In the U.S., trademark law regulates registered and unregistered trademarks. It also regulates service marks, although service marks have less legal authority. Trademark law protects the creator of a unique phrase, design, image, word, name, or logo so that other legal entities cannot use them.
Registered and Unregistered Trademarks

Trademark law honors unregistered trademarks as well as those that are registered. Registered trademarks are designated by an R with a circle around it. Unregistered trademarks are designated by a TM.

Even though they have not been registered, common law trademarks are enforceable. They do not, however, offer the exact same level of protection as those that are registered.
Differences in Trademark Law for Registered and Unregistered Trademarks

Trademark law gives more authority to registered trademarks. For instance, a company that uses a registered trademark can prevent anyone else from using it regardless of where they are located. Unregistered trademarks, however, only prevent other companies from using logos, phrases, or designs when they are in within certain geographic boundaries.

Trademark law also makes it much easier for those who register to protect themselves from infringement.
