In a recent matter before the Gauteng North High Court (Bayerische Motoren Werke v Grandmark International) BMW took on a spare parts manufacturer, Grandmark International, for alleged infringement of its registered designs. The designs related to various parts of a motor vehicle, for example a bonnet, which BMW alleged were being infringed by Grandmark. However, the court found that a part such as a bonnet is a purely functional article, and as such cannot be filed as an aesthetic design. This judgment sparked debate from various corners, as it has a profound impact on original motor manufactures and replacement part manufactures alike.
