Harley Davidson - Sound of Engine Roar
Oftentimes companies trademark sounds, such as NBC did with its famous three-tone jingle. One of the more peculiar trademark requests of this type occurred in 1994 when Harley Davidson tried to register the sound of its motorcycles’ revving engines. The company’s registration description read that “The mark consists of the exhaust sound of applicant’s motorcycles, produced by V-twin, common crankpin motorcycle engines when the goods are in use.” The application was denied, however, after nine other motorcycle manufacturers complained, citing the fact that they all used V-twin crankpin engines that produce the same sound.
