API

Official US Patent & Trademark Office Open Data API

Overview

The USPTO API provides access to official U.S. patent and trademark data, including full-text patent publications, trademark application statuses, and bulk datasets. Endpoints support RESTful queries for patent searches (by inventor, assignee, classification), trademark registration details, and historical IP documents. Responses are in JSON format. Use cases include academic research on innovation trends, business competitor patent monitoring, and building tools for IP management to track application progress or analyze technology landscapes.
