Overview

Researched from the vendor's own pages; every fact links to its source and the day we checked it.

The USPTO Open Data Portal (ODP) exposes REST APIs returning JSON for patent application data, continuity data, documents and patent term adjustments, with Swagger UI docs. An API key (X-API-KEY header) requires a USPTO.gov account with MFA and a linked ID.me account; unused keys are deleted after 90 days. PatentsView is migrating into ODP.

Rebuilt from the vendor's public docs, only what the pages show. Each operation links the page it came from; response shapes the docs don't spell out are left empty rather than guessed.
