When a Small Business Wins a Trade Mark Dispute: Lessons from the Katy Perry Case

13 March, 2026

On 11 March 2026, the High Court of Australia delivered an important decision in Taylor v Killer Queen LLC, a trade mark dispute between an Australian fashion designer and global pop star Katy Perry.

The case highlights an important principle in trade mark law in Australia: registering your trade mark early can protect your brand — even against a much larger and more famous opponent.

The two parties involved

On one side was Katie Taylor, a Sydney-based fashion designer. Born Katie Jane Perry, she started building her own fashion label using her birth name “Katie Perry” in 2007. As part of developing her brand, she applied to register the trade mark “Katie Perry” for clothing in Australia in September 2008.

On the other side was Katy Perry, one of the world’s most famous pop stars.
Katy Perry (real name Katheryn Hudson) had already achieved global fame as a singer and performer. She later registered the trade mark “Katy Perry” in Australia, but only in relation to music recordings and entertainment services, not clothing.

How the dispute unfolded

Despite not having registered the mark for clothing, companies associated with the singer began selling “Katy Perry” branded clothing in Australia during and after her tour in 2009.

Katie Taylor believed this use infringed her registered trade mark for clothing.

After years of coexistence in the market, the dispute escalated. In 2019, Ms Taylor commenced legal proceedings in the Federal Court of Australia alleging trade mark infringement.

In response, Katy Perry’s companies filed a cross-claim, arguing that Ms Taylor’s trade mark should be cancelled because the singer’s reputation was so well known that consumers would likely associate the name with the pop star.

The case went through several stages of litigation. The trial judge initially ruled largely in favour of Ms Taylor. However, the Full Federal Court later overturned that decision and ordered that her trade mark be cancelled.

Ms Taylor then appealed to the High Court of Australia, the country’s highest court.

The High Court decision

• The High Court ruled in favour of Ms Taylor and restored her trade mark registration.
• The Court held that the reputation of “Katy Perry” in music and entertainment could not automatically extend to clothing, particularly because the singer had not sold clothing in Australia before Ms Taylor filed her trade mark application.
• In other words, fame in one industry does not automatically create legal rights in another.

Key lessons for business owners

This decision provides several practical lessons for businesses building a brand.

• First, register your trade mark early. The filing date of Ms Taylor’s application played a critical role in the outcome.
• Second, trade mark reputation must relate to specific goods or services. Fame in one industry does not automatically give rights in another.
• Third, a registered trade mark offers real legal protection, even when facing a much larger and more famous competitor.

A practical reminder for small businesses

If you are building a brand, it is important to:

• register your trade mark early
• use your trade mark consistently in business
• keep records showing how your brand is used
• seek legal advice before a dispute arises

Early trade mark protection in Australia can help avoid costly disputes later and place your business in a stronger legal position.
