Patent Office Upholds TiVo Patent; EchoStar Appeal Still Pending

Alviso, Calif. -- TiVo, the Alviso-based provider of digital video recorders and programming services, said that the U.S. Patent Office has upheld its "Time Warp" patent on digital video recording technology after a reexamination was requested by rival EchoStar. TiVo is suing EchoStar for infringing the patent on its recorders. Though EchoStar won't be able to appeal the PTO's decision, it won't impact EchoStar's separate appeal of a federal court ruling, which found the company guilty of patent infringement. EchoStar is the operator of the DISH Network satellite TV service.
