“47. In my judgment the Tile Mark does not comply with the first condition for the following reasons. As Zynga rightly contends, the Tile Mark covers an infinite number of permutations of different sizes, positions and combinations of letter and number on a tile. Furthermore, it does not specify the size of the tile. Nor is the colour precisely specified. In short, it covers a multitude of different appearances of tile. It thus amounts to an attempt to claim a perpetual monopoly on all conceivable ivory-coloured tile shapes which bear any letter and number combination on the top surface. In my view that is a mere property of the goods and not a sign. To uphold the registration would allow Mattel to obtain an unfair competitive advantage.”
