The binding legal principles established are: (1) Under section 15 of the Trade Marks Act 194 of 1993, when determining whether a registered trade mark shall remain on the register, the court must assess whether matter contained in the mark is capable of distinguishing at the time of the rectification application, not at the date of original registration. (2) Section 15 applies both to determine whether a mark shall be entered on the register and whether it shall remain on the register, including in what form it should remain. (3) Matter that is merely the generic or descriptive name of a product type, rather than the name of a particular trader's product, is not capable of distinguishing within the meaning of section 9 and should be subject to a disclaimer. (4) A sole producer cannot render a generic product name capable of distinguishing merely through extensive sales and advertising under that name. (5) Use by third parties of matter contained within a composite mark, even with the proprietor's consent, does not constitute permitted use under section 38 unless the third parties use the trade mark as registered in its entirety. (6) A court has original discretion on appeal to decide whether to require a disclaimer and is not bound by the discretion exercised by the lower court or registrar.
