An “Office action” is a written notification to the applicant of the examiner’s decision on patentability. The full-text of Public Office Actions is bundled as a JSON file in downloadable weekly zip files.


The United States Patent and Trademark Office (USPTO) Office Action Retrieval API provides access to the full-text information of Office actions issued by patent examiners to applicants during the patent examination process. The “Office action” is a written notification to the applicant of the examiner’s decision on patentability. It generally discloses the reasons for any rejections, objections, or requirements and includes relevant information or references that the applicant may find useful for responding to the examiner and deciding whether to continue prosecuting the application.  This api refreshes daily and contains publicly available Office Actions starting with 12 series applications.
