What problem does it solve?

This Skill helps legal teams produce precise, mapped claim charts for patent infringement, validity, or civil action, ensuring every cell is pin-cited and accompanied by a gap or evidence list.

Core Features & Use Cases

  • Element-by-element mapping of asserted claims to an accused product or prior art, with per-cell pin citations.
  • Support for patent-mode (infringement / invalidity / review) and civil-mode element charts, including dependent claims and construction notes.
  • Output in Markdown, CSV, and Excel, plus a matter-aware history and file paths for organization and audit trails.
  • Real-world use: craft IPR/FDI contentions, discovery planning, or pleading prep with a structured evidentiary chart.

Quick Start

Ask me to generate a patent or civil claim chart by specifying mode (--patent or --civil), the side (plaintiff/defendant), jurisdiction, phase, and the pleadings or claims to chart.

FAQPage Schema
How do I generate a patent infringement claim chart with element mapping and pin cites?

You can generate a patent claim chart by specifying patent mode, side, jurisdiction, phase, and the asserted claims. The tool parses claim elements and maps them to an accused product with per-cell pin citations and gap lists.

What is a patent claim chart and when do I need element mapping for invalidity analysis?

Element mapping in a claim chart systematically links individual claim limitations to prior art or accused products. You need this for invalidity or infringement analysis to ensure every assertion is pin-cited and accompanied by an evidentiary gap list.

Can I create civil claim charts for plaintiff and defense pleadings?

Yes, civil claim charts are supported for both plaintiff and defense sides. By specifying civil mode and providing the pleadings, the tool parses claims into a structured, pin-cited chart to support civil action analysis and discovery planning.

Does this tool export claim charts to Excel and CSV formats?

Yes, the tool exports structured element mappings to Excel, CSV, and Markdown formats. These outputs include gap reports and matter-aware file paths to support organization and audit trails for legal teams.

What's the best way to prepare IPR contentions and discovery planning with a claim chart?

The best way to prepare IPR contentions is to use patent mode with invalidity review to map asserted claims to pertinent references. This produces a structured chart with gap reports and evidentiary citations for discovery planning.

What limitations exist when mapping dependent claims and construction notes in a claim chart?

Mapping dependent claims and construction notes requires asserted claims, pertinent references, and access to element templates. Without these specific inputs, the tool cannot produce the structured evidentiary chart or gap reports.
