SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires docx, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Patent searches are easy to do badly: vague queries, missed adjacent art, duplicated patent families, and confused filing dates lead to false novelty conclusions or missed infringement risk. This Skill enforces a disciplined, sub-use-case-specific search workflow with claim-text extraction, CPC class follow-up, family deduplication, and a full audit log.

Core Features & Use Cases

  • Five Committed Search Strategies: Forces intake commitment to one of novelty search, freedom-to-operate, competitive landscape, acquisition diligence, or litigation prior-art before any query runs, each with its own query plan, ranking heuristic, and verdict scale.
  • Multi-Source Search with Audit Discipline: Sequentially queries Google Patents, Espacenet, USPTO, and optionally Lens.org (BYOK) at 1 query/second, tracking searches sent, patents received, and patents cited.
  • Structured DOCX Dossier: Generates an 8-section Word report with verdict, ranked closest art with claim-1 text, landscape tables, FTO flags, geographic coverage, strategy recommendations, and audit log.
  • Use Case: Ask for a freedom-to-operate analysis for a new medical device in the US and EP; the Skill filters to active patents in those jurisdictions, extracts claims, flags infringement risk per patent, and delivers a DOCX with design-around recommendations.

Quick Start

Run a novelty prior-art search for my invention that uses federated learning to train models across hospitals without sharing patient data, and produce the DOCX report.

Frequently Asked Questions about patent

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run a patent prior-art search before filing?▼

Describe your invention in 2-3 sentences and commit to the novelty sub-use-case at intake. The Skill runs narrow and broad keyword queries on Google Patents and Espacenet, adds a CPC class-restricted follow-up, extracts claim 1 from top hits, and delivers a DOCX with a NOVEL, POTENTIALLY NOVEL, or NOT NOVEL verdict.

How to check freedom to operate before launching a product?▼

Choose the FTO sub-use-case and specify your sales jurisdictions. The Skill filters to active patents only in those jurisdictions, extracts independent and dependent claims, and flags infringement risk per patent as HIGH, MEDIUM, or LOW with design-around hints in the DOCX.

Does the patent search work without a Lens.org API key?▼

Yes. Google Patents, Espacenet, and USPTO require no authentication and cover the core search. Without a Lens.org key, the citation graph section is skipped and the DOCX notes that manual citation review is recommended.

Why does patent keyword search miss relevant prior art?▼

Patents often use different vocabulary for the same concept, especially across eras and fields. The Skill corrects this by extracting CPC classes from the top initial hits and running a class-restricted follow-up query, which consistently surfaces art that keyword-only search misses.

Can this skill handle trademark or copyright questions?▼

No. Trademark, copyright, and trade-secret questions are explicitly out of scope and flagged at intake. The Skill covers only patent searching and analysis, and its output is technical search signal, not legal advice.

What happens when the same invention is filed in multiple countries?▼

The family_resolver.py script groups patents by family ID or priority number so the same invention filed in the US, EP, and JP counts as one family. The DOCX surfaces one representative member plus all family jurisdictions to avoid inflated hit counts.
