Countries do not always move to a new Nice edition in exactly the same way, so the applicable edition should still be checked jurisdiction by jurisdiction. In the current Country Index 2026 poster, however, all listed countries and systems are shown as applying Nice (13th ed.), including the EU Trade Mark and International Trademark Registrations.
