#2. "RE: Trademark for all businesses" In response to Reply # 0
Without checking, I would imagine that you'd not be able to trademark "Intelligence Agency" and even if you could, it wouldn't be a very strong mark. The strongest marks are words or combinations of letters that are not in the common vernacular or are not words at all. Look at some famous trademarks. Ebay (which doesn't mean anything) is a stronger mark than Apple. Make sense?
