Burger King
The Burger King — unrelated to the Florida-based fast food chain Burger King — is a Mattoon restaurant whose owners claim it is the "original" Burger King. In 1968, they sued the national chain Burger King, producing a well-known case in United States trademark law. The federal 7th Circuit Court of Appeals ruled that federal trademark registration has priority over state law, giving the national Burger King chain rights to the name beyond a 20-mile radius around the original Burger King. Today, the closest Burger King franchise location is 25 miles away in Tuscola, Illinois.
