SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you build or review patent claim charts and civil element charts so you can quickly see what each required element is supported by, and—most importantly—what gaps remain to prove (or defeat) a claim.

Core Features & Use Cases

  • Patent claim charts (infringement/invalidity/review): Converts asserted patent claims into element-by-element rows, flags claim-construction dependencies, and outputs a prioritized “needs-evidence” list.
  • Civil element charts: Maps a cause of action or affirmative defense’s elements against your evidence using a baseline element template, producing an element-to-proof chart plus a “gap list” for discovery and motion practice.
  • Gap-first outputs and file persistence: Writes charts to the active matter’s claim-charts directory when matter workspaces are enabled, and produces multiple export formats (Markdown, CSV plus sources, and spreadsheet formats) suitable for attorney review.
  • Safety/accuracy guardrails: Forces draft framing, disclosed-document restriction checks, and “every cell is a lead” verification posture to reduce the risk of overclaiming.

Quick Start

Use claim-chart in patent mode to chart asserted claims for infringement against an accused product, then return a prioritized list of missing evidence and a pin-cited element mapping ready for attorney verification.

FAQPage Schema
How do I map patent infringement claims to evidence and identify gaps?

To map patent infringement claims to evidence, the claim-chart skill converts asserted claims into element-by-element rows, flags construction dependencies, and outputs a prioritized needs-evidence list with pin-citations for each cell.

Can I use a claim chart for civil cause-of-action elements besides patents?

Yes, claim charting works for civil causes of action and affirmative defenses. The skill maps baseline element templates against your evidence to produce an element-to-proof chart and a gap list for discovery and motion practice.

What is the best way to review an existing claim chart for missing evidence?

Reviewing existing claim charts is done by applying gap-first detection and an every-cell-is-a-lead verification posture, which checks disclosed-document restrictions and flags unsupported elements to reduce overclaiming risk.

How do I generate a claim chart for invalidity analysis?

Generating an invalidity claim chart follows the same element-by-element mapping process as infringement charts, modeling construction-aware elements and returning a prioritized gap list of missing evidence needed to prove invalidity.

Does patent claim charting support export to CSV and spreadsheet formats?

Patent claim charting supports multiple export formats including Markdown, CSV with sources, and spreadsheet formats suitable for attorney review, and writes charts to the active matter's claim-charts directory when workspaces are enabled.

What limitations apply when mapping evidence to civil plausibility or MSJ elements?

Mapping civil plausibility, MSJ, or trial-prep elements requires forcing draft framing and disclosed-document restriction checks to prevent overclaiming, and every cell must be verified as a lead by an attorney before relying on the output.
