Based on the law invoked it seems the idea might be that his versions of the games essentially piggy-back off the trademarks attached to Pokemon, while effectively rendering the vanilla, unmodified cartridges such that they may be perceived to be an inferior product in comparison, despite being the original product. This seems like a stretch even under Japanese law, since the article gives the impression that he was not selling the cartridges themselves, but merely the service of taking cartridges and modifying them. But Japanese copyright law is kinda crazy. There's a reason that Japanese Wikipedia is almost totally bereft of images.
