The appellants, trustees of a trust owning several registered trade marks relating to shoe sole designs, sought an interdict in the High Court to prevent the respondents from allegedly infringing six trade marks registered in Class 25 (footwear). The respondents were competitors in the footwear market, including a former employee of the appellants, and manufactured shoes with similar sole designs. The respondents counter-applied for rectification of the trade mark register, arguing that the marks—consisting of shapes and configurations of shoe soles—were not registrable trade marks under the Trade Marks Act 62 of 1963. The High Court dismissed the infringement application and ordered the expungement of the marks. The appellants appealed to the Supreme Court of Appeal, primarily challenging the expungement and the finding of no infringement.
