I'm not a lawyer. I assume you;ve read the wikipedia article on copyright[^]
What do you mean by "use"? If you create something then you control how it's distributed, so if you don't want someone using it, don't distribute it.
A trademark protects the mark's use for commercial purposes - it doesn't mean it can't be used in places (such as an article about the product) where there's no chance of there being confusion about whether you're using the name for commercial purposes or just talking about it.
I think what you're after is a License agreement. Get a lawyer if you're concerned, or pick a common license[^]
