Subway recently threatened to sue Casey's, which has 1,600 stores, for using "footlong" to describe new made-to-order sandwich offerings, but Casey's filed its suit first, according to the Des Moines Register.
Subway's success in recent years has been driven in no small part by its "$5 footlongs." Subway's still-pending application for a trademark on "footlong" is being opposed by A&W, Pizza Hut, Kentucky Fried Chicken, Taco Bell, Long John Silver's and other restaurants, the Register reports.
