(USATODAY) — “I never trust a man that doesn’t drink,” John Wayne famously said. What about a university?

The family of legendary actor John “The Duke” Wayne is suing Duke University over the use of the word “Duke” in a trademark for alcoholic beverages.

John Wayne Enterprises, run by the Wayne family, filed for a trademark application last year to use the word on alcoholic drink labels, except for beer.

Duke University, located in North Carolina, objected to the trademark. The school argued there could be a “false suggestion of a connection” between the labels and the school, according to a complaint by the Wayne family filed July 3 in a U.S. district court in California.
