How does the USPTO handle confidentiality for international applications filed in the United States?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

The United States Patent and Trademark Office (USPTO) has specific procedures for maintaining the confidentiality of international applications filed in the U.S. According to MPEP 110, which references 35 U.S.C. 368, International applications filed in the Patent and Trademark Office shall be subject to the provisions of chapter 17. This means that such applications are subject to the same secrecy provisions as regular U.S. patent applications. Additionally, If a license to file in a foreign country is refused or if an international application is ordered to be kept secret and a permit refused, the Patent and Trademark Office when acting as a Receiving Office, International Searching Authority, or International Preliminary Examining Authority, may not disclose the contents of such application to anyone not authorized to receive such disclosure. This ensures that sensitive information in international applications is protected in accordance with U.S. law.
