Looking up those patents, the first alludes to a system where a player aims and fires an “item” toward a character in a field, and in doing so triggers combat, and then dives into extraordinary intricacies about switching between modes within this. The second is very similar, but seems more directly focused on tweaking previous patents to including being able to capture Pokémon in the wild, rather than only during battle. The third, rather wildly, seems to be trying to claim a modification to the invention of riding creatures in an open world and being able to transition between them easily.
Fuck Nintendo. They get a pass so often from people when they really shouldn’t.
Part of the reason is because most people don’t notice the lawsuits or think this is boilerplate legal stuff that happens in the background all the time. They’re too distracted by the entertainment side of things.
