Please tell me you are joking. This isn't the case of some Patent Troll licensing an obvious technology then sitting on it til someone develops it.
Tivo is a company that built an incredible device that everyone wants to copy. This is EXACTLY the kind of thing a patent is meant to protect. AT&T stole Tivo's idea and is now making a profit on selling it, acting as a direct competitor to Tivo using Tivo's own patented ideas.
If suing for patent infringement "should not be tolerated", what is Tivo's recourse?
