PatentsView

API

Free API for exploring US patent trends and innovation patterns

Overview

The PatentsView API offers RESTful access to detailed US patent data, including patents, inventors, assignees, citations, and classification metrics. Core endpoints like /patents, /inventors, and /assignees support filtered queries (e.g., grant year, technology class, assignee name). Responses are structured in JSON for easy parsing. Use cases include academic research on innovation trends, business intelligence to track competitor patent portfolios, policy analysis of tech ecosystems, and building visualizations of patent networks or geographic innovation hotspots.
