The trademark symbol appears as the letters "TM" in a superscript font. Typing the trademark symbol next to symbols, designs or words indicates that you consider yourself the owner of those unique symbols, designs or words. You do not have to register the images or words to use the trademark symbol. If you register a trademark with the United States Patent and Trademark Office, the symbol appears as an "R" within a circle. You can type either version of the trademark symbol using the keyboard of your MacBook.
