On 11 March 2026, the High Court of Australia delivered a dramatic ruling that closed one of the longest celebrity trademark disputes in recent history. In Taylor v Killer Queen LLC, the court ruled 3–2 in favor of Sydney fashion designer Katie Jane Taylor (née Perry) — allowing her “KATIE PERRY” clothing trademark to remain officially registered in Australia.
The ruling overturned a 2024 decision by the Full Federal Court that had cancelled the designer’s trademark. With the High Court’s final word, the trademark No. 1264761 for clothing (class 25) remains valid — marking a major legal victory for the small business owner.
The dispute involved global pop superstar Katy Perry, whose real name is Katheryn Elizabeth Hudson, and her companies Killer Queen LLC and Kitty Purry Inc..
What began as a simple trademark registration in 2008 turned into a high-profile legal fight spanning nearly 17 years, frequently described in headlines as a “bitter 16-year battle.”
But how did a Sydney loungewear brand end up facing one of the world’s biggest pop stars in court? The answer lies in a timeline that stretches back to the moment before the singer’s global fame exploded.
The Two Women Named “Katie Perry”: How a Trademark Dispute Began
At the heart of the dispute were two completely different careers sharing nearly identical names.
The Designer
Katie Jane Taylor, originally Katie Jane Perry, is a Sydney-based fashion designer who launched a luxury loungewear brand in 2007. Based in Hunters Hill, she built her small label independently and chose the brand name “Katie Perry” simply because it was her real name.
Crucially, Taylor said she had never heard of the singer when she started her business.
Her early brand steps included:
- April 2007: Registered the business name “Katie Perry”
- May 2007: Purchased the domain katieperry.com.au
- 29 September 2008: Filed a trademark application for clothing
- 21 July 2009: Trademark officially registered
She only discovered the singer months later — when I Kissed a Girl by Katy Perry became a global hit in mid-2008.
The Pop Star
Meanwhile, the American singer had already adopted the stage name Katy Perry in 2002, but her major breakthrough came in 2008 with the album One of the Boys.
The success of songs like I Kissed a Girl rapidly turned Perry into a worldwide celebrity.
However, her Australian trademark registration in 2011 for “KATY PERRY” specifically excluded clothing (class 25).
Despite this, clothing merchandise was sold during tours through:
- Kitty Purry Inc.
- Distributor Bravado
- Online stores and pop-up retail outlets
This merchandising activity would later become central to the lawsuit.

Inside the Early Legal Clash and the 2009 Emails
The dispute intensified in 2009, when lawyers representing Katy Perry attempted to stop the designer’s trademark registration.
They issued cease-and-desist letters and filed an opposition.
During the legal proceedings, internal emails from the singer’s team surfaced. One message from her manager, Steven Jensen, reportedly reassured the singer that they had not attempted to prevent the designer from trading.
In response, the singer sent an internal reply expressing frustration.
Despite this dispute, the designer’s trademark was officially registered in July 2009.
The singer subsequently amended her own trademark application to exclude clothing, acknowledging the potential conflict.
A proposed co-existence agreement was offered but ultimately rejected by the designer.
Years of Quiet Conflict: Merchandise Sales Continue
From 2010 to 2018, the conflict simmered without reaching court.
During this period:
- The singer’s companies continued selling clothing merchandise in Australia
- Products were sold through concert tours and retailers like Target
- The designer continued operating her small-scale fashion business
According to the court record, the designer did not immediately sue due to lack of litigation funding.
This financial reality would later become an important factor in the case.
The Federal Court Showdown: 2023 Ruling
The dispute finally entered the courtroom on 24 October 2019, when the designer filed an infringement claim in the Federal Court of Australia.
In 2023, Justice Brigitte Markovic ruled in favor of the designer.
Key findings included:
- Merchandise sales during the 2014 Prismatic Tour infringed the trademark.
- The singer’s company Kitty Purry Inc. was described as “assiduous infringers.”
- The court rejected attempts to cancel the designer’s trademark.
However, the legal battle was far from over.
The 2024 Appeal: A Stunning Reversal
In 2024, the Full Federal Court overturned the earlier decision.
Judges ruled that the singer’s reputation and the common practice of pop-star merchandise could create confusion among consumers.
As a result:
- The designer’s trademark was cancelled.
- The case appeared to swing decisively toward the singer.
But the designer took the dispute to the country’s highest court.
High Court Judgment 2026: The 3-2 Decision Explained
On 11 March 2026, the High Court of Australia delivered its final ruling.
The majority of judges — Michelle Gordon, James Steward, and Jacqueline Gleeson — sided with the designer.
Two justices dissented.
Key Legal Findings
The court concluded:
- The singer’s pre-2008 reputation was mainly in music and entertainment, not clothing.
- Pop-star merchandising does not automatically create trademark rights in clothing.
- The two brands were unlikely to confuse ordinary consumers.
Justice Steward also emphasized a fundamental legal principle:
A party should not benefit from its own wrongdoing — a doctrine known as nullus commodum capere potest de injuria sua propria.
The court reinstated the original ruling and restored the designer’s trademark.
Statements from Both Sides After the Landmark Decision
After the ruling, Katie Taylor described the outcome as a victory for small businesses.
She stated:
“This case has never just been about a name. It has been about protecting small business in Australia… and showing that we all matter.”
The singer’s representatives responded that Katy Perry never attempted to shut down the designer’s company.
They reiterated that:
- A co-existence agreement was offered in 2009
- The designer waited 10 years before filing suit
No direct public statement from the singer herself has been reported.
Why the “Katie Perry vs Katy Perry” Case Made Global Headlines
Major media outlets including BBC, CNN, and The Guardian covered the story extensively.
Several factors made it headline-worthy:
- A celebrity vs small business narrative
- A 17-year legal timeline
- The unusual situation of two nearly identical names
Importantly, the case was never about the singer’s music career.
It focused solely on clothing merchandise sold in Australia.
Why This Landmark Trademark Decision Matters for Small Businesses
Legal experts say the decision could become a major reference point for trademark disputes involving celebrities.
The ruling confirms:
- Existing small businesses can retain trademark rights
- Celebrity fame alone doesn’t override earlier registrations
- Courts consider actual consumer confusion, not assumptions.
For entrepreneurs, the message is clear: trademark law can still protect independent brands—even against global fame.
What Happens Next in the Case
While the High Court decision is final on the trademark issue, the dispute is not completely finished.
The case has been sent back to the Full Federal Court to address remaining issues, including:
- Possible damages
- Any further consideration of delay in filing the lawsuit
However, one key outcome is now settled.
The “KATIE PERRY” clothing trademark remains officially registered in Australia.
And after nearly two decades of legal battles, the small Sydney fashion label has secured a historic victory against one of the biggest names in pop music.
