Did you know that Nintendo was embroiled in a patent case against them since 2008?
Neither... did I !!!11!!!1!
Well... they won. Surprise.
A jury figured that none of Nintendo's controllers offended against Anascape Ltd. This actually reversed a decision that a lower court made back in '08 that some of the Big N's older human interface devices (and the Wii classic controller) did infringe on patents granted to the plaintiff.
So good for them.
