Killer Queen, LLC v Taylor

In the case of Killer Queen, LLC v Taylor, the primary dispute involved the alleged infringement of a registered trade mark by two individuals, Katie Taylor and Katy Hudson, who were using the name "KATIE PERRY" in their respective commercial activities. The case was heard in the Federal Court of Australia. The primary judge ruled in favour of the plaintiff, Killer Queen, LLC, finding that Taylor and Hudson had infringed the plaintiff's trade mark. The court was required to decide several legal issues, including whether the registered trade mark was properly specified in the application, the meaning of "clothes" in the context of the trade mark registration, the application of the own name defence, and the discretion to cancel a trade mark registration due to the likelihood of deception or confusion.

The court found that the primary judge erred in concluding that the "KATIE PERRY" Mark should remain on the Register of Trade Marks. The court held that the specification of goods and services in the trade mark application was insufficient, as the term "clothes" did not encompass all the products being sold by Taylor. Furthermore, the court found that the own name defence did not apply to Hudson, as she had not used the infringing mark herself. The court also determined that the discretion to cancel a trade mark registration should have been exercised due to the likelihood of deception or confusion caused by the registration. Consequently, the appeal was allowed in part, and the cross-appeal was allowed in part. The registration of the trade mark was cancelled, and the costs of the appeal and cross-appeal were awarded to the appellants. The decision below was reversed, and the case was remitted to the primary judge for re-determination of the costs of the proceeding.
