Japanese inventor Seijiro Tomita has filed a lawsuit against Nintendo on the grounds that he claims to have invented the glasses-free 3D technology used in the 3DS. He argues that he met with Nintendo and demonstrated the parallax barrier technology in 2003, eight years before the console’s release. If successful, Tomita’s attorney says the inventor could be entitled to damages worth $9.80 per handheld, equating to around $25 million total.
Nintendo alleges that the meeting with Tomita was one of hundreds and that it did not eventually use one of the key features of his technology: cross-point, which allows the generation of 3D images across multiple screens. The matter would not be the first time Nintendo’s patents have been challenged; in 2008, the company was ordered to pay $21 million damages to Texas-based Anascape Ltd. over the design of the GameCube controller, but the ruling was ultimately overturned by the US Court of Appeals.
