Willis JA in a separate concurring judgment expressed concern about the 'copycat' nature of Truworths' intention to use the PRIMARK mark, noting that while imitation may be the sincerest form of flattery, a court sanctioning such endeavour may be disconcerting. However, he acknowledged that under The Gap precedent, the principle of territoriality prevails over policy considerations of morality in the absence of 'something more'. Willis JA observed that territorial isolation is vanishing due to mass air travel, television, internet and social media, and that if the principle of territoriality is to be revisited in light of changing social conditions, this requires internationally concerted political effort beyond the province of the courts. The main judgment also noted (without deciding) that Truworths' apparent purpose was to register the mark to prevent Primark from entering the South African market - a blocking strategy - and that Primark might seek to rely on ss 10(3) or (7) of the Act to resist any registration application by Truworths, though no opinion was expressed on the merits of such a challenge.
