USPTO Patents — questions

Answers built from our own checks of this server.

What can USPTO Patents do?

It exposes 3 tools, read directly from the server on our last check. Among them: uspto_assignee_portfolio, uspto_patent_search, uspto_read_patent. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is USPTO Patents working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 3 of 91 checks got a reply (3.3%), average response time 311 ms. The bar chart above shows every period we have measured.

The registry lists USPTO Patents as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect USPTO Patents?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does USPTO Patents need an API key?

No. USPTO Patents completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is USPTO Patents?

It answers our handshake in 311 ms on average, which is faster than 49% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is USPTO Patents open source?

We cannot say either way: written in TypeScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
