The Nintendo 3DS uses glasses-free 3D technology that infringes on a patent held by a former Sony engineer, according to a lawsuit filed two weeks ago.

Seijiro Tomita, the founder of Tomita Technologies and holder of a glasses-free 3D patent, alleges that neither Nintendo nor Nintendo of America have appropriate licensing to use his invention in the 3DS. He holds patent no. 7,417,664 in the United States and the same patent in Japan.

In addition to an injunction against Nintendo, Tomita seeks damages, legal fees, and a finding that the infringement was "deliberate and willful."
