Federal appeals court upholds Nintendo's win in 3DS patent battle
Just months after the Nintendo 3DS launched in 2011, it faced patent infringement allegations. Tomita Technologies was accusing Nintendo's new handheld of using its glasses-free 3D display technology without paying royalties. Like most patent lawsuits, it dragged on for years -- first awarding a victory to Tomita before handing the win to Nintendo in appeals. Now, a higher court has confirmed Nintendo's victory. On Friday, the Federal Circuit court ruled that the Nintendo 3DS does not infringe Tomita's patent.
