1. A trademark is not descriptive merely because one component word refers to a characteristic; if the mark as a whole does not describe the essential features of the product, it is capable of protection. 2. Prior use rights under section 10 of the Trade Marks Act require that the user of the unregistered mark commenced continuous and bona fide use from a date anterior to the registration (or use, whichever is earlier) of the registered trademark. Use that commences after registration does not attract prior use protection. 3. Trademark infringement under section 8(1) requires proof of five elements: (a) unauthorized use, (b) of a trademark, (c) in relation to products or services, (d) in respect of which the trademark is registered, (e) that is identical or so nearly resembling as to be likely to deceive or cause confusion. 4. When comparing marks for confusing similarity, the court must consider the dominant features of the marks, the overall visual, aural and conceptual impression, and the likely impact on a notional customer of average intelligence with imperfect recollection. 5. In passing off claims, goodwill and reputation must be affirmatively proved through evidence such as sales figures, advertising expenditure, distribution scale, and market recognition. Mere assertions of trading history are insufficient. The relevant date for assessing goodwill is when the defendant entered the market. 6. An account of profits under section 9A(2) of the Trade Marks Act is available as a remedy for trademark infringement regardless of whether passing off is established.
