Without affecting the generality of the foregoing, a trade mark may consist of words (including personal names), indications, designs, letters, characters, numerals, figurative elements, colours, sounds, smells, the shape of goods or their packaging and any combination of such signs. A sign may constitute a trade mark even though it is used in relation to a service ancillary to the trade or business of an undertaking and whether or not the service is provided for money or money's worth. Unless the context otherwise requires, references in the Trade Marks Ordinance to a trade mark shall be construed as including references to a certification mark, collective mark and defensive trade mark: Trade Marks Ordinance (Cap 559) s 3.
