Pocketpair goes on to say that Palworld has been claimed to infringe on three patents held by Nintendo and The Pokemon Company and that part of the damage is required as compensation.
The first patent is one that most had guessed to be part of the case, as 7545191 refers to the process of capturing and befriending Pokemon, which Palworld apes with its Pal Spheres. The other two patents that are included in the lawsuit, 7493117 and 7528390 haven’t been found and detailed just yet, but they’re likely also mechanics in Pokemon games that are replicated in Palworld.
What I always hear is that companies will send C&D letters to small ventures, because it creates precedence. Without that, a company loses the right to sue.
I wonder how true that actually is.
That’s more trademark law, not patent or copyright. At least in the US, I don’t know if Japan is different.
