Your keyboard includes a trademark symbol ( ™ ), a registered trademark symbol ( ® ), and a copyright symbol ( © ).
Use these symbols when you need them. Don’t use alphabetic approximations like (TM) or (c).
Trademark symbols are set as superscripts — smaller characters positioned above the baseline of the text (Roxy’s Pizza™, Caring Is Our Business®). If you use proper trademark symbols, they’ll appear at the right size and height. No space is needed between the text and the trademark symbol.
Copyright symbols appear in line with the text (© 1999). Use a nonbreaking space between the copyright symbol and the year to ensure the two don’t end up on different lines or pages.
To dispel an urban legend that persists among many civilians, and more than a few lawyers: with respect to newly created works, the copyright symbol has no magic powers. Putting a copyright symbol on something you made does not grant you a copyright. Nor does failing to use it deprive you of a copyright.
