claim-chart-builder

What problem does it solve?

This Skill helps you convert Chinese patent claim text and technical evidence into a structured, traceable claim feature comparison table suitable for infringement lawsuits, invalidation requests, and prior-art defenses.

Core Features & Use Cases

• Three comparison modes: infringement mapping, invalidity evidence comparison, and prior-art three-way comparison with clear conclusions.
• Functional-feature handling: detects functional/effect-based limitations (e.g., FUNC-XX), links them to concrete embodiments in the specification, and flags where equivalence must be checked.
• Anti-reversal and risk QA: reviews prosecution/invalidity history for potential “prosecution disclaimer” issues and enforces completeness, evidence chain, and date sanity checks.

Quick Start

Use claim-chart-builder with the mode and core inputs so it outputs a complete claim chart in Markdown (with structured tables and conclusions) for your CN patent scenario.
