The Wii utilised common technology in clever ways and sold over 100 million units - that's the perfect combination to prompt a whole lot of patent-related court cases. Nintendo has successfully defeated the majority of patent claims against it in recent years, and has now confirmed the end of another case.

This time around Motion Games, LLC had appealed against a decision to invalidate its patent claim against the Wii Remote, and that appeal has been rejected. It's another solid win for Nintendo's legal team, though the press release deviates from some of the usual language to criticise the tactics of Motion Games during the legal process. The big N was particularly unhappy at demands for senior executives to appear in court, for example - an excerpt from the press release is below.

Motion Games' patent described cameras and systems that track assembly-line components, such as car parts. Motion Games asserted that the Wii Remote infringed that manufacturing patent. During the litigation, Nintendo successfully overcame numerous needlessly burdensome discovery demands from Motion Games, including improper demands to interrogate top-level executives.

"We are very pleased with the court's confirmation that Motion Games' patent is invalid and never should have been granted," said Ajay Singh, Nintendo of America's Director of Litigation and Compliance. "Litigation tactics cannot save an invalid patent, and such attempts only underscore the need for patent reform that reduces unnecessary burdens on defendants. Nintendo has a long history of developing innovative products, and will continue to vigorously defend those products from patent lawsuits."

That's another case down in the ongoing patent battles for Nintendo's legal team.
