You may remember (if you have a watertight memory) a lawsuit arising a few years ago between Nintendo, Microsoft and a third company named Anascape, who sued both hardware manufacturers for apparently infringing their patents. Anascape won that time, netting a cool $21m from Nintendo and an undisclosed sum from Microsoft. Now, two years later, Nintendo has successfully overturned the decision through the appeals court.
It turns out now, in this recent court's opinion, that none of Nintendo's accessories infringe on Anascape's patents, though it's unclear whether this means Nintendo will receive its $21m back. Fingers crossed though, eh?
