Registered patent practitioners are individuals who have passed the USPTO's registration exam and met the qualifications to represent patent applicants before the USPTO. Trademark practitioners are attorneys who are active members in good standing of the bar of the highest court of any State. NOTE: Because Trademark attorneys need not apply for registration to practice trademark law before the USPTO, the USPTO does not maintain a roster of trademark attorneys. The names of attorneys who specialize in trademark law may be found online, or by contacting a local bar association.

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 Open Data Portal (ODP) API allows you to access USPTO data at no cost ? with several ways to do it. The ODP API uses HTTP, GET, and POST requests to return responses in JSON format. ODP also provides REST APIs, which provide rich search capabilities and allow users to retrieve patent application data, continuity data, documents, patent term adjustment data, and much more. You must get an API Key to use the ODP API. Note: The data products on our website allow users to download data without the need for an API key. Using ODP APIs will require an API key.
