TiVo and Dish could be headed back to court... again

You didn't really think the patent dispute between TiVo and Dish Network (formerly known as EchoStar) was over, did you? Well, apparently some lawyers at Dish Network didn't think so either, because they've filed a petition to have an appeals court hear the case over again.

Earlier this year, that federal appeals court upheld a lower court ruling that found EchoStar had violated several TiVo patents. But Dish is claiming that one of TiVo's witnesses in the case made inconsistent statements, and that the case should be reheard.

So that means the two companies could be headed back to court for the umpteenth time. While each side has undoubtedly spent a bundle on legal fees, nearly $90 million is at stake.
