Legal Question in Intellectual Property in Michigan

You likely can sue them under your state's trademark law.

Trademark law is NOT do-it-yourself law. Start a lawsuit by contacting an INTELLECTUAL PROPERTY attorney admitted in your state. You can find a listing of IP attorneys at https://oedci.uspto.gov/OEDCI/ ; enter your state and the first three digits of your zip code to bring up local practitioners. Make sure the person you go to is an ATTORNEY, not an agent; agents are non-attorney patent practitioners who are admitted only before the US Patent & Trademark Office. Attorneys can represent you in court; agents can't.
