This server resolves patent publication numbers to their canonical DOCDB (European Patent Office) identifiers. Specifically, you can:

• Look up patent records by providing a two-letter country code (e.g., US, EP, WO) and a publication number (without kind code) to retrieve canonical DOCDB records

• Normalize DOCDB IDs — returns the canonical DOCDB ID including the kind code suffix (e.g., US8000000B2), useful for normalizing patents cited in varying formats

• Get first inventor names (in caps) to verify matches against citations like "Greenberg et al."

• Get publication dates (in YYYYMMDD format) to cross-reference patents cited with year references

• Retrieve patent family IDs to identify related patent documents across jurisdictions

• Handle multiple document variants — if a publication number has both A1 and B2 versions, all matching records are returned so the correct one can be selected

• Receive structured error guidance via error codes (e.g., cc_does_not_exist, number_is_not_alnum) to help correct malformed inputs

Note: Leading zeros in the number are ignored automatically; strip kind codes, hyphens, spaces, and slashes before calling. An empty result means no match was found, not an error.

1. Click on "Install Server".

2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.

3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@docdb-mcp resolve US patent 8,000,000 to DOCDB"

That's it! The server will respond to your query, and you can continue using it as needed.

Here is a step-by-step guide with screenshots.
