Give your chatbot direct access to patent databases

Instead of unreliable web searches, your AI pulls structured data directly from patent offices like USPTO, EPO and DPMA. Works with ChatGPT, Claude, LMStudio, AnythingLLM and other MCP-compatible tools.

What you can do:

• Search patents by keyword or classification
• Retrieve claims, abstracts, descriptions, and full documents
• Look up patent families, legal status, and prosecution history
• Browse PTAB proceedings and decisions
• Get patent summaries, timelines, and side-by-side comparisons
• Track ownership transfers and continuity chains

How to set it up:

1. Sign up below
2. Get free API keys from USPTO (data.uspto.gov) and EPO (developers.epo.org)
3. Enter your API keys here
4. Connect ChatGPT or Claude via Settings, then Connectors
5. Start asking

By signing up / using this tool you accept privacy policy.

If you need to keep queries confidential, Patent Connector can run on your own servers. Contact [email protected].

More patent offices: I am building API clients for additional patent offices. See the current status at patent.dev/patent-api-clients. If you need one that is not listed, let me know.
