A company founded by a former Sony engineer is suing Nintendo for patent infringement over the 3DS’s glasses-free technology.
Law360 reports Tomita Technology’s founder holds U.S. Patent No. 7,417,664 for “Stereoscopic Image Picking Up and Display System Based Upon Optical Axes Cross-Point Information.”
This patent reportedly concerns “technology relating to displaying stereoscopic images on-screen for viewing with the naked eye, i.e., without utilizing glasses or other devices.”
Tomita’s filing alleges the 3DS infringes this patent, which he applied for in 2003 and received in 2008.
Tomita holds over 70 patents and has applied for more than 100. The company is based in Japan and the US.
