How it works

From patent to defensible chart in minutes.

Contist structures claims into elements, maps them against targets, and generates evidence-backed analysis — all connected to the underlying prosecution record.

1

Import claims

Claims are automatically parsed from patent documents. Independent and dependent claims are resolved into a structured hierarchy.

2

Structure elements

Each claim is decomposed into preamble, body, and wherein elements. Means-plus-function limitations are flagged automatically.

3

Add targets

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.

4

Generate chart

AI maps each element against each target, producing evidence-backed mappings. Review, refine, and export the final chart.

Claim dependency chains

Dependent claims are automatically resolved through their parent chain. The full hierarchy is visible in the matrix — no manual lookup needed.

Prosecution-grounded analysis

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.

Defensible and traceable

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.
