WIPO Pearl API for terminology now available on WIPO Business Partner Platform

The Application Programming Interface (API) for the WIPO Pearl terminology database is now available through the WIPO Business Partner Portal, a new platform offering a simplified procedure for subscribing.

The API provides access to more than 285,000 terms from WIPO Pearl – meaning users can draw on validated, reliable scientific, technical and IP-related legal terminology across 29 subject fields in all 10 PCT publication languages to support tasks such as prior art search.

The API allows third-party software to connect automatically to WIPO Pearl and search terms without visiting the WIPO Pearl website, but does not provide all the features and functions available on the WIPO Pearl website.

For more information, visit the WIPO website.
