VRROOM, VRROOM! Now hear this! The Harley Davidson company is asking the government to register the sound its motorcycles make as a trademark. Trademarks legally protect businesses from having their products copied by others. A trademark on the Harley sound would make it illegal for other motorcycles to copy the unique roar of a Harley engine.
If that sounds strange, listen up: NBC trademarked the three chimes you hear with its name on TV, and the MGM movie company did the same with its lion's growl. So don't copy that cat--it's against the law!
