Magister Legum - LLM / The rights relating to a trademark are said to be found in the fact that proprietors have acquired goodwill and a repute in their mark. Trademark law has always protected that aspect of what a trademark embodied, inter alia, to serve as a symbol of where a product originates from and guarantee quality by the setting the registered trademark proprietor’s goods apart from those of his competitor. The dilution of a trademark is one of the most challenging issues facing the sphere of trademark law in South Africa. Trademark proprietors have in the past relied successfully on primary and secondary or extended infringement. There has, however, been a dearth of cases on infringement by dilution thus far. The research in this study will primarily take the form of an evaluation of the development of the anti-dilution action and why there is dearth of successful cases in South Africa. Trademark proprietors are at risk of suffering financial loss if they are not able to protect their marks from dilution. The thesis will make recommendations whether the dilution provision contained in the Act need reform or whether the approach to the application of the anti-dilution provisions by our judiciary needs to change.
