A few sellers are selling fake Game&Watch items on eBay. Be careful when buying G&W! 
Nintendo did claim a few hundred patents. Some of them about Game&Watch. Most of them are from the inventor of Game&Watch, Gunpei Yokoi.

But it wasn't Gunpei Yokoi, it was Ichiro Shirai who invented it. Go to the article about G&W patents >>
