Title 35 › PART II — PATENTABILITY OF INVENTIONS AND GRANT OF PATENTS › CHAPTER 11 — APPLICATION FOR PATENT › § 122
Keeps patent applications secret at first, but usually makes them public 18 months after the earliest filing date. An applicant can ask to publish sooner. The Patent Office Director controls what published information the public can see, and that decision is final. Some applications are not published: ones that are no longer pending, those under a secrecy order for national security, provisional applications, and design patent applications. If an applicant certifies at filing that they will not file the same invention in other countries that require 18‑month publication, the Office will not publish. The applicant can cancel that request anytime, but if they later do file abroad they must tell the Director within 45 days or the U.S. application will be treated as abandoned. If the applicant cancels the non‑publication or files abroad and notifies the Director, the application will be published as soon as practical. If foreign filings have less detail than the U.S. filing, the applicant may give a redacted U.S. copy for publication, but it must be filed within 16 months of the earliest filing date or the full application may be published. A special timing rule for patent term adjustments won’t apply to a claim if the redacted publication doesn’t let a skilled person make and use the claimed invention. No one can start a protest or other pre‑issuance challenge after publication unless the applicant gives written consent. If publishing would hurt national security, the Director must keep the application secret and follow national security procedures. Any third party may send the Office patents, published patent applications, or other printed publications that might matter for examining an application, as long as the submission is in writing before the patent is allowed and no later than either 6 months after publication or the first time an examiner rejects any claim, whichever is later. Those submissions must explain why each document matters, include a fee, and include a statement that the submitter followed the rules.
