Where a registered trade mark and an allegedly infringing mark share an identical dominant word element ('iCOLLEGE') and are used in relation to identical services (education and training in class 41), the marks are so nearly resembling as to be likely to deceive or cause confusion within the meaning of section 34(1)(a) of the Trade Marks Act 194 of 1993, notwithstanding differences in font, capitalization, or additional descriptive words. Similarity on any one level - visual, aural or conceptual - is sufficient to establish likelihood of confusion. The court must apply the notional use test and consider the full range of permissible use for which the mark is registered, rather than comparing only the actual specific services, teaching methods or business models employed by the parties. A disclaimed element forming part of a composite mark may be taken into account when deciding whether the infringing mark as a whole so nearly resembles the registered mark as to be likely to deceive or cause confusion, even though the proprietor cannot claim infringement based solely on use of the disclaimed feature.
