Screening candidates before anyone bills a serious hour. ClaimHit maps each claim limitation against the public record and shows the excerpt behind every line — including, deliberately, the limitations it could not evidence.
The claim is decomposed into individual elements — independent separated from dependent, inventive core from scaffolding — and each is judged on its own evidence.
Citations are validated against the passage they claim to come from. A plausible-sounding reference that does not contain the support is rejected, not shipped.
PARTIAL is never rounded up to FULL, and an undocumented limitation is reported NONE. Where a paywalled teardown exists, that is flagged rather than pretended away.
Have a teardown or an internal spec? Add it and its evidence folds into the chart — additively, never lowering what the public record already established.
Candidates come from several models, live web and neural search, forward citations, and the authoritative registries for the field — but breadth only widens the net. Each one is still checked against real, citable evidence, and anything that cannot be evidenced is dropped rather than shown with a caveat. See every source →
ClaimHit produces preliminary research, not legal advice. Infringement determinations require qualified counsel — the point is to get to that conversation with the evidence already assembled.
