As someone who writes copyrighted material, and patents products, I have taken these excerpts from the USPTO office. Please check their website at www.USPTO.gov for clarification on any issues regarding your question.
"Copyright is a form of protection provided to the authors of “original works of authorship” including literary, dramatic, musical, artistic, and certain other intellectual works, both published and unpublished.The copyright protects the form of expression rather than the subject matter of the writing. For example, a description of a machine could be copyrighted, but this would only prevent others from copying the description; it would not prevent others from writing a description of their own or from making and using the machine."
"A TRADEMARK protects words, names, symbols, sounds, or colors that distinguish goods and services from those manufactured or sold by others and to indicate the source of the goods. Trademarks, unlike patents, can be renewed forever as long as they are being used in commerce." Typically a trademark is a logo of some sort.
A PATENT protects a product from being copied.
