Australian Trademark Classification

AU42 Scientific and technological services

Data version: English terms are taken from the IP Australia Pick List of goods and services, arranged in the 45 Nice classes. On 9 October 2026 this site read IP Australia's official list pages and verified the entry counts class by class, and on 13 October 2026 the table was updated to match that official list: the site now lists 143,076 entries. Chinese and Spanish terms are reference translations. The reference number is this site's own number, not an IP Australia identifier. For filings, please rely on the official IP Australia source. Selected reference translations were further revised on 13 October 2026.
