What is the EPO Open Patent Services MCP Server?
Empower your AI agent to orchestrate your entire intellectual property research and patent auditing workflow with EPO Open Patent Services (OPS), the authoritative source for European and global patent data. By connecting the EPO OPS API to your agent, you transform complex patent searches into a natural conversation. Your agent can instantly retrieve bibliographic metadata, audit legal statuses, and identify applicants without you ever touching a patent portal. Whether you are conducting competitive intelligence or managing corporate IP constraints, your agent acts as a real-time patent consultant, ensuring your data is always verified and precise.
What you can do
- Patent Auditing — Search for thousands of published patents and retrieve high-resolution metadata, including titles, applicants, and publication dates.
- Legal Oversight — Audit the current legal status of any patent publication to understand the administrative reach of IP rights instantly.
- Bibliographic Discovery — Query detailed bibliographic data for specific Doc IDs to assist in deep-dive archival classification.
- Data Intelligence — Retrieve unique patent identifiers and applicant information to maintain strict organizational control over IP data.
- Operational Monitoring — Check API status to ensure your patent research workflow is always operational.
How it works
- Subscribe to this server
- Enter your EPO Consumer Key and Consumer Secret
- Start managing your IP intelligence through Claude, Cursor, or any MCP-compatible client
Who is this for?
- Patent Attorneys & Analysts — monitor patent filings and retrieve official metadata straight from your workflow.
- IP Researchers — verify legal statuses and audit applicant patterns without manual searching.
- R&D Leads — perform rapid audits of competitive patents and identify relevant technology markers through natural language.
