What is the USPTO API MCP Server?
Empower your AI agent to orchestrate your entire intellectual property research workflow with USPTO API, the official source for United States patent and trademark data. By connecting the USPTO Open Data API to your agent, you transform complex legal lookups into a natural conversation. Your agent can instantly search for active patents, audit trademark registrations, and retrieve detailed abstract metadata without you ever touching a government portal. Whether you are conducting prior art research or monitoring brand protection, your agent acts as a real-time IP consultant, ensuring your data is always grounded in official, government-verified records.
What you can do
- Patent Auditing — Search for thousands of United States patents by keyword and retrieve detailed metadata, including abstracts and filing dates.
- Trademark Oversight — Audit active and pending trademark registrations to maintain a clear view of brand protection trends.
- IP Discovery — Retrieve full details for specific patent numbers or trademark serial numbers to assist in legal research.
- Classification Intelligence — List patent classification codes to understand the technological hierarchy of innovations instantly.
- Operational Monitoring — Check API status to ensure your IP research workflow is always operational.
