Nintendo is being sued for alleged patent infringement for the glasses-free stereoscopic 3D technology used in the 3DS. The company bringing the lawsuit is Tomita Technologies, founded by inventor Seijiro Tomita. He worked for Sony for 30 years before founding the company.
Tomita holds over 100 patents, and is the inventor and co-inventor on almost 70 patents. The patent involved in the suit is U.S. patent number 7,417,664, specifically for “stereoscopic image picking up and display system based upon optical axes cross-point information.” Third parties have licensed the tech, but Nintendo is not one of those parties.
Tomita is suing for damages from Nintendo’s “deliberate and willful” infringement and legal fees. He also wants the court to find that Nintendo intended to infringe on the patent.
