Adds a comprehensive workflow for patent analysis with specific search strategies and outputs that are not available in standard tools.

What this skill does
Patent — Prior-Art + Landscape Intelligence Portability: Requires webfetch (Google Patents, Espacenet, USPTO), WebSearch (adjacent academic art), Node.js with docx package, and optionally Lens.org API key for citation-graph signals. Works in Claude Code CLI natively. In Claude.ai with web tools + Code Execution + BYOK Lens.org, the workflow is supported. Out of scope: trademark, copyright, trade-secret. These are flagged at intake. Use a different skill or qualified counsel. Legal disclaimer: This skill produces search signal, not legal advice. Verdicts are technical assessments. Always consult a patent attorney before filing or licensing decisions. Non-Generic Framing — The Differentiator This skill is prior-art + landscape intelligence. It refuses to be a bucket. Every invocation commits to one of five sub-use-cases via the grill-me intake before any search runs. The chosen sub-use-case dictates the entire search strategy, ranking heuristics, and DOCX emphasis. Sub-use-case Search strategy DOCX emphasis --- --- --- Novelty search Narrow + claims-text focused; pre-filing date irrelevant Closest art + claim-differentiation Freedom-to-operate Broad + active patents only; jurisdiction-filtered FTO flags + claim-by-claim risk Competitive landscape Breadth + filer tally + CPC trends Filer map + investment hotspots Acquisition diligence Specific assignee + portfolio scope + assignment chain Portfolio table + ownership verification Litigation prior-art Specific target patent + adjacent art before priority date Knock-out candidates ranked by relevance See references/subusecaserouting.md for the canon.
