Where should confidential materials be delivered at the USPTO?
To ensure proper handling of confidential materials, the MPEP recommends hand-delivering them to a specific location:
In order to ensure that such an envelope or container is not mishandled, either prior to reaching the Office, or in the Office, the envelope or container should be hand-carried to the Customer Window located at: U.S. Patent and Trademark Office Customer Service Window Randolph Building 401 Dulany Street Alexandria, VA 22314
Alternatively, if hand-delivery is not possible, the materials can be mailed to:
Commissioner for Patents, P.O. Box 1450, Alexandria, VA 22313-1450
By following these delivery instructions, you can help ensure that your confidential materials are properly received and handled by the USPTO.
