How do I find my EPO Credentials?

Register for an account at the [**EPO OPS developer portal**](https://developers.epo.org/), create an application, and you will receive your Consumer Key and Consumer Secret. Copy and paste them below.

Does it support legal status checks?

Yes. The `get_patent_legal_status` tool retrieves the current administrative and legal status metadata for specified patent publications.

What format is required for Doc IDs?

The API uses standard EPODOC format (e.g., EP1234567) for patent identifiers across all retrieval tools.

About 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.

Pydantic AI validates every EPO Open Patent Services tool response against typed schemas, catching data inconsistencies at build time. Connect 4 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.

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.

The EPO Open Patent Services MCP Server exposes 4 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

EPO Open Patent Services + Pydantic AI FAQ

Common questions about integrating EPO Open Patent Services MCP Server with Pydantic AI.

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your EPO Open Patent Services MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
