An AI-powered patent creation and analysis system for Claude Code.
I built this because I needed to file a patent myself. I used AI to build the system, used the system to file the patent, and it worked. Now it's open source so anyone can use it. You do not need to be a lawyer or a programmer. If you can describe your idea in a chat window, you can use this.
In plain terms, this tool lets you:
- Ask patent-rule questions in plain English. "Do my claims have to be numbered?" "How long can the abstract be?" You get the actual rule, with a citation, in about a second. (Under the hood it searches the MPEP, the examiner's rulebook, plus the patent statutes and regulations.)
- Find out whether your idea is actually new. Search more than 100 million existing patents worldwide for anything close to your invention. This is called a prior art search, and it is the single most important step — it is how you learn whether a patent is even worth pursuing.
- Get your draft checked before a human ever bills you an hour. The tool reads your claims and application the way an examiner would and flags the mechanical problems: unclear wording, missing sections, an abstract that is too long. It also tells you which checks it did not run, so a clean report means what it says.
- Make the drawings. Patent-style diagrams and flowcharts from a description, no design software.
- Go from "here is my idea" to a reviewable draft application. A guided workflow

Questions
What is the Claude Patent Creator MCP server?
USPTO patent creation system with MCP server + Claude Code plugin. Hybrid RAG search over MPEP/USC/CFR, BigQuery access to 76M+ patents, automated 35 USC 112 compliance checks, prior art search, diagram generation. GPU-accelerated with skills and autonomous agents.
What tools does Claude Patent Creator expose?
9 in total: 9 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Claude Patent Creator safe to connect to an agent?
With care. The audit graded it B (89/100) and found 7 things worth knowing before you trust this server, listed below with the exact line each was found on.
What credentials does Claude Patent Creator need?
It reads ANTHROPIC_API_KEY, EPO_OPS_KEY, EPO_OPS_SECRET, GOOGLE_APPLICATION_CREDENTIALS, OPENAI_API_KEY, SERPAPI_API_KEY and USPTO_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How current is this page?
