Patent Connector: a Patent MCP Server and CLI
The most advanced MCP server for patents and trademarks, with the broadest coverage, plus a matching CLI for the terminal.
Official patent, trademark and design data, straight from the offices, for Claude, ChatGPT and your shell. One engine, two ways to use it, across six jurisdictions. No scraping, no aggregators, no intermediate database.
Choose your variant
Patent Connector for AI (MCP server)
Plug Claude, ChatGPT, local and company-internal chatbots, and any MCP-based agent straight into official IP data. Hosted or self-hosted. Reviewed and approved by OpenAI as a supported app, with one-click install from the ChatGPT app directory.
Patent Connector CLI (terminal)
Built agentic-AI-first. The same coverage from your terminal or inside your own agents. Run it locally in-process, against the hosted service, or on your own self-hosted server, with output as JSON, table or YAML.
What you can do
- Patents: keyword, field and classification search at the EPO, USPTO, DPMA and IP Australia, with filters for applicant, classification and date range; claims, full text, drawings, families and legal status, with full text across 30+ countries via EPO Open Patent Services; plus JPO and TIPO lookups, number conversion, summaries, prosecution timelines, patent term and side-by-side comparisons.
- Prosecution and prior art: ownership and continuity chains, register and prosecution events, file-wrapper documents and PDFs, USPTO office actions, rejections and petitions, EPO and JPO prior-art citations, and PTAB trials, appeals and interferences.
- Trademarks and designs: search EU and Australian trademarks and registered designs (EUIPO, IP Australia); status, documents and images for the US, EU, Japan, Australia and Taiwan; EUIPO sound, multimedia and 3D-model marks as playable links; and Nice/Locarno classification-term and owner search.
- Classifications and manuals, always on, no API keys: CPC, IPC, FI and JPO F-terms with full hierarchy and concordances; Nice and Locarno term discovery; examination manuals from the USPTO, EPO, EUIPO, WIPO, KIPO, JPO, DPMA and IP Australia; found by meaning, with built-in semantic search and no setup.

Why it is different
- Broadest coverage. Patents, trademarks and designs across six jurisdictions, all from official sources. One connector, not a drawer of half-finished integrations.
- Asian offices, rarely covered. Japan (JPO) and Taiwan (TIPO) patents, trademarks and designs, plus Korean (KIPO) examination guidelines, coverage most patent tools simply skip.
- First-hand and always current. Patent Connector queries the official office APIs directly. No scraping, no aggregator, no intermediate database, so the data is as current as the office itself.
- No intermediary, not even me. Run it self-hosted or standalone and nothing sits between your users and the patent office. Your credentials, your environment.
- Built for IP-grade privacy. Designed around the confidentiality demands of patent and trademark work, so sensitive searches stay yours.
- Yours to run. Hosted, self-hosted, or standalone in-process.
- Open and free, no paywall. Most patent tools hide behind a sales demo, charge from day one, or ship a stripped-down trial. The hosted MCP server and the CLI are open and free, without limits.
