A logo, like any other artistic image, is protected by copyright law as soon as it's drawn, but registering the copyright for your logo with the U.S. Copyright Office allows you to enforce the copyright in court, and it is simple enough to do by yourself. Registering the copyright on your logo won't protect your business from others who manufacture knock-off goods sold with a similar logo. Registering your logo as a trademark with the U.S. Patent and Trademark Office in addition to registering a copyright of the design will further protect your business.
Access the U.S. Copyright Office webpage and check the current fee schedule for electronic filing. The fees change regularly. Electronic filing is much less expensive than mailing in the hard copy forms, even when you are filing hard copy renderings of artwork.
Click on the electronic copyright registration icon on the main screen of the website and complete the online form required for a basic filing. Indicate that you will be submitting your materials for deposit by hard copy and make the appropriate online payment based on the fee schedule. Submit the electronic filing form.
Mail two copies of your logo artwork to the U.S. Copyright Office at the address shown on the form you completed on their website. You will receive an email or a hard copy certificate of registration; the copyright registration is valid as soon as it is received by the U.S. Copyright Office.
