Claim Charting
Whether you're asserting infringement or challenging validity, every claim element maps to source evidence. Contist generates structured, defensible claim charts that stand up to scrutiny.
Get early accessHow it works
Contist structures claims into elements, maps them against targets, and generates evidence-backed analysis — all connected to the underlying prosecution record.
Claims are automatically parsed from patent documents. Independent and dependent claims are resolved into a structured hierarchy.
Each claim is decomposed into preamble, body, and wherein elements. Means-plus-function limitations are flagged automatically.
Define accused products for infringement, prior art references for invalidity, or other comparison targets. Each target gets its own column in the claim chart matrix.
AI maps each element against each target, producing evidence-backed mappings. Review, refine, and export the final chart.
Capabilities
A structured matrix of claims, elements, and targets. Each cell contains an AI-generated mapping with evidence, confidence rating, and source citations. Click any cell to review and refine.
Dependent claims are automatically resolved through their parent chain. The full hierarchy is visible in the matrix — no manual lookup needed.
Every claim element is linked to its prosecution history. See which amendments narrowed the claim, which arguments distinguish prior art, and how the claim evolved from filing to grant.
Every mapping traces back to source evidence. Every claim traces back to prosecution events. Whether for infringement or invalidity, reproducible outputs that can be reviewed, refined, and relied upon.
