The patent is the real deal. Each country has their own patent offices, and you have to file a patent in each country you want to protect your innovation in. As it happens, USA is the biggest market in the world for nearly everything, so most patents are filed also in USA. Though, the inventor's address is in USA, so it seems that Sony does R&D in many places. |
Im not so sure on the accuracy of that. Most if not all Nintendo patents occur in Japan, but hold equal weight oversees via the ITC
