Office Action Citations API (Version 2)

Data provided by  United States Patent and Trademark Office

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 examiners 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 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. Due to popular requests/demands, we have updated OA Citations API. Please see the JSON field mappings between OA Citations v1 and v2 as some fields have been updated in v2.
