Dish Network has petitioned the federal appeals court to rehear their appeal in the TiVo patent dispute. They’re claiming an expert witness who testified for TiVo contradicted himself, and therefore the software infringement verdict was not“supported by substantial evidence.” This doesn’t mean anything just yet, the court court deny the petition, or they could agree to rehear the case. And, if they do, it doesn’t mean the results will change. The saga just continues to drag out. If TiVo manages to prevail again, it will mean a higher reward from Dish as interest continues to accrue.
