South Cone, Inc v Casio Keisanki Kabuskiki Kaisha

South Cone, Inc (the applicant) sought to register the trade mark "CASIO" in relation to a range of goods, including calculators, watches, and electronic devices. Casio Keisanki Kabushiki Kaisha (the opponent) opposed the registration, arguing that the mark was identical to its own registered trade mark "CASIO" and that registration would be likely to deceive or cause confusion. The matter came before the Federal Court of Australia.

The primary legal issue before the Court was whether the applicant's proposed use of the trade mark "CASIO" was likely to deceive or cause confusion, within the meaning of section 64 of the *Trade Marks Act 1955* (Cth), given the opponent's prior registration of the identical mark. This involved an assessment of the similarity of the marks, the similarity of the goods, and the overall likelihood of a misrepresentation being made to the public.

The Court considered the evidence presented by both parties, including evidence of the opponent's extensive use and reputation in the Australian market under the "CASIO" trade mark. His Honour found that the marks were identical and that the goods in question were closely related, if not identical. Applying the established principles for assessing deceptive or confusing similarity, the Court concluded that there was a significant likelihood that consumers would be deceived into believing that the applicant's goods originated from, or were in some way connected with, the opponent.

Consequently, the Court upheld the opposition and ordered that the applicant's trade mark application be refused.
