## Official patent offices block or gate programmatic access

- UK IPO: the patent search host is a dead redirect, the trademark-status host is a live Cloudflare CAPTCHA wall. [obj_01M45CWH0PWA140THQ8KYE5HE0]
- CNIPA's patent search system answers a plain GET with 412 Precondition Failed and an obfuscated WAF challenge, not a 403. [obj_01M45CWQH6XK8TVACNNN5HYXB6]
- J-PlatPat (Japan): every path, including the root, is redirected by PerimeterX to a dedicated reject_sorry.html bot page. [obj_01M45CWNX5NX53SKPFACKEWPTN]
- Lens.org: the website's own internal search API answers an opaque WAF 403, the documented api.lens.org host answers a clean 401 JSON refusal. [obj_01M45CWMAWX3X8G9BE0EJD3CB8]
- EPO Open Patent Services (OPS): anonymous search is throttled, not blocked outright — "AnonymousQuotaPerDay" 403, and the token endpoint wants Basic auth. [obj_01M45CW0QD1RS2H0C0MK95C871]
- WIPO PATENTSCOPE blocks only its search endpoints with a blanket 403 — the site root answers 200 to the same client. [obj_01M45CW8896KAMT63G2BF7418B]

## Undocumented, moved, or decommissioned endpoints

- Google Patents: robots.txt disallows the search surface, but the undocumented /xhr/query JSON API behind it answers fully, keyless, to a plain GET. [obj_01M45CWJRFRGD6T4D2AT8TK2VE]
- USPTO PatentsView is gone. [obj_01M3RAHFN64JP5TFAKGPZSPG1Q]
- USPTO's pre-ODP developer hosts (ibd-api, ped.uspto.gov) are gone: both 301 to the Open Data Portal's Angular shell. [obj_01M45CVZ0A2E4RYPK0RDRXCAJ0]
- EPO's "linked-data" SPARQL URL is actually a React SPA shell, not a raw SPARQL endpoint — and it exposes a seemingly unlimited anonymous weekly quota header. [obj_01M45CWS4DMQTQ7SAYNBTF21C4]
- CPC and IPC classification lookups (cooperativepatentclassification.org, WIPO IPCPUB) are JS browser apps with no discoverable static bulk-data path. [obj_01M45CWBMRSM2W48TMXXX0B8SF]
- FDA Orange Book — no API, a monthly zip at a non-stable FDA media-CMS URL. [obj_01M45J6RP7BHR3P463CV09CYQF]

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
