or potential consumers; retail environment, circumstances in which the later mark was adopted, etc. would have a bearing on likelihood of confusion, if the goods or services are similar, and on the grant of discretionary relief. It would be evident when these criteria are tested in concrete contexts that they are not cumulative. As between the criteria, it is also not advisable to establish a cast-in-iron hierarchy but criteria such as the nature, intended purpose and the competing or complementary nature of the products/services are more central to a determination of similarity; whereas, other factors like retail environment or addressable market become crucial while considering likelihood of confusion. Hence, after taking into consideration some or all of the above criteria in the specific factual context, the determination should be made largely objectively although subjectivity cannot be eliminated. While undertaking this exercise, as held In re Australian Wine Importers, it should be borne in mind that the classification is not determinative and that goods or services in the same class under the Nice Classification may be held to be dissimilar, whereas goods or services in different classes may be held to be similar.
