The Free Claude Agent That Drafts Your Patent Application
A free, open-source patent kit for Claude Code, built by someone who filed his own patent with it: it checks over 100 million patents to see if your idea is new, drafts the application with drawings, and reviews it like an examiner
Getting a patent drafted usually means paying someone by the hour before you even know if your idea is new. This free kit puts Claude on it first: it searches existing patents for anything close to your invention, drafts the application from your plain-English description, and checks the draft the way an examiner would, so a professional's review is fast and cheap instead of slow and expensive.
Here's what it does, how to set it up, and the catch.
What it does for you
- Checks if your idea is new: a prior-art search across more than 100 million patents worldwide, with the closest matches and an honest verdict.
- Saves you the filing fee when the answer is no: if your idea already exists, it shows you the evidence instead of flattering you.
- Drafts the application: describe your invention and /create-patent walks you through claims, specification and abstract (typically about an hour).
- Makes the drawings: patent-style block diagrams and flowcharts from a description, no design software.
- Reviews it like an examiner: /full-review flags unclear wording, terms used before they're introduced, missing sections and an abstract that's too long.
- Answers rule questions in plain English with a citation from the examiner's rulebook (the MPEP), in about a second.
