Duke University, another storied American institution that was named after the Duke family established the Duke Endowment, has been attempting for nearly a decade to federally register and protect trademarks for "Duke" in connection with a variety of goods and services, including alcohol and restaurant services.
John Wayne Enterprises, which still controls Wayne's intellectual property rights after his death, has also attempted to register "Duke" for alcoholic beverages. Duke University objected, citing a likelihood of confusion even though the college does not currently produce, market or sell alcohol, according to a Complaint.
