Nintendo, Ubisoft, THQ, EA Games, Majesco, Konami and Namco Bandai have all been named by industrial wire and cable company Impulse Technologies in a patent infringement suit over wireless exercise equipment.
Filed back in 1996, the company patented a pressure sensitive board with accelerometer accessory. The suit claims that with games like Wii Fit, Dance Dance Revolution, EA Sports Active and UFC Personal Trainer, these developers have infringed upon this technology.
However it's not just the games that IT is going after. It claims that as well as select titles, the Wii itself, WiiMotes and the balance board are all heavily influenced by the original 1996 patent. While these products are more developed than the original filing outlined, there does appear to be some merit to the claims.
It's not like the company has just sat back and not used the patents, either. Gamespot reports that Impulse Technologies is making use of the original technology in sports equipment marketed at gyms and training centres. Athletes work out in front of TV screens, using minigames and virtual trainers to take them through certain exercise routines.
It seems odd that Impulse has waited this long to file the claim, though perhaps it was waiting for as many publishers and developers to get on board as possible - maximising its potential payout.
This isn't the only lawsuit Nintendo has had to deal with recently, with ThinkOptics suing the gaming firm over the WiiMote, something that the company felt it owned the patent rights to - even though the patents in question were only filed after the Wii was launched.
