claims in TiVo's patent invalid. The PTO ruling represents yet another setback for TiVo, following a ruling against it last month at the U.S. Court of Appeals for the Federal Circuit.
