cooler says: "Using the example of Marvel Comcs & "mutant". Assuming they have trademarked the term they can only restrict it's use WRT to comic books & the characters involved. Legally there is nothing they can do if I want to open a chain of restaurants named "Mutantburgers"."

Well, I'm going to assume you know a lot more about this than I ever will. Tho I probably used the wrong terms my facts were valid/true. Marvel has copyrighted (or 'trademarked') the word 'mutant'. And if 'Mutantburgers' came anywhere near what they thought was an infringement on their property, don't think they wouldn't try to stop you. Trust me on this. I have a letter from their lawyers in my basement threatening to sue me for a minor infraction of one of their characters. kmw
