Kirk Sigmon is an attorney at Banner Witcoff , and an expert in patent law.

He joins us this week to make sense of the wild, and complicated situation in which Nintendo and The Pokemon Company are posturing towards US litigation against Pocketpair, the maker of Palworld. Litigation in Japan is already underway.

In the process, Nintendo has secured patents for game mechanics that look a lot like what we've already been playing for the last 30+ years.

There's patent activity relating to mounts and the quick-switching of mounts. There are patents about throwing an object to capture a character. And very recently, a new patent was secured that covers the summoning of a character.

This is a complicated and niche field, so we first cover some basics of patent law, before getting into the dirty details of what's been called "by far the most aggressive patent enforcement any game maker ever attempted against a rival."
