About this skill

IMPORTANT — Working Directory: All scripts in this skill MUST be executed with the working directory set to the absolute path of the directory containing this SKILL.md file (the skill root directory). 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 Legal Status v1.0.0

Core Question

Is this patent still active, enforceable, expired, or affected by legal events?

Is this patent still valid?

Query patent legal status (valid/invalid/expired).

Clarify or Infer Before Querying

  • If patent ID/publication number is missing, ask for it first.
  • Clarify target country/authority if the patent has family members.
  • Do not assume a patent is enforceable just because a related family member exists.

Differs From / Not Applicable

  • Use patent-claim-analyzer for what the patent covers.
  • Use patent-family-explorer for country/family coverage.
  • Use patent-risk-checker for product-level risk screening.
  • Use this skill for expiration, enforceability, maintenance, and legal events.

Workflow

  1. Confirm patent/publication ID and authority/region.
  2. Fetch current legal status and event history.
  3. Identify active, expired, abandoned, pending, or uncertain status.
  4. Return enforceability caveats and next verification steps.

Usage

# Single patent
python3 scripts/patent_legal_status.py '{"patentNumber": "US11234567B2"}'

# Multiple patents
python3 scripts/patent_legal_status.py '{"patentNumber": "US11234567B2,CN115000000A,EP4000000A1"}'

# By patent ID
python3 scripts/patent_legal_status.py '{"patentId": "abc123,def456"}'

⚠️ 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.
