How do Japanese patents differ from USA/CAN? My general understanding of patents is that they expire after 20 years - Pokemon is older than that. Do Japanese patents have a longer duration? Did Nintendo patent a game later than the originals?
I’m not patent savvy - of they are only granted this year (as a point of origin for the patents’ eventually expiry), wouldn’t the years of previous Pokemon games invalidate these patents due to prior art?

These patents were granted to Nintendo this year.
