Critical Health Products Pty Ltd v Westcoast Surgical and Medical Supplies Pty Ltd

Critical Health Products Pty Ltd (the applicant) sought an interlocutory injunction against Westcoast Surgical and Medical Supplies Pty Ltd (the respondent) to restrain the respondent from infringing the applicant's registered trade mark 'CRITICAL HEALTH'. The dispute concerned the respondent's use of the mark 'WESTCOAST CRITICAL CARE' on its medical supplies. The application was heard in the Federal Court of Australia.

The primary legal issue before the court was whether the respondent's use of the mark 'WESTCOAST CRITICAL CARE' constituted an infringement of the applicant's registered trade mark 'CRITICAL HEALTH' under section 120 of the *Trade Marks Act 1995* (Cth). This involved determining whether the respondent's mark was substantially identical with or deceptively similar to the applicant's registered mark, and whether the goods or services in respect of which the respondent used its mark were closely related to the goods or services for which the applicant's mark was registered.

The court considered the principles of deceptive similarity, which require an assessment of the overall impression of the marks, including their visual, aural, and conceptual elements. His Honour Nicholas Smith noted that while the marks shared the word 'CRITICAL', the addition of 'HEALTH' to the applicant's mark and 'WESTCOAST' and 'CARE' to the respondent's mark created significant differences. The court found that the marks, when considered as a whole, were not substantially identical and, importantly, were not deceptively similar in the context of the goods offered by both parties. The applicant's mark was registered for a broad range of medical and surgical goods, while the respondent's mark was used on specific items such as stethoscopes and blood pressure monitors. The court concluded that the average consumer, when encountering the respective marks on these goods, would not be confused or deceived into believing that the goods originated from the same source.

Consequently, the court dismissed the application for an interlocutory injunction.
