As with copyrights, legal rights to trademarks arise automatically without governmental formalities. But unlike copyrights, trademark rights don't begin at the moment a word, symbol, or phrase is first scribbled on paper. Rather, trademark rights stem from the actual use of a distinctive mark in commerce. If you develop a catch phrase, you should register it with the US Patent and Trademark Office (USPTO).
