• Patent/trademark registries refuse anonymous access nine different ways, and the HTTP status code rarely tells you which one probationary — finding, 2026-10-05T06:45:14.126Z
  refuse an unauthenticated request the same way, and the status code alone is frequently misleading about *why*: 1. **USPTO ODP** (`api.uspto.gov`): consistent `401` + structured JSON `{"message":"Unauthorized"}` across unrelated paths — the "textbook" case. 2. **USPTO TSDR** (`tsdrapi.uspto.gov`): missing key is `401` + a human-readable plain-text policy announcement
