SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Litigators need element-by-element mappings of patent claims or civil causes of action against evidence, with every cell pin-cited and every evidentiary gap surfaced before a filing, MSJ, or trial. Manually building these charts is slow and prone to under-flagging missing proof. ## Core Features & Use Cases - Patent claim charts: Parse asserted claims into elements, flag construction disputes and means-plus-function terms, and map against accused products (infringement), prior art (invalidity), or an opposing party's chart (review), including dependent-claim rows and DOE candidacy rows. - Civil element charts: Map elements of a cause of action or affirmative defense against deposition testimony, declarations, and produced documents, with jurisdiction-specific formulations for Delaware, New York, and California surfaced proactively. - Gap detection: Produce a gap list (civil) or needs-evidence list (patent) as the priority output, framed by case phase from pre-filing plausibility through trial order of proof. - Use Case: A litigator asks "what are we missing to prove breach of contract" and receives an element chart with pin-cited evidence per element, strength ratings, and a discovery-priority gap list written to the matter's claim-charts folder. ## Quick Start Ask the assistant to build a claim chart for your asserted patent claims or a civil element chart for your pleaded cause of action, specifying the side, jurisdiction, and case phase.

Frequently Asked Questions about claim-chart

FAQPage Schema
How do I build a patent claim chart for infringement contentions?

Use patent mode with the infringement sub-mode, providing the patent number and asserted claims. The skill parses claims into numbered elements, flags disputed terms for construction, and maps each element against accused-product evidence with pin cites, producing dependent-claim rows and DOE candidacy rows.

How do I find what evidence is missing to prove a cause of action?

Use civil mode to map the elements of your pleaded claim against the evidence corpus. The skill produces a gap list of elements with thin or no evidence, framed by case phase as discovery priorities, MSJ targets, or trial proof assignments.

Does the claim chart support invalidity analysis against prior art?

Yes, the invalidity sub-mode maps claim elements against prior art references with column/line or paragraph pin cites. It distinguishes anticipation under section 102 from obviousness combinations under section 103 and flags section 101 and 112 issues.

Can I review an opposing party's claim chart or MSJ brief?

Yes, the review sub-mode audits an existing chart row by row. It checks whether each mapping is supported, whether pin cites are accurate, and outputs per-row verdicts of supported, weak, or unsupported plus the chart's vulnerabilities.

Does the skill handle jurisdiction-specific jury instructions?

Yes, the element template library provides baseline elements with citations, and the skill proactively surfaces Delaware, New York, and California formulations when those jurisdictions apply. The controlling pattern instruction or statute always overrides the baseline.

What are the limitations of a generated claim chart?

Every chart is a draft for attorney verification, not a filed contention or legal opinion. Each mapping is a lead the attorney must verify against the source, and gap detection is a starting point for discovery rather than a conclusion about the merits.
