The patent-collateral dataset — point-in-time, survivorship-bias-free

The flagship deep dataset (USPTO patent-collateral history) — the anchor of the broader cross-register product; SBA / FMCSA / OSHA / EPA / FDA / Form 5500 / federal awards / SEC enrich it per company. See how it works.

Every event is dated as of the day it became a public record, evidence-backed and Ed25519-signed. Entities that later went bankrupt or delisted are not deliberately removed from the historical corpus — no survivorship bias. The accumulating point-in-time history is the asset; the live feed is the hook.

⚠ These are counts of recorded events, not of currently active security interests. Status of this security interest is not resolved on this page. A recorded security interest may since have been released; a recording is not a current state. A buyer evaluating this dataset should read every row as a security interest was recorded on this date, never as this company currently has a lien.

Data dictionary

field	meaning
`flag_code`	the red-flag type, e.g. IP_SECURITY_INTEREST_RECORDED
`entity_name / entity_slug`	canonical assignor (the flagged company) + its stable URL key
`ticker / cik`	SEC identity — attached ONLY where the dated crosswalk was valid as of this row's as_of (point-in-time, no look-ahead)
`severity / severity_score`	0–100 severity of the disclosed signal (not a market call)
`confidence`	detector confidence, kept separate from severity
`as_of`	the day it became a public USPTO record — the point-in-time anchor
`evidence_location`	where in the source: reel/frame, patent number
`evidence_hash`	SHA-256 binding the evidence text/location
`rule_version`	the versioned rule that fired
`source_url`	link back to the USPTO / Google Patents record
`release_status / state / state_as_of / coverage_end`	the resolved state of the recorded security interest — active, released, foreclosed or unknown — and ALWAYS the date it is resolved AS OF, which is the end of release coverage and not today. The three travel together: a state without its reference date is the misreading this field exists to prevent. release_status is unresolved where a record's state could not be computed. A row records that a security interest WAS RECORDED on as_of; on mature cohorts a majority have since been released
`signature`	Ed25519 over the signed field subset — verify against /v1/pubkey

Why it's defensible

Point-in-time strict — no look-ahead; every feature is computed as-of a timestamp.
Survivorship-bias-free — the bias hits distressed small-caps hardest, exactly this universe; a quant rejects a set that silently drops the failures.
Reproducible — each event replays its evidence path (filing → field → hash → parser + rule version). See a worked collateral trajectory end to end.
