LexiMed Pty Ltd v Lex Medicus Pty Ltd

LexiMed Pty Ltd (the applicant) sought an interlocutory injunction against Lex Medicus Pty Ltd (the respondent) to restrain the respondent from using the name "Lex Medicus" and the associated logo. The applicant, which provides medical expert witness services, argued that the respondent's proposed use of its name and logo would infringe the applicant's registered trademarks, specifically "LexiMed" and a distinctive logo. The applicant also alleged that the respondent's conduct constituted misleading and deceptive conduct under the Australian Consumer Law. The application was heard in the Federal Court of Australia.

The primary legal issues before the Court were whether the applicant had established a serious question to be tried regarding trademark infringement and misleading or deceptive conduct, and whether the balance of convenience favoured granting an interlocutory injunction. Specifically, the Court had to consider the likelihood of confusion between the applicant's trademarks and the respondent's proposed name and logo, and whether the respondent's actions were likely to deceive or mislead consumers into believing there was an association between the two entities.

In determining these issues, the Court applied the principles governing interlocutory injunctions, requiring the applicant to demonstrate a serious question to be tried and that the balance of convenience favoured the grant of an injunction. The Court assessed the degree of similarity between the respective names and logos, considering both visual and phonetic aspects, as well as the nature of the services offered by each party. The Court also considered the potential for damage to the applicant's reputation and goodwill if the injunction were not granted, and the potential prejudice to the respondent if an injunction were granted and the applicant ultimately failed in its claim. The Court found that there was a serious question to be tried regarding both trademark infringement and misleading and deceptive conduct, and that the balance of convenience favoured the applicant.

The Court ordered that the respondent be restrained from using the name "Lex Medicus" and the associated logo, and from engaging in conduct likely to mislead or deceive consumers into believing that its services are associated with the applicant, pending the final determination of the proceedings.
