It’s important to distinguish between copyrights and trademarks, so that you can select the right option for you.

Copyrights protect and are granted to individuals
(or groups of individuals) who create something new and unique, such as a book, song, or artistic work of art. Web pages, research papers, poems, and photographs can be copyrighted as well. A copyright can only be applied to an original work of creative expression. You cannot obtain a copyright for an idea, method, a non-unique lists of items, the alphabet, or any other work that you yourself did not create.
Trademarks are not unique, never-before-thought-of works of expressions. Trademarks are words, names, symbols, logos, and the like that are used by companies to distinguish their brand. While a trademark does protect a brand though, it does not protect another person from creating the same product (only a patent can protect that). You may want to refer to The Difference Between a Patent and a Trademark if you aren't sure.
