Lanham/Trademark Act

The Lanham Act defines the statutory and common law boundaries to trademarks and service marks. Trademarks (and service marks) are words or designs used in the advertising of goods and services. Rights to use a trademark are defined by the class(es) for which the trademark is used. Therefore, it is possible for different parties to use the same trademark in different classes. The Lanham Act defines the scope of a trademark, the process by which a federal registration can be obtained from the Patent and Trademark Office for a trademark, and penalties for trademark infringement. The Legal Information Institute provides Title 15 of the US Code, which encompasses the Lanham Act.
