IA Labs CA's patent lawsuit against Nintendo has been dismissed by the District Court Judge presiding over the matter. The suit claimed that Nintendo's Wii Balance Board infringed on IA Labs' patent.
This patent was filed in 2002 and is described as:
A computer interactive isometric exercise system includes an effector, a sensor coupled at a selected location on the effector to measure a force applied by a user to the effector, where the applied force effects a strain on the effector, and control circuitry. The control circuitry includes a processor that receives and processes data corresponding to applied force information measured by the sensor for transference to a host computer.
In response to this victory, Rick Flamm, the senior vice president of Legal & General Counsel for Nintendo of America, said, "Nintendo has a passionate tradition of developing innovative products while respecting the intellectual property rights of others. We vigorously defend patent lawsuits when we firmly believe that we have not infringed another party’s patent. We refuse to succumb to patent trolls."
Nintendo's legal team seems to be quite busy these days with these "patent trolls". When the Wii U finally releases, it will be interesting to see who claims patent infringement on the controller.
