The closest art, scored and explained.
The closest prior art, each with a score and the reasoning behind it.
- A reason for every scoreEach score comes with the AI’s explanation, so you can check the ranking instead of trusting it.
- Patents and literature togetherPatents and scholarly literature are ranked side by side, on what they disclose.
- Dated against your cutoffEach reference’s publication date is compared with the cutoff you set.
- 1Reference CCompares a measured coil value with a stored reference.84
- 2Reference ADetects metal near a charging coil.81
- 3Reference BSurveys resonance-based sensing.72
Every element, against every reference.
Which elements each reference covers, and where the gaps are.
- Strength at a glanceEach cell shows how strongly a reference discloses an element: strong, partial, or weak.
- Gaps searched againElements without strong evidence get another round of searching, and any still thin stand out in the grid.
- Patents and papers in one viewPatent and non-patent references share the same grid.

Built for the moments that need proof
Wherever a patent’s validity decides what happens next, the question is the same: what does the art already show?
Litigation defense
Answer an assertion with evidence for each element of the asserted claims.
IPR and PGR petitions
Gather the patents and printed publications a petition rests on, charted element by element.
Licensing negotiations
Test how well a patent holds up before you agree to pay for it.
Due diligence
Gauge the strength of the patents in a deal while there is still time to act.
Portfolio review
Find out which of your own patents face close prior art.
Pre-filing checks
Paste draft claims and see what is already published before you file.
Common questions
Does ClaimCheckAI decide what counts as prior art?
No. Publication dates are a discovery screen. Priority, exceptions, inherited claim limitations, and legal prior-art status need a reviewer’s analysis.
Where do the quotations come from?
From the source documents. A quotation is verified only when it matches the document text, and a search snippet never counts as verified disclosure.
Can I change what the AI produces?
Yes. You can edit the limitations before a search and accept or change every chart row before export.
What does a search cover?
Patents from 107 offices, scholarly literature, and the public web. The coverage page has the detail for each office.
Where does my research go?
Investigations are limited to approved accounts. To do the work, search terms go to search services, and claims and document text go to AI providers. The Privacy Policy has the detail.
Who can use ClaimCheckAI?
The patent library is open to everyone. Investigations need an approved account, which you can request here.
