Cyan Eclipse Patent Witness — Cyan Eclipse Bazaar

Certification scope

PARTIAL(local, FIXTURE scope) — Eclipse Bazaar Test Bench 2026-10-26, card eclipse-patent-witness-mcp-2026-10-26.json: certification WITHHELD on three MED defects (PW-D1, PW-D2, PW-D4); this product is NOT certified. The card's scope language is binding: scope caps at local, FIXTURE scope — every seal is FIXTURE_SIGNED under fixture keys over fixture extracts; the mechanism (sealed legal-status event ledger, claims divergence, assignment-chain witness, source-drift witness) was measured certified-grade and every derivation was independently recomputed byte-identical, but no CERTIFIED verdict exists for this product. Live ODP ingest is MEASURED BLOCKED (bench re-verified HTTP 401 without an operator ODP key) and no live seal exists.

What it does

Legal-status event ledger per subject — every event pinned to the hash of the source record that asserts it, inside a named sealed snapshot
Claims divergence receipts — the claim set as published vs the claim set as granted, diffed mechanically claim by claim
Assignment-chain witness — recorded conveyances sealed as a sequence with its gaps named as gaps
Source-drift witness — the upstream source surface is fingerprinted per snapshot and its drift is sealed as product output
Offline recompute of every artefact from the named snapshot package with the shipped standalone verifier (verifier.py)

Problems it addresses

I need the USPTO record of a patent as a sealed sequence of states I can recompute offline — not a live status lookup I have to trust
I need to prove how a patent's claim text diverged between publication and grant, claim by claim
I need the recorded assignment chain for a patent with its gaps named as gaps

Not tested

Certification — withheld pending a fix round on PW-D1/PW-D2/PW-D4 (PW-D3 as rider) plus a scoped re-bench
Live ODP ingest and any live seal — measured blocked without an operator ODP key (HTTP 401)
Patent search, full-text retrieval, status lookup, fee/deadline calculators, monitoring — these verbs do not exist on any surface by construction

Evaluation-intake listing

This listing records the tool's place in the Bazaar's evaluation and monitoring pipeline, with the evidence gathered so far printed above — verdict, scope, and not-tested items included. It is not sold on this site, and its presence in the catalog is not a claim beyond that evidence. The service behind every verdict is the bench: what a bench run buys →
