Patent Landscape

Prior art work is judged on methodology: what was searched, in which sources, with which queries, and when. Those are exactly the facts a CROWN receipt records. When agents run landscape sweeps through the Crux Daemon, every retrieval mints a signed, timestamped receipt naming the query and corpus, hash-chained so the search record cannot be embellished after the fact. If completeness is challenged during prosecution or litigation, the answer is a replay.

Landscape outputs, patent family clusters, density maps, and white-space candidates, inherit that provenance: each observation traces to the receipted retrievals behind it. Freedom-to-operate work benefits most, since FTO conclusions are precisely the ones that get relitigated years later against the question of what the searcher knew.

Budgeted retrieval keeps wide technology-area sweeps affordable enough to repeat, and repeatability is the point: a landscape rerun against the same queries produces a signed diff of what changed in the art. Confidential invention material stays local, because the daemon runs on your infrastructure, and exported search reports verify offline.
