The U.S. Patent and Trademark Office (PTO) grants three basic types of patents: utility, design and plant. The PTO publishes patent applications to the public every Thursday. These provisional patent applications have generally been pending for 18 months prior to their release and are not yet approved. In addition to the PTO’s website, third-party online services, including Google Patents, provide patent application copies.

Other Methods for Requesting Applications

Step 1

Request an application by mail. Include the publication number for the application in your correspondence and payment for the appropriate fee, as specified in the fee schedule provided in the references section below.

Mail correspondence and payment to:

Mail Stop Document Services Director Of United States Patent and Trademark Office PO Box 1450 Alexandria, Virginia 22313-1450

Allow ample processing time for your request to be received and processed. Details about processing times and payment information can be found at the PTO website.

Step 3

Request an application in person. The PTO will not release a pending application that was published to a member of the public in person without written authority, known as a power to inspect. However, if the application has been abandoned, the application may be available for public inspection and copying through the File Information Unit (FIU). The FIU can be reached via telephone at (703) 308-2733.
