PatentsView vs TIPO

PatentsView, the NBER/USPTO-backed tool for mining trends across the US patent landscape, folded into the USPTO's unified Open Data Portal (ODP) in March 2026, retiring the standalone patentsview.org domain and its old keyless endpoint. Access now runs through ODP's api.uspto.gov gateway, which requires a free API key tied to a USPTO.gov account and returns JSON over HTTPS with CORS enabled. Every patentsview.org URL, including the one previously on file here, now 301-redirects to USPTO's own transition guide rather than serving data directly.

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.
