 It does take resources to challenge somebody else. The value of, for example, a trademark registration, though, is hopefully that you register your trademark and somebody else comes along after you and they also check and they say, okay, well, I'm not going to take that trademark because somebody else already has it. That's what we tell our clients. We check, we do a search. Somebody else has the same mark, then we'll steer them away from it. And so it protects you without you ever actually having to fight with somebody.
