A Las Vegas business owner faces a legal fight over a word most of us use every day.

One glance at the Las Vegas Strip makes it clear that Southern Nevada is a center of creativity. New ideas, catchy phrases and eye-catching displays battle to attract attention. But the city also is a danger zone for thieves who hope to profit from that creativity by appropriating protected trademarks or concepts for their own use.

Well the question isn't exactly who owns the Cavern Club. That's the original club in Liverpool where the Beatles performed before they were really famous. The Hard Rock Hotel owns the rights to the name in the United States and has created a Cavern Club in its Las Vegas hotel. So how can the name be owned in some places by one company and other companies in other places? A federal lawsuit is set to decide who really owns the name "Cavern Club."
