Title 35 › Part PART II— - PATENTABILITY OF INVENTIONS AND GRANT OF PATENTS › Chapter CHAPTER 11— - APPLICATION FOR PATENT › § 122
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 An applicant can ask at filing that the application not be published by certifying they have not and will not file for the same invention in another country or under an international agreement that requires 18-month publication.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 If publishing an application would harm national security, it will not be published and will be handled under the secrecy rules in chapter 17.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.
