Claim Charts That Hold Up in Litigation and Licensing
Litigation-grade claim charting services for patent owners, law firms, and licensing teams, with every element verified by a qualified patent professional.
A patent claim chart is a structured document that maps each element of a patent claim to specific evidence: product features, technical documentation, standards clauses, or source code. It is the foundation of infringement analysis, licensing negotiation, and pre-litigation investigation, turning legal claim language into provable technical facts.
What a litigation-grade claim chart includes
Every chart is built element by element and delivered ready for counsel review, licensing discussions, or filing.
Element-by-element mapping
Each limitation of every asserted claim is mapped to specific, cited evidence. Never summarized, never assumed.
Verifiable evidence citations
Product documentation, technical specifications, standards documents, source code, and marketing material. Every mapping points to a source you can check.
Claim construction notes
Key terms are flagged with construction considerations, so your counsel sees disputes coming before the other side raises them.
Accused product analysis
Deep technical review of the accused product or standard implementation, incorporating reverse-engineering inputs where available.
Litigation-ready formatting
Charts structured for Rule 11 pre-filing investigation, district court, ITC, and licensing use, organized the way trial counsel actually works.
Portfolio-scale charting
Consistent methodology across patent families, jurisdictions, and continuations when the engagement spans more than one asset.
How we verify every deliverable
AI-assisted research, verified line by line by qualified patent professionals on every engagement, not just the big ones.
AI-assisted research sweep
Our tooling parses product documentation, standards libraries, and technical literature at machine scale, surfacing candidate evidence a manual pass would miss.
Human verification, element by element
A qualified patent professional checks every mapping against the primary source, confirms the citation, and rewrites anything the AI got wrong.
Expert review before delivery
The finished chart is reviewed for completeness, accuracy, and litigation-readiness, the same standard our 1200+ delivered charts are held to.
The Zero-Hallucination Guarantee
Every claim chart we deliver is backed by our Zero-Hallucination Guarantee: each mapping cites a real, verifiable source, and nothing is fabricated or assumed. If an element cannot be mapped to genuine evidence, the chart says so, because a chart that overstates your case is worse than no chart at all.
Turnaround and pricing
Our AI-assisted workflow compresses the research phase dramatically. We deliver claim charts up to 10× faster than traditional research firms, in days rather than weeks. Standard charts typically ship within 5 to 7 business days, with 48 to 72 hour turnaround available for rush matters.
Pricing is accessible and competitive: fixed-fee project pricing or retainer arrangements, with volume discounts for portfolio-scale work. You pay for verified technical work, not layers of account management. Contact us for a scoped quote on your matter.

Frequently asked questions
What is a patent claim chart?
A patent claim chart is a document that breaks a patent claim into its individual elements and maps each one to corresponding evidence, such as a product feature, a standard's technical clause, or prior art. Claim charts are the standard tool for infringement analysis, licensing negotiation, and pre-litigation investigation.
What is the difference between a claim chart and an evidence of use chart?
The two overlap heavily. A claim chart is the general deliverable: claim elements mapped to any form of evidence. An evidence of use (EoU) chart is a claim chart aimed specifically at products in the market, built to prove the invention is actually being practiced. Every EoU chart is a claim chart; not every claim chart is an EoU chart.
What is a Rule 11 claim chart?
A Rule 11 claim chart is prepared before filing an infringement suit to satisfy the pre-filing investigation duty under Federal Rule of Civil Procedure 11. It documents a good-faith, element-by-element basis for alleging infringement. A weak chart at this stage can undermine a case before it begins, which is why courts and counsel expect genuine technical rigor here.
How much does a claim chart cost?
Cost depends on claim count, technology complexity, and how many products are charted. We offer fixed-fee project pricing and retainer arrangements at accessible, competitive rates, typically well below traditional research firms because our AI-assisted workflow removes most of the manual research hours. Contact us for a scoped quote.
How long does a claim chart take?
Standard claim charts are typically delivered within 5 to 7 business days, and rush matters can be turned around in 48 to 72 hours. AI-assisted research verified by patent professionals makes us up to 10× faster than traditional firms without trading away accuracy.
Why not just use an AI claim chart generator?
Generators are fast, but they hallucinate: elements get mapped to evidence that does not exist or does not say what the chart claims it says. Every LitigateIQ chart is AI-assisted but verified element by element by a patent professional, which is why we can stand behind a Zero-Hallucination Guarantee and a generator cannot.
