Consequently, in February 2011, Casey's General Stores Inc. filed a petition in a U.S. District Court in Des Moines, seeking a legal declaration that the word "footlong" does not violate Subway's rights.[107] Casey's further sought a declaration that the word "footlong" is a generic description of a sandwich measuring one foot.[108][109] Before serving its complaint on Subway, Casey's voluntarily dismissed its action, ending the litigation.[110]
