Title: Sound trademark
Passage: More famously, Harley-Davidson attempted to register as a trademark the distinctive ``chug'' of a Harley-Davidson motorcycle engine. On February 1, 1994, the company filed its application with the following description: ``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.'' Nine of Harley-Davidson's competitors filed oppositions against the application, arguing that cruiser-style motorcycles of various brands use the same crankpin V-twin engine which produces the same sound. After six years of litigation, with no end in sight, in early 2000, Harley-Davidson withdrew their application.
