Looks like it’s over the game mechanics of ‘releasing a creature into a 3d environment and having it perform a contextual task’ & ‘having a rideable mount switch to a different rideable mount depending on terrain’
I don’t think either of these would work in the US, because you can’t protect game mechanics here, but I’m not sure about Japan’s take.
Edit: I missed that this was still under speculation at the time of the post:
Based on searching of Japanese patent databases, initial speculation is that these may include (but is not necessarily limited to) patents relating to game mechanics and gameplay features from Pokémon: Legends Arceus, and may include patents such as one for throwing and using Poké Balls in a 3D space (JP,2023-092953,A); and one for automatically switching between ride Pokémon as a player transitions between different terrain, such as between air and the ground (JP,2023-092954,A).
They are suing over a patent though (ie, a technology). What you are talking about is a copyright suit.
Unfortunately we don’t know what patents Nintendo is suing over. And I struggle to think of a patent issue that would generate a good faith claim.

Kinda wild that you could patent a super basic mechanic that pretty much anyone could come up with
