You can register a logo with the USPTO by using the Trademark Electronic Application System (TEAS) or other online trademark service. If your logo includes design elements, you will need to upload an image, using a . jpg file, of the logo as part of your trademark application.
You can copyright your logo with the United States Copyright Office and file a trademark application with the United States Patent and Trademark Office (USPTO). Both processes are available online. To enforce your rights, monitor your business logo for unauthorized use.
