Office Action Weekly Zips API (Version 1)

Published by Open Data Portal Team | Department of Commerce | Metadata Last Checked: September 30, 2025 | Last Modified: 2025-08-28
The Office Action Retrieval API provides access to the full-text information of Office Actions (bundled as a JSON file in downloadable weekly zip files) 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 refreshes daily and contains publicly available Office Actions starting with 12 series applications. Please note that if you are not able to access the downloadable zips using the URL https://developer-hub, then please use the https://developer-hub.s3.amazonaws.com. For example, if the archiveFileName is bdr_oa_bulkdata_weekly_2020-11-22.zip, you can download the zip file using the URL https://developer-hub.s3.amazonaws.com/bdr-oa-bulkdata/weekly/bdr_oa_bulkdata_weekly_2020-11-22.zip. The base URL https://developer-hub.s3.amazonaws.com/bdr-oa-bulkdata/weekly/ is common for all the OA weekly zips.
