Ground truth
Trained on what examiners cited.
Every patent examiner leaves a record: the prior art they cited against each claim. That is millions of labeled claim-to-art pairs, and it is the reason our numbers can be checked rather than asserted.
We structured a decade of it into training and evaluation data, then tuned two retrieval stages on it. The result walks from a claim to the nearest existing art the way the examiner would, across fields and across languages.
How you reach it
One retrieval layer, three ways in.
The product is the retrieval, not the interface. Your code calls the MCP server; your platform calls the API; you check the results by hand in the sandbox and the studio.
MCP server soon
Point your platform at one endpoint. It plans the retrieval, runs both neural stages, compares claim elements, and returns an answer traced to the source. One call.
Retrieval API soon
The same two-stage retrieval over REST. Send a claim or a disclosure, get a ranked, scored list with source passages. For teams building their own layer on top.
Sandbox & studio
The sandbox runs a live query and shows the call that produced it. The studio renders the same index as a space you can fly through. Check a result by hand in either before you wire the API into anything.
The call
A claim in. Ranked art, with receipts, out.
No query syntax. Pass the claim text; get back scored matches, examiner-citation lineage, and the exact passage each match rests on.
