Rick Flamm, Nintendo of America's senior vice president of Legal & General Counsel, has spoken out against "patent trolls" after winning a third litigation case this year.

Californian firm IA Labs claimed that the Wii Balance Board and Wii Fit software infringed on U.S. Patent No. 7,121,982. IA Labs' patent covers:

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.

Patent images show a rowing machine-like apparatus, quite different from Nintendo's now iconic Balance Board. A Maryland U.S. District Court judge dismissed the lawsuit without the need for a jury trial, to which Flamm 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.

Trolls everywhere.
