Tech developer Impulse Technology -- that name sound familiar? -- has filed a lawsuit against Nintendo and a score of third-party studios, accusing them of violating a 1996 patent for an "interactive system for measuring physiological exertion." The suit is largely based on the weight-tracking Wii Balance Board (and the games which use it, like Wii Fit Plus, Zumba Fitness 2 and UFC Personal Trainer), which Impulse claims too closely resemble its own Trazer Interactive Fitness machine.

Normally, we'd scoff at such a lawsuit, especially since Impulse leveraged almost the exact same claims against Microsoft for its Kinect hardware this past July. Still, take a look at the Trazer Interactive Fitness machine, seen above. The resemblance truly is uncanny, right?

Right?
