46. The ascertainment of an essential feature is not to be by ocular test alone but if a word forming part of the mark has come in trade to be used to identify the goods of the owner of the trade mark, it is an infringement of the mark itself to use that word as the mark or part of the mark of another trader for which confusion is likely to result . The likelihood of confusion or deception in such cases is not disproved by placing the two marks side by side and demonstrating how small is the chance of error in any customer who places his order for goods with both the marks clearly before him, for orders are not placed, or are often not placed, under such conditions. It is more useful to observe that in most persons the eye is not an accurate recorder of visual detail and that marks are remembered rather by general impressions or by some significant detail than by any photographic recollection of the whole”. In the decision reported as (1951) 68 RPC 103 at page 105, De Cordova v. Vick Chemical Co., the plaintiffs were the proprietors of a label containing the words “Vick's VapoRub” as the essential feature, registered in Jamaica, and the defendants used a similar label with the words “Karsote Vapour Rub” as the essential feature, and it was shown that the expression “VapoRub” had become distinctive of the plaintiff's goods in Jamaica, an action for infringement was successful.
