An easy way to remember the difference between a copyright and a trademark is to break the word in half.

Trade mark. A mark used in trade.

In other words, a trademark is your stage name, the name of your company or product, the logos you use to identify these things with, and other things of that nature. 

Our firm can help you decide whether you should register your trademark with the state or with the United States Patent and Trademark Office (USPTO) and handle the registration for you.
