Find the prior art that holds up.
ClaimCheckAI tests every claim element against patents and scholarly literature, then builds claim charts with quotations checked against the source.

Finding a similar document is the easy part. An invalidity position needs evidence for each limitation, quoted from the source, that survives review by the other side.
Verified quotations
A quotation is verified only when it matches the source. Anything else is marked unverified.
Read in full
Ranked references are read from start to finish, not judged from a snippet.
Gaps in plain view
The heatmap shows which elements lack strong evidence, so you know where a position is thin.
Your judgment
Priority, exceptions, and prior-art status stay with the reviewer.
From claim to chart in four steps
AI does the reading. You keep the judgment, from the claims in scope to every row of the chart.
- 1
Scope the claims
Import a patent by number or paste the claim text. Choose the claims in scope and set a publication cutoff.
- 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.
- 3
Read and rank
The closest documents are read in full and ranked on what they disclose. Elements without strong evidence are searched again.
- 4
Chart and export
Each limitation is mapped to quoted evidence. Accept or change every row, then export to Word, Excel, CSV, or JSON.

Private to your account, and on the record.
Invalidity work is often confidential. Here is who can see it, what is kept, and what leaves.
Read the Privacy PolicyPrivate to your account
Only the account that created an investigation can open it. To any other account, it doesn’t exist.
Approved accounts only
Anyone can read the patent library. Investigations need an approved account.
Every step on the record
Each search keeps the queries it ran, every score with its explanation, and the AI’s reasoning.
Clear about what leaves
To do the work, search terms go to search services, and claims and document text go to AI providers.
