i don't think you are quite right. You are thinking more of a patent, which you wouldn't have cause you didn't invent it. Here's a quote from the us copyright site: Copyright, a form of intellectual property law, protects original works of authorship including literary, dramatic, musical, and artistic works, such as poetry, novels, movies, songs, computer software, and architecture. Copyright does not protect facts, ideas, systems, or methods of operation, although it may protect the way these things are expressed. http://www.copyright.gov/help/faq/faq-general.html#protect Best you can do is when you sign up for shows, tell them you don;t want her anywhere near you because she copied your exact product, and you have proof, sometimes they may end up not letting her in the show...ask me how I know...I did that to some one, who did the same to me.
