This Practice Note sets out a summary of the protection that can be obtained for geographical indications (GIs) and designations of origin, including appellations of origin, protected designations of origin (PDOs) and protected GIs (PGIs) in the UK (including the differences between the regimes for Great Britain and Northern Ireland). It considers how appellations of origin, PDOs and PGIs interact with trade mark law. It sets out details of the international framework for protection pursuant to the Paris Convention for the Protection of Industrial Property and the Agreement on Trade-Related Aspects of Intellectual Property Rights (the TRIPS Agreement) alongside relevant protections under UK law, including the UK GI scheme—put in place once the EU regime was no longer applicable in Great Britain—as well as the limited protection available under the Trade Marks Act 1994.
