Patent Review

What it solves

Chinese patent applications often contain unclear claim boundaries, broken dependency chains, weak specification support, and mismatched technical effects. Manual review is slow and can vary by reviewer. This skill structures pre-filing review into repeatable checks that surface blocking defects first and produce auditable notes.

How it works

• Input: Supports .docx, .pdf, .txt, and .md; .docx is converted to Markdown via scripts/docx_to_text.py, preserving paragraph order and tables where possible.
• Stage 1 — Claims: Checks independent claim features, dependent claim references, method/product/use/functional claims, multiple dependencies, reference signs, prohibited wording, and clarity.
• Stage 2 — Specification: Checks technical field, background, summary, embodiments, and comparative examples, testing whether the specification supports the claims.
• Stage 3 — Cross-validation: Validates consistency between claims and specification, technical effect closure, claim-chain consistency, and summarizes issues by ★★★, ★★, and ★.
• Output: Each stage produces a Markdown notice, then a .docx file via scripts/md_to_docx.py; incomplete or long inputs are handled by priority-based fallback with explicit notes.

Boundaries

The skill performs text-based legal and drafting checks, not prior-art search, experimental data validation, examiner discretion, or litigation strategy. Material issues such as inventive step, novelty, doctrine of equivalents, and disclaimer still require final judgment by patent counsel.
