TiVo Wins Patent Validation

The U.S. Patent and Trademark Office ruled against EchoStar Communications, a company that recently challenged the validity of TiVo's time-warp patent. The company has to fork over $90 million to TiVo. Ouch.

EchoStar was disappointed in the U.S. Patent and Trademark Office decision but said the agency's conclusion won't affect its pending appeal of a court ruling in TiVo's favor. The court decision requires it to pay TiVo $89.6 million in damages for patent infringement and to stop distributing DVRs or to modify features of its products.
