What is a trademark?
- Any Word, Name, Symbol, Sound, Color, Design (or any combination thereof) used to identify and distinguish goods or services and to indicate their source.
- A service mark is the same as a trademark except that it identifies and distinguishes the source of a service rather than a product.
- Trademark registrations can be owned indefinitely. However, proper post-registration maintenance. Documents must be timely and accurately filed.

Trademark Searching
Conduct a trademark search to determine whether a conflict exists with registered federal marks or pending applied-for marks
Steps to Conducting a Trademark Search
If there is a registered U.S. trademark or prior-filed application for a mark that is not spelled exactly like your mark but is similar in sound, appearance, meaning or commercial impression, and used in connection with related goods and/or services, then the trademark will be refused registration. It is likely that consumers would be confused by similar trademarks for the same or related goods and/or services.
See the USPTO's page on the most frequently cited trademark registration refusals
The most common reason for refusal of a trademark registration is likelihood of confusion with other marks. Additionally, a trademark may also be refused if it lacks distinctiveness. In other words, it may be refused if the trademark is
- Merely descriptive for the goods/services
- A geographic term
- A surname
- Ornamental as applied to the goods

Common Law Trademarks
Even if a trademark is not registered federally, the owner may have common law rights resulting from the use of it. The owners of unregistered trademarks may indicate their claim to common law rights to the trademark by using "TM" with it.
