Question: Artist's Copyright FAQ: Is a Copyright Symbol Essential?
Answer: No, though it does make it very clear for people unfamiliar with copyright law. To prevent the defense of "innocent infringement", use the copyright symbol, date of creation, your name, and if you want, the words "all rights reserved". You don't have to be registered with the US Copyright Office to use the copyright notice.
