Patent Office Backs TiVo's DVR Claims

TiVo Inc. said the U.S. Patent and Trademark Office has reaffirmed the validity of all its patent claims for its “time-warp” digital video recorder technology in the second re-examination of the patent at EchoStar Corp.’s request.

TiVo’s shares jumped 9.7 percent to $10.08 in 4 p.m. Nasdaq trading, while EchoStar slid 1.1 percent to $19.30 and sister company Dish Network Corp. (DISH) fell 2.7 percent to $19.10.

“This decision by the PTO is final and not appealable by EchoStar,” TiVo said. It also expressed confidence a federal appeals court will uphold and enforce an injunction against EchoStar’s “ongoing willful infringement of the time-warp patent.”

EchoStar had no immediate comment Wednesday. Dish didn’t immediately respond to requests for comment.
