It appears that all three of the game console makers, Microsoft, Sony and Nintendo are facing a patent lawsuit from a patent holding company for the way they designed their controllers. The patent in question is for a low-voltage joystick interface -- though, the fact that all of the game consoles on the market today use a similar technique suggests it's not a particularly non-obvious idea. As the link above notes, the patent holding company has been involved in a few other high profile patent lawsuits, but hasn't done so well with a few of them. Apparently, though, that's just incentive to keep on trying.
