DVR Showdown Continues

Dish Network and EchoStar, two separate companies since December, said that they have sued TiVo, thus causing the latest wrinkle in their 4-year-old legal dispute over DVR patents.

Friday’s lawsuit asks a Delaware judge to find that Dish’s newest DVR software no longer infringes TiVo patents.

TiVo already proved to a court and an appeals court that Dish has been infringing, but more recently, Dish has maintained its DVRs were sent software upgrades that make their devices non-infringing.

The difference is huge to both parties considering that a Texas judge ruled months ago that Dish should disable about 4 million DVRs.
