In a decision made on April 24th of this year, the Nintendo 3DS patent infringement case's verdict made in 2013 has been overtuned.
The decision from a federal judge states that the 3DS does not infringe a patent on 3D display technology originally asserted against Nintendo by Tomita Technologies USA and Tomita Technologies International.
Specifically the ruling found that the "3DS performs in a significantly different way and does more than was contemplated by the Tomita patent."
The news was first announced by Japanese newspaper Nikkei in a follow-up article concerning the decision (credit to ZhugeEX for the screenshot):
