in most countries, afaik, you actually can’t patent game mechanics, for the same reason you can’t patent rule sets for boardgames:
because they are essentially just logical connections. it would be like patenting math, which is also not allowed, for very obvious reasons. (with some very specific, very niche exceptions)
japan is just plain weird and wrong about their patent system.
that’s why all of the lawsuits about this stuff are happening in japan; not just because that’s where the companies are, but because japanese copyright law is (especially) fucked.
