Nikon Corporation v Nison Engineering Co Pty Ltd

Nikon Corporation sought an interlocutory injunction against Nison Engineering Co Pty Ltd to restrain alleged contraventions of its trade mark rights. The dispute concerned Nison Engineering's use of the mark "NISON" in relation to engineering services and products, which Nikon alleged was likely to cause confusion with its well-known "NIKON" trade mark used for cameras and optical equipment. The matter came before Deirdre O'Brien J in the Federal Court of Australia.

The primary legal issue before the Court was whether Nikon had established a strong enough prima facie case to warrant the grant of an interlocutory injunction. This involved determining whether there was a serious question to be tried regarding Nison Engineering's alleged infringement of Nikon's trade mark, and whether the balance of convenience favoured granting the injunction to preserve the status quo pending a final determination of the proceedings.

Her Honour considered the well-established principles for granting interlocutory injunctions, including the need for a serious question to be tried and the assessment of the balance of convenience. The Court examined the degree of visual and phonetic similarity between the marks, the nature of the goods and services offered by each party, and the likely perception of the relevant consumer. The assessment of the balance of convenience involved weighing the potential harm to Nikon from continued use of the mark against the potential harm to Nison Engineering from being restrained from using its name.

The Court ultimately found that Nikon had not established a sufficient prima facie case to warrant the grant of an interlocutory injunction. Her Honour concluded that, on the material before the Court, there was not a serious question to be tried regarding trade mark infringement, and therefore the balance of convenience did not favour the grant of the injunction. Accordingly, the application for an interlocutory injunction was dismissed.
