Always cd into this directory before running any command. Do NOT use relative paths or shell shortcuts like ~ in paths, as they may not be resolved by the execution environment.

Patent Risk Checker v1.1.0

Core Question

Does this product have patent/IP infringement risk in the target market?

Product Understanding Step

Before running this skill, if the user provides a product, image, ASIN, listing, product ID, or product idea, first identify:

• product type/category
• main use case
• key physical, design, or functional features
• target marketplace, country, or platform
• user's analysis goal

Use this product understanding to choose parameters, filters, competitors, regions, keywords, or analysis dimensions before executing the script.

Does this product have patent risks?

Patent infringement risk assessment via image search.

Clarify or Infer Before Querying

• If product image or product context is missing, ask for image URL, listing, or product details.
• Clarify target countries/regions before risk screening.
• Use patent-report-generator when the user asks for a complete clearance report.

Differs From / Not Applicable

• Use design-patent-analyzer for visual design-patent similarity only.
• Use patent-claim-analyzer for a known patent claim.
• Use patent-legal-status for expiration/validity.
• Use patent-report-generator for complete clearance reports.

Workflow

1. Understand product image/context and target regions.
2. Search for similar design/utility patent risks.
3. Assess similarity, active status, and litigation/legal relevance.
4. Return risk level, closest patents, and whether deeper claim/legal review is needed.

Usage

# Basic risk check by image
python3 scripts/patent_risk_checker.py '{"imageUrl": "https://example.com/product.jpg", "regions": "US,EU"}'

# With product info for utility patent check
python3 scripts/patent_risk_checker.py '{
  "imageUrl": "https://example.com/product.jpg",
  "productTitle": "Wireless Earbuds with Active Noise Cancellation",
  "productDescription": "TWS earbuds with ANC, 30hr battery...",
  "regions": "US"
}'

# Generate charts
python3 scripts/patent_risk_checker.py '{"imageUrl": "..."}' --chart /tmp/charts

⚠️ MANDATORY: Charts & Display Rules

1. Generate charts by default for full analytical reports — use --chart with an output directory unless the user asks for a quick text-only result or chart data is unavailable.
2. Send generated charts to the user — when charts are created, share all chart PNGs immediately.
3. All chart styling is driven by ecommerce_chart_helpers.py which reads from chart_style.json (derived from references/display-rules.md). Do NOT hardcode colors in scripts.

Risk Levels

Score	Level	Meaning	Recommendation
0-25	🟢 LOW	Minimal risk	Proceed with confidence
26-50	🟡 MEDIUM	Some concerns	Review flagged patents
51-75	🟠 HIGH	Significant risk	Legal consultation advised
76-100	🔴 CRITICAL	Major infringement risk	Do not proceed

Risk Scoring Algorithm

Risk Score = (
 Similarity × 50% +
 Legal_Status × 30% +
 Litigation × 20%
)

Component Breakdown

Factor	Weight	Logic
Similarity	50%	Highest similarity × 100
Legal Status	30%	% of active patents
Litigation	20%	100 if litigation history, else 0

Output Structure

The output will be a structured markdown report, following this format:

2. Before listing — Verify main product images
3. Before PPC — Don't advertise risky products
4. Periodically — New patents file constantly

What to Do with Results

Risk Level	Action
🟢 LOW	Document check, proceed

🟠 HIGH	Get legal opinion before proceeding
🔴 CRITICAL	Do not sell this product

Limitations

• Visual search works best with clear product images
• Utility search requires accurate product descriptions
• Results are advisory, not legal advice
• Some newer patents may not be indexed yet
