copyright, patent, trademark, which one?

Need to know what to use for proctection of a name/logo for a private organization (motorcycle club) that is just getting started. We have paid an artist to create a logo and want it protected. We also plan to use the name for a business in the future. Help Please!!!!

I am a law school graduate. What I offer is mere information, not to be construed as forming an attorney client relationship.

How do I find out if I need patent, trademark and/or copyright protection?

Patents protect inventions and improvements to existing inventions. Copyrights cover literary, artistic, and musical works. Trademarks are brand names and/or designs which are applied to products or used in connection with services.
