TIPO

Verified Sep 2026

Taiwan's Intellectual Property Office (TIPO) publishes patent gazette, application, priority, annuity, and rights-transfer records through a REST API now hosted at cloud.tipo.gov.tw, after the old tiponet.tipo.gov.tw gazette pages were retired in favor of a unified Patent & Trademark Open Data portal. Every call needs a free verification token issued by TIPO and can return JSON or XML; without a valid token the API still answers with representative sample records rather than an outright error. A live request against the actual query endpoint came back with no CORS header at all, so browser-side cross-origin calls are blocked even though the separate spec-download endpoint does allow them.
