I’m not a lawyer but, I know when you file for a patent you can do that in just one country or internationally (which is significantly more expensive). Skimming through the Wikipedia article it seems to be talking about that, but first you need to have filed for the patent internationally and not in just one country.
From what I’ve read about this topic, it sounds like this is a patent active in Japan only.
Isn’t this the scenario the Patent Cooperation Treaty was intended to resolve?
