Title 35 › Part PART II— - PATENTABILITY OF INVENTIONS AND GRANT OF PATENTS › Chapter CHAPTER 11— - APPLICATION FOR PATENT › § 122

Last updated Apr 6, 2026|Official source

Summary

The Patent Office must keep patent applications secret unless the applicant agrees or the law or the Director needs to share information. Most patent applications are made public by the Office 18 months after the earliest filing date the applicant claims. An applicant can ask to publish earlier. The Director decides what published information the public can see and that decision cannot be reviewed. Some applications are not published: ones that are no longer pending, ones under a secrecy order, provisional applications, and design patent applications. An applicant can ask at filing that the application not be published by certifying they have not and will not file for the same invention in another country or under an international agreement that requires 18-month publication. That request can be canceled anytime. If the applicant later files abroad, they must tell the Director within 45 days or the U.S. application will be treated as abandoned. If they cancel the request or notify the Office of a foreign filing, the application will be published as soon as practical. If foreign filings show less detail than the U.S. filing, the applicant may send a redacted U.S. copy that removes parts not in the foreign filings. The Office may publish only the redacted copy unless it is not received within 16 months of the earliest filing date. Certain claim protections do not apply if the redacted parts do not let a skilled person make and use the claimed invention. The Director must also set rules so no one can start a protest or pre-issuance challenge after an application is published without the applicant’s written consent. If publishing an application would harm national security, it will not be published and will be handled under the secrecy rules in chapter 17. Any third party may submit patents or printed publications that might matter to examination, in writing, before the earlier of the notice of allowance or the later of (a) 6 months after the application’s publication or (b) the first examiner rejection of any claim. Those submissions must explain why each document is relevant, include any required fee, and state that the submitter followed these rules.

Patents — Source: USLM XML via OLRC

(a)Except as provided in subsection (b), applications for patents shall be kept in confidence by the Patent and Trademark Office and no information concerning the same given without authority of the applicant or owner unless necessary to carry out the provisions of an Act of Congress or in such special circumstances as may be determined by the Director.
(b)(1)(A)Subject to paragraph (2), each application for a patent shall be published, in accordance with procedures determined by the Director, promptly after the expiration of a period of 18 months from the earliest filing date for which a benefit is sought under this title. At the request of the applicant, an application may be published earlier than the end of such 18-month period.
(B)No information concerning published patent applications shall be made available to the public except as the Director determines.
(C)Notwithstanding any other provision of law, a determination by the Director to release or not to release information concerning a published patent application shall be final and nonreviewable.
(2)(A)An application shall not be published if that application is—
(i)no longer pending;
(ii)subject to a secrecy order under section 181;
(iii)a provisional application filed under section 111(b); or
(iv)an application for a design patent filed under chapter 16.
(B)(i)If an applicant makes a request upon filing, certifying that the invention disclosed in the application has not and will not be the subject of an application filed in another country, or under a multilateral international agreement, that requires publication of applications 18 months after filing, the application shall not be published as provided in paragraph (1).
(ii)An applicant may rescind a request made under clause (i) at any time.
(iii)An applicant who has made a request under clause (i) but who subsequently files, in a foreign country or under a multilateral international agreement specified in clause (i), an application directed to the invention disclosed in the application filed in the Patent and Trademark Office, shall notify the Director of such filing not later than 45 days after the date of the filing of such foreign or international application. A failure of the applicant to provide such notice within the prescribed period shall result in the application being regarded as abandoned.
(iv)If an applicant rescinds a request made under clause (i) or notifies the Director that an application was filed in a foreign country or under a multilateral international agreement specified in clause (i), the application shall be published in accordance with the provisions of paragraph (1) on or as soon as is practical after the date that is specified in clause (i).
(v)If an applicant has filed applications in one or more foreign countries, directly or through a multilateral international agreement, and such foreign filed applications corresponding to an application filed in the Patent and Trademark Office or the description of the invention in such foreign filed applications is less extensive than the application or description of the invention in the application filed in the Patent and Trademark Office, the applicant may submit a redacted copy of the application filed in the Patent and Trademark Office eliminating any part or description of the invention in such application that is not also contained in any of the corresponding applications filed in a foreign country. The Director may only publish the redacted copy of the application unless the redacted copy of the application is not received within 16 months after the earliest effective filing date for which a benefit is sought under this title. The provisions of section 154(d) shall not apply to a claim if the description of the invention published in the redacted application filed under this clause with respect to the claim does not enable a person skilled in the art to make and use the subject matter of the claim.
(c)The Director shall establish appropriate procedures to ensure that no protest or other form of pre-issuance opposition to the grant of a patent on an application may be initiated after publication of the application without the express written consent of the applicant.
(d)No application for patent shall be published under subsection (b)(1) if the publication or disclosure of such invention would be detrimental to the national security. The Director shall establish appropriate procedures to ensure that such applications are promptly identified and the secrecy of such inventions is maintained in accordance with chapter 17.
(e)(1)Any third party may submit for consideration and inclusion in the record of a patent application, any patent, published patent application, or other printed publication of potential relevance to the examination of the application, if such submission is made in writing before the earlier of—
(A)the date a notice of allowance under section 151 is given or mailed in the application for patent; or
(B)the later of—
(i)6 months after the date on which the application for patent is first published under section 122 by the Office, or
(ii)the date of the first rejection under section 132 of any claim by the examiner during the examination of the application for patent.
(2)Any submission under paragraph (1) shall—
(A)set forth a concise description of the asserted relevance of each submitted document;
(B)be accompanied by such fee as the Director may prescribe; and
(C)include a statement by the person making such submission affirming that the submission was made in compliance with this section.
