Claude Patent Creator

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 takes your description (or even your source code), hunts for prior art, drafts claims and a specification, checks everything, and hands you a package a patent professional can review quickly — for US or European filing.

What this tool will and will not do — read this first

This tool is built for people who cannot afford a mistake, so it is honest to a fault. Know what you are getting:

• It will tell you "no." If the search finds your idea already exists, the tool's job is to show you the evidence and save you the filing fee — not to flatter you into spending money. A well-reasoned "this is not new, and here is why" is the tool working, not failing.
• It never says "verified" loosely. Every automated check reports what it ran and what it skipped. If a report looks clean, you can trust that the words mean exactly what they say.
• It does not file anything for you. You review, you decide, you file. The tool prepares; you commit.
• It is not a lawyer and does not give legal advice. What it produces is a well-prepared draft plus organized evidence — built so that a patent professional's review is fast and cheap instead of slow and expensive. For anything you intend to file, have a registered patent practitioner look at it. The point of this tool is to make that look-over affordable, not to skip it.
• Some judgments are human-only. Whether your invention is "non-obvious" and whether it is the kind of thing patent law protects at all are legal judgments no software makes reliably. The tool arms you for those conversations; it does not have them for you.
