As far as I am aware... Copyrighting only covers creative works, such as words, images, movies, etc... Patents are for ideas. You can't copyright an idea.
As far as trying to steal a domain by acquiring a TM before them, well thats just low and I doubt it would work unless you can prove that you used the name in commerce prior to them. Even then, they may be able to use it, because TMs only cover specific categories.
