The National Lotteries Board (NLB) was the registered proprietor of the trade mark 'LOTTO' in classes 36 (financial services) and 41 (lottery services). Uthingo Management (Pty) Ltd was appointed as the sole licensed operator of the National Lottery and used the mark in operating the Lotto game. On-line Lottery Services (Pty) Ltd conducted an online business under the trading name 'Lottofun', through which customers could order participation in the National Lottery. The NLB and Uthingo alleged that On-line’s activities infringed the LOTTO trade mark, constituted passing off, unlawful competition, and contravened the Lotteries Act. On-line opposed the claims and counter-applied for expungement of the LOTTO trade mark from the register, arguing that 'lotto' is a generic, descriptive term incapable of distinguishing, and that there had been non-use in respect of class 36.
