Realize, though, tht if someone infringes on your TM you better hope they don't have more money than you do becasue you will have a hard time suing them and being successsful. It's a lot like patents. Sure, you can patent and invention, but if, say, Proctor and Gamble comes a long and decides to steal your idea and profit from it, you will be hard-pressed to get anything done about it unless you have the money to pursue it legally.
