USPTO Office Action Rejection API

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.

This API allows for daily refresh and retrieval of rejection data from Office Actions mailed from June 1, 2018 to 180 days prior to the current date. It contains document level data including the type of actions taken on claims in the office action.

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