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.
I’m not saying ignore it, it’s a valid reason to not like the game, like any other subjective reason.
I’m saying calling the game “Pokemon with guns” is dismissive of what the game is. It’s like calling Minecraft “Rust with animal husbandry”, which completely misses what the game is about.
