Open Horizon Ltd, the appellant, is the registered proprietor of several PACIFIC trade marks in class 34 covering tobacco and cigarette products, with registrations dating back to 2003. Carnilinx (Pty) Ltd, the respondent, used and sought to register various ATLANTIC trade marks (including ATLANTIC, ATLANTIC WAVE, ATLANTIC MENTHOL and others) also in class 34. Open Horizon applied to the Gauteng Division of the High Court for an interdict restraining Carnilinx from using the ATLANTIC marks, alleging trade mark infringement under s 34(1)(a) of the Trade Marks Act 194 of 1993 and, later by amendment, unlawful competition. The High Court dismissed the application. Open Horizon appealed to the Supreme Court of Appeal.
