SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Before filing a patent, inventors need to know whether their idea is novel and what existing patents or papers might block it. Manually searching Google Patents, Espacenet, and academic databases is slow and easy to do incompletely. ## Core Features & Use Cases - Multi-database patent search: Queries Google Patents and Espacenet using extracted keywords and predicted IPC/CPC classification codes, in both English and the target jurisdiction language. - Academic literature coverage: Searches Google Scholar, arXiv, and Semantic Scholar for non-patent prior art relevant to novelty and inventive step. - Structured risk analysis: Classifies each reference by overlap risk (HIGH/MEDIUM/LOW) and produces a preliminary freedom-to-operate assessment. - Use Case: Given an invention brief describing a new neural network compression method, the Skill extracts key technical features, searches patents and papers from the last 10 years, and writes a PRIOR_ART_REPORT.md with a landscape analysis and claim-scope recommendations. ## Quick Start Run a prior art search on my invention described in INVENTION_BRIEF.md and generate the patent/PRIOR_ART_REPORT.md report.

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

Provide an invention description or INVENTION_BRIEF.md file, and the Skill extracts core technical features, predicts IPC/CPC classes, then searches Google Patents, Espacenet, and academic databases. Results are compiled into a PRIOR_ART_REPORT.md with relevance and overlap risk ratings.

What patent databases does this prior art search cover?

It searches Google Patents and Espacenet for patents, plus Google Scholar, arXiv, and Semantic Scholar for non-patent literature. Searches run in English and, for CN filings, in Chinese as well.

Can academic papers count as prior art against a patent?

Yes. Academic papers published before the priority date are valid prior art for both novelty and inventive step. The Skill treats non-patent literature as equally important and includes it in the report with relevance ratings.

Does this replace a professional freedom-to-operate analysis?

No. The Skill provides only a preliminary freedom-to-operate assessment flagging patents with potentially overlapping claims. A formal FTO opinion from a patent attorney is still recommended before filing or commercialization.

How far back does the prior art search go?

The default search window covers the last 10 years, controlled by the SEARCH_YEARS constant. Expired patents are still included because they remain relevant for novelty even though they are in the public domain.
