Give your chatbot direct access to patent databases

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

What you can do:

  • Retrieve full claim text for any patent number
  • Browse PTAB proceedings and decisions
  • Look up patent families and legal status
  • Search prior art by keyword or classification
  • Compare claims across related patents

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 info@patent.dev.

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.
