In January 2025, we published an article examining the ongoing dispute between Australian fashion designer Katie Perry and international pop star Katy Perry. At the time, the matter had already travelled through multiple courts, with outcomes favouring each party at different stages.
Now, the High Court of Australia has delivered its final decision in Taylor v Killer Queen LLC [2026] HCA 5, bringing this long-running trade mark battle to a close.
Background to the Dispute
Katie Jane Taylor (born Katie Jane Perry) is an Australian fashion designer who established a self-funded small business. On 29 September 2008, Ms Taylor applied to register the trade mark “KATIE PERRY” in respect of clothing.
Katheryn Hudson, better known as Katy Perry, has performed under that stage name since 2002 and enjoys global recognition as a music artist.
The dispute arose when the singer sought to cancel the designer’s registered trade mark. The argument centred on whether use of “KATIE PERRY” for clothing would be likely to deceive or cause confusion among consumers, given the singer’s fame.

A Long Road Through the Courts
This matter unfolded over several years, moving through multiple levels of the Australian court system. At various points, decisions were handed down in favour of both the designer and the singer, reflecting the complexity of balancing:
- Established trade mark rights
- Reputation and fame
- The likelihood of consumer confusion
The High Court’s Decision
In a majority decision, the High Court has now ruled in favour of the Australian designer.
The Court found that use of the “KATIE PERRY” mark in relation to clothing was unlikely to deceive or cause confusion, even taking into account the singer’s reputation in Australia. As a result, the designer’s trade mark registration stands and is not in breach of Australian trade mark law.
What This Means
This decision represents a significant outcome for small businesses, particularly those operating in competitive or brand-sensitive markets.
It reinforces an important principle:
Trade mark rights are grounded in registration, use, and context, not simply global fame.
For Ms Taylor, it marks the culmination of a lengthy legal journey and a clear victory against a globally recognised brand.
Key Takeaways for Businesses
- Comprehensive Trade Mark Coverage
Ensure your trade mark registration accurately reflects all goods and services you intend to protect. Broader specifications can help avoid enforcement limitations later. - Negotiate Early Agreements
Where potential conflicts arise, consider entering into coexistence agreements to clearly define each party’s rights and boundaries. - Understand Concurrent Use Risks
If another party is using a similar mark, be prepared to address concurrent use arguments, particularly where they have established reputation or prior use. - Consider Practical Realities
Courts assess real-world context, including how consumers perceive brands. A grounded understanding of your market position and that of others is critical when enforcing rights.
