Patent Kit

AI-Native Patent Analysis Kit, designed for Claude Code.

[!IMPORTANT] > Disclaimer: This tool is provided for informational purposes only. The outputs do not constitute legal advice or professional patent opinions.

Overview

A complete toolkit that empowers AI agents to autonomously search, analyze, and evaluate patents with human-level precision.

This kit provides structured commands to automate:

• Concept Interview: Define product concept and identify competitors.
• Targeting: Create a target population from patent databases.
• Screening & Evaluation: Filter and analyze patents for relevance.
• Claim Analysis: Compare product features against patent elements.
• Prior Art Research: Search for prior art references for high-risk patents.
• Investigation Reporting: Track progress across all phases.

Install

Add this repository as a marketplace and install the plugin to your Claude Code environment:

# 1. Add this repository as a marketplace
claude plugin marketplace add sonesuke/patent-kit

# 2. Install the plugin (automatically loads required MCPs)
claude plugin install patent-kit@patent-kit-marketplace

Prerequisites

You must have the following CLI tools installed and accessible in your system PATH. When this plugin is loaded, it will automatically connect to these tools as built-in MCP servers.

• Google Patent CLI (google-patent-cli)
• arXiv CLI (arxiv-cli)
• sqlite3 — Required for database operations (screening, evaluating, etc.)

Quick Start

Navigate to your working directory and start Claude:

mkdir my-patent-project && cd my-patent-project
claude

Then run the skills in order:

/patent-kit:concept-interview
# Output: specification.md

Workflow

Phase 0: Concept Interview

Define product concept and identify competitors.

/patent-kit:concept-interview
# Output: specification.md

Phase 1: Targeting

Generate search queries and create a target population.

/patent-kit:targeting
# Output: targeting.md, keywords.md, csv/

Phase 2: Screening & Evaluation

Screen patents for relevance and evaluate claims.

/patent-kit:screening
# Output: patents.db (screening results)

/patent-kit:evaluating
# Output: patents.db (claims and elements)

Phase 3: Claim Analysis

Compare product features against patent elements.

/patent-kit:claim-analyzing
# Output: patents.db (similarity results)

Phase 4: Prior Art Research

Search for prior art references for patents with Moderate/Significant similarities.

/patent-kit:prior-art-researching
# Output: patents.db (prior art references)

Progress Report

Track progress across all phases at any time.

/patent-kit:investigation-reporting
# Output: PROGRESS.md (overall progress)
# Output: <patent_id>.md (specific patent report)
