In oral submissions before us, the appellants placed considerable reliance on the principle of acquired distinctiveness. This was premised on their branding purportedly having arisen from being known as “Luke’s” simpliciter. In our view, this argument was misplaced. Even if “Luke’s” may have been a convenient shorthand reference, “Luke’s” simpliciter was never used by the appellants in a standalone fashion on their business cards, Internet website or social media. We acknowledged that there are instances where “Luke’s” simpliciter was used on the shopfront to the appellants’ restaurants and the restaurant’s cutlery. However, this use was inconsistent as their restaurant windows used the composite nine-word mark. This inconsistency also applied to the appellants’ use of their unregistered logo in various forms. The various instances of inconsistent usage thus compromised the appellants’ trade mark infringement claim. Put differently, the appellants’ argument on acquired distinctiveness leveraged on usage of their unregistered logo and the restaurant’s cutlery to shore up their case on trade mark infringement. In our view, such an approach was not permissible.
