Re: Titles Question
You can trademark a name, which is different from copyright, but you have to be able to show that the name has not been in common use prior to your attempt to trademark it. And you usually trademark a name for a specific category, like a name you want to use for types of perfume (other people can then go ahead and trademark the same phrase for another category, like soap). Also, you are supposed to use the trademark symbol after it whenever you use the name or title or whatever from that time on to show that you are protecting your trademark. Otherwise, someone can come along and make the argument that the trademarked phrase has fallen into common use, like kleenex. Trademarking is expensive--IME, it can cost about $500 and that is without the help of a lawyer.
I have witnessed a couple of real long drawn-out battles over trademarked phrases. It is not pretty and talk about expensive.
