USPTO Office Action Citations API

v2 | Patents

This API allows for daily refresh and retrieval of citation data from Office Actions mailed from June 1, 2018 to 180 days prior to the current date. It uses information derived from citations referenced on the Form PTO-892, Form PTO-1449, and text of Office actions.


The United States Patent and Trademark Office (USPTO) Office Action Research Dataset for Patents contains detailed information derived from the 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.
