>do regulators know that for a fact before they decide no to enforce penalties for what you are claiming is trademark infringement?
The regulator doesn't pursue trademark infringement cases. It is upon the trademark holder to defend their mark via proceedings. So WingstopCo would bring an action against ThighstopCo. In this case, since both marks are held by the same entity, there's no enforcement possible unless the holding entity an exclusive license to one of the marks to another party.
