How it works

From claim to chart in four steps.

Each investigation covers one patent, from its claims to its final chart.

Step 1

Scope the claims

Import a patent by number or paste the claim text. Choose the claims in scope and set a publication cutoff.

ClaimCheckAIClaim selectionIllustrative example
Patent numberClaim text
Claim 1 · In scope1. A wireless charger, comprising:
  • 1.1a transmit coil driven at a resonant frequency;
  • 1.2a sensing circuit that measures a quality factor; and
  • 1.3a memory holding a stored reference value.
Publication cutoffBefore March 1, 2015
Step 2

Search every element

AI reads each claim in view of the specification, then searches patents, scholarly literature, and the public web for each element and scores what comes back.

Step 3

Read and rank

The closest documents are read in full and ranked on what they disclose. Elements without strong evidence are searched again.

What stays with you

ClaimCheckAI finds and maps evidence. The legal call is yours.

Publication dates are a discovery screen. Priority, exceptions, inherited claim limitations, and legal prior-art status need a reviewer’s analysis.
