SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill generates a patent claim chart or a civil element chart that maps each element against the target with pin-cited evidence, then highlights what is missing so you can plan discovery or refine a motion strategy.

Core Features & Use Cases

  • Mode-based claim charting: Supports patent element-by-element mapping for infringement, invalidity, or review, and civil element mapping for causes of action and affirmative defenses.
  • Gap detection as the priority output: Produces a structured list of needs-evidence (patent) or gaps (civil) to guide the next attorney actions and discovery.
  • Evidence-first cells with pin cites: Requires verbatim, pin-cited evidence per cell and treats every row as a lead requiring attorney verification.
  • Output flexibility: Writes results in Markdown plus spreadsheet formats (CSV with sources companions and Excel/Sheets) and logs history under the active matter when enabled.

Quick Start

Ask for a chart by saying whether you want a patent claim chart or a civil element chart, then include the target (accused product/prior art/evidence corpus or pleading count) and the jurisdiction and posture so the Skill can map elements and return the gap list.

FAQPage Schema
How do I build a claim chart with pin-cited evidence for patent infringement analysis?

To build a patent claim chart, this tool maps each claim element against an accused product or prior art target, requiring verbatim pin-cited evidence per cell to support infringement or invalidity assertions.

What is the best way to map civil elements and find proof gaps for MSJ preparation?

Civil element charting maps each element of a cause of action or affirmative defense against a pleading or evidence corpus, surfacing explicit gaps to guide discovery and MSJ strategy.

How do I generate a needs-evidence list for patent invalidity or litigation review?

The charting process prioritizes gap detection by evaluating each mapped element and outputting a structured needs-evidence list that highlights missing proof and disputed states for attorney action.

Can I export claim chart results to a spreadsheet for litigation matter tracking?

Yes, the output supports Markdown plus spreadsheet formats including CSV with source companions and Excel or Sheets, while logging history under the active matter workspace when enabled.

Does claim charting work for both civil plausibility analysis and patent review audits?

Yes, the tool supports mode-based charting for both civil element mapping to analyze plausibility and discovery, and patent element mapping for infringement, invalidity, and review-audit postures.

What are the limitations of automated element mapping for legal evidence verification?

Every row is treated as a lead requiring attorney verification, with draft-verification guardrails ensuring the pin-cited evidence and disputed or needs-evidence states must be confirmed before use.
