This patent could have a chilling effect, but there's no way it would stand up in court. They can still use it as a bargaining chip. Court cases are expensive. And if you don't have a legal department, they are also a personal drain. But that's small fry. Financially, I don't believe it makes sense for them to resort to criminality to get such a patent. Maybe they hope it will influence their court case in Japan against Palworld?

It certainly seems that the patent office had discovered how lucrative kick backs can be.
