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, whether you're a developer exploring AI tooling or a patent professional looking to speed up your workflow.

In plain terms, this tool lets you:

• Search patent regulations instantly. Ask a question about MPEP, 35 USC, 37 CFR, EPC, or PCT rules and get the relevant sections in under a second, with citations.
• Find prior art across 100M+ patents. Search Google's BigQuery patent database by keywords, CPC/IPC codes, or full-text queries. Link related patents across jurisdictions with family search.
• Check your claims for compliance. Run your draft claims through automated analysis for USPTO (35 USC 112(b)) or EPO (Art. 84 EPC) and get specific feedback on definiteness, two-part form, and structure.
• Review your full application. Specification adequacy, formalities, required sections — checked against USPTO, EPO, or PCT standards.
• Search EP patents with full text. Get full claims and description text for European patents via the EPO OPS API (not available in BigQuery).
• Generate patent diagrams. Block diagrams, flowcharts, and system architectures in patent style, no design tools needed.
• Draft a complete patent application. A guided workflow that walks you through the whole process, from invention disclosure to filing-ready documents — for USPTO or EPO filing.

Quick Start

Pick the path that fits your setup. All three get you to the same place.

Option A: Claude Code Plugin (Easiest)

If you're already using Claude Code, this is the fastest way in:

# Add the marketplace and install
/plugin marketplace add RobThePCGuy/Claude-Patent-Creator
/plugin install claude-patent-creator-standalone@claude-patent-creator

# Run setup
/claude-patent-creator-standalone:setup-patent-system

Option B: One-Line Install

pip install git+https://github.com/RobThePCGuy/Claude-Patent-Creator.git && patent-creator setup

This handles everything automatically: installs dependencies, detects your GPU, downloads MPEP PDFs (~500MB), builds the search index, and registers the MCP server with Claude Code. Restart Claude Code when it finishes.

Option C: Manual Install

git clone https://github.com/RobThePCGuy/Claude-Patent-Creator.git
cd Claude-Patent-Creator

# Optional: use a virtual environment
python -m venv venv
source venv/bin/activate  # Linux/macOS
venv\Scripts\activate     # Windows

pip install -e .
patent-creator setup

Verify It Worked
