A federal judge in Seattle has dismissed a patent infringement lawsuit against Nintendo of America, which claimed that the company's Wii MotionPlus peripheral violated a patent owned by Triton Tech of Texas.

Originally filed way back in the prehistoric times of 2010, the lawsuit named both Nintendo and Apple as defendants, alleging that both companies had violated its patent, No. #5,181,181: "Computer apparatus input device for three-dimensional information."

The abstract, available in full here, describes a device that uses accelerometers and rotational sensors to calculate movement across three dimensions, and then wirelessly transmit that data back to a central computer. While that does sound like a dead ringer for the Wii MotionPlus when put in a nutshell like that, there was evidently enough minutiae in the patent's full-length definitions to keep Nintendo in the clear.
