ClaimHit / Methodology
How ClaimHit finds products
ClaimHit runs a multi-stage verification pipeline rather than rendering infringement judgments. Every patent goes through the same five stages, designed to surface real products while keeping an evidentiary standard.
Five stages, in order
Illustrative run on one patent
Numbers are illustrative. Every verified result links to the manufacturer page that confirmed it.
Parallel candidate discovery
Multiple independent models analyse a patent's inventive contribution at the same time, each proposing candidate products without knowledge of the others' findings. Agreement strengthens the signal; disagreement preserves breadth rather than eliminating candidates too early.
Web grounding
Two retrieval engines run live web searches, one matching on meaning, one on exact keywords. They target manufacturer pages, feature pages, use cases, comparisons and reviews to find real products the models may have missed.
Structural noise filtering
Conservative filtering removes obvious non-products, such as user-generated platforms and news sites, before the expensive stages. Ambiguous entries continue rather than being rejected early.
Category-fit check
A focused review decides whether each candidate belongs in the same category as the invention. It favours recall over precision, so borderline products move on to verification.
Manufacturer-page verification
Confirmation happens on the manufacturer's own domain: the page resolves, the vocabulary matches, the model is the right one. Only confirmed candidates become results, with their sources attached.
Two more ways in
Forward citations
Patents that cite the original point to companies working in adjacent areas. Candidates from the citation graph go through stages three to five like any other.
Registries, routed by field
Component distributors, regulatory databases, software directories and consumer marketplaces are queried according to the invention's field, so sourcing stays relevant instead of spraying every registry.
Leads with their evidence attached
Every result is a company and product that survived all five stages, shown with the sources that confirmed it. Results are preliminary research leads, not infringement determinations.
Asked about the method
ClaimHit results are for preliminary research only. They surface candidates that may infringe, not infringement findings.
