Data version: English terms are taken from the EUIPO Harmonised Database and arranged in the 45 Nice classes; this site lists 73,491 entries. Chinese terms were fully retranslated on 1 October 2026 and are J&C reference translations. The reference number is this site's own number, not an EUIPO term ID. The English entries have not yet been checked one by one against the current EUIPO data; for filings, please rely on the official EUIPO source (TMclass).
