Use this API to retrieve patent assignment information from the USPTO assignment search database and generate XML files with the search results. An XML file with search results contains a list of found documents and their categorization. For API, please use Chrome or Safari browser.

The Enriched Citation API provides the Intellectual Property 5 (IP5 - EPO, JPO, KIPO, CNIPA, and USPTO) and the Public with greater insight into the patent evaluation process. It allows users to quickly view information about which references, or prior art, were cited in specific patent application Office Actions, including: bibliographic information of the reference, the claims that the prior art was cited against, and the relevant sections that the examiner relied upon. The API allows for daily refresh and retrieval of enrich citation data from Office Actions mailed from October 1, 2017 to 30 days prior to the current date.

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.

USPTO Patent Data – Overview (≈175 words) The USPTO Patent Data suite is a family of openly‑available research datasets produced by the United States Patent and Trademark Office’s Office of the Chief Economist (OCE). It aggregates all bibliographic, legal‑status, assignment, and examination records for U.S. utility patents (and related applications) spanning more than five decades—roughly 1970 through the present. The core files include: * PatentsView – a flexible API‑driven catalogue that lets users query, filter and bulk‑download 40 years of grant, citation, examiner, inventor, assignee, and classification information. * Patent Assignment Dataset – ~6 million transaction records (1970‑2014) linking patents to owners, useful for studying technology ownership and collateralisation. * Historical Patent Data Files – NBER‑classified micro‑level data on applications, grants and in‑force patents, enabling sector‑level innovation analysis. * Office‑Action (PatEx) and Examination Datasets – detailed examiner‑applicant interaction logs for research on the patent prosecution process. The overarching purpose is to enable economists, scholars, and policy analysts to investigate the economics of invention, diffusion, and IP markets. Typical use cases include measuring R&D productivity, mapping technology spillovers, evaluating patent‑policy reforms, and building machine‑learning models of novelty or litigation risk. Unique aspects are the breadth of coverage (full U.S. patent universe), the integration of NBER technology classifications, and an openly‑documented API that supports both ad‑hoc queries and massive bulk extracts.

The Open Data Portal (ODP) is our new hub for open data, built on the idea of finding several datasets in one platform so anyone can easily search and extract the data they need. The ODP is a unified platform that offers public patent data in one place. Enhanced APIs and robust documentation help improve the entire data experience. Customer demand for our data has grown rapidly since the launch of the original Open Data Portal initiative in 2015 – from 50 users to millions. The new Open Data Portal is the next step in the USPTO journey to amplify the public value, accessibility, and efficiency of patent data sharing. ODP will fold several data dissemination services into one central website that empowers you to rapidly discover and easily extract USPTO data however you want. Improved Patent Examination Data System (PEDS) capabilities, Bulk Data Storage System (BDSS), and Developer Hub features and datasets will be included in this tool.

USPTO Patent Trial and Appeal Board (PTAB) API Data contains data from the PTAB E2E (end-to-end) system making public America Invents Action (AIA) Trials information and documents available.

The Cancer Moonshot Patent Data Set API allows the public to discover and search USPTO Cancer Moonshot Patent Data.

USPTO Patent Examiner Data System (PEDS) API Data contains data from the examination process of USPTO patent applications. PEDS contains the bibliographic, published document and patent term extension data tabs in Public PAIR from 1981 to present. There is also some data dating back to 1935.

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.

Context

Patent Examination Data System gives users access to multiple records of USPTO patent application or patent filing status at no cost. PEDS is updated daily and mirrors the data available in the Patent Application Location and Monitoring system (PALM). PEDS provides access to public applications including: published patent applications and patents. PCT applications that have not been published by WIPO. Any applications that have not been released by the USPTO will not be available in PEDS.

Complete USPTO prosecution feed: original IFW PDFs, time-stamped events, and normalized office-action data, refreshed continuously. Ideal for file-history audits, examiner benchmarking, and AI analytics via API or bulk delivery.

Get access to transformed raw USPTO prosecution artefacts into a single, analyst-ready stream that shows exactly how every U.S. patent application travelled from first filing to final disposition. The feed combines three tightly linked layers: 1) the original, OCR-searchable Image File Wrapper PDFs for every document the USPTO processed; 2) a continuously updated transaction log that mirrors PAIR events in chronological order; 3) richly parsed Office-action analytics that expose the type, statutory ground (§ 102 novelty, § 103 obviousness, § 112 indefiniteness, etc.), date and outcome of each rejection, amendment or RCE.

Each PDF is captured with its key metadata: mail-room date, document code, description and page count; so you can audit file history without hunting through PAIR screenshots.

2022 Manual Behind the scenes, a nine-level prioritisation crawler polls the USPTO around the clock; new IFW documents for open applications are ingested as soon as they appear, and structured data are extracted within seconds of OCR completion.

The same engine builds the transaction log and refreshes rejection statistics, ensuring that examiner actions, applicant responses and PTA-relevant delays are available in near real-time.

Whether you need to validate claim scope before enforcement, benchmark examiner behaviour to fine-tune prosecution strategy, train an AI model on structured rejection data, or surface high-risk assets during due-diligence, USPTO File Wrapper & Office Action Data delivers a complete, time-stamped view that turns complex prosecution histories into actionable intelligence.

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 retrieval of citation data from 4.4 million Office actions mailed during the 2008 to mid-2017 period from USPTO examiners to the applicants of 2.2 million unique patent applications. It uses information derived from citations referenced on the Form PTO-892, Form PTO-1449, and text of Office Actions.
