A federal judge kept TiVo Inc.’s patent suit against direct-broadcast satellite operator EchoStar Communications Corp. alive Wednesday, denying a motion to dismiss the case or transfer it to another jurisdiction.

TiVo alleges that EchoStar – which makes its own brand of digial video recorders – is violating its “time warp” patent.

TiVo says that patent covers methods of such basic functions as recording one program while playing back another and watching a show as it is recording.

The case is set for trial in October.
