While Nintendos Wii U console sales continue to frustrate, its handheld gaming business offers hope of a better future. But even as its 3DS and 3DS XL consoles continue to outsell their rivals, Nintendo will have to come to terms with sharing a percentage of each sale with another company. In December, the company was told it must pay 1.82 percent of the wholesale price of each 3DS sold after it was found guilty of infringing on patented camera technology owned by Tomita Technologies.
