What would you do if a global pop star’s legal team sent you a cease-and-desist letter — and told you to stop using your own name?
That’s exactly what happened to Katie Perry, an Australian fashion designer who built a clothing brand from the ground up in Sydney. Her brand. Her name. Her business.
When that letter arrived in 2009, she had a choice: back down, or fight.
She fought. And in March 2026, nearly 17 years later, Australia’s highest court ruled in her favor, 3–2, against one of the most famous pop stars in the world.
It sounds like celebrity drama. But for entrepreneurs and business owners? This case is a masterclass in how trademark law actually works — and why registering your brand early might be the most important thing you do for your business.
The Background: Two Perrys, One Name
The dispute centers on two people with nearly identical names:
- Katy Perry — the global pop star behind hits like Firework and Roar
- Katie Perry — an Australian fashion designer (born Katie Jane Perry, later known as Katie Taylor) who launched her clothing brand in Sydney in 2007
Same name. Completely different industries. And a legal fight that would take nearly two decades to resolve.
The designer launched “Katie Perry” as a clothing brand first, and registered the trademark. Around the same time, the pop star was breaking out internationally with “I Kissed a Girl.”
The singer had already adopted the stage name Katy Perry. But in Australia, specifically in the clothing industry, the designer had arrived first. That single detail would become the foundation of her case.
When the Legal Battle Began
Katie Perry (the designer) wasn’t looking for a fight. She was running a small clothing brand in Sydney, the kind of business built on hard work, not headlines.
Then the letter arrived.
In 2009, as the pop star prepared for her first Australian tour, her legal team sent a cease-and-desist demanding the designer stop using the name “Katie Perry” for her clothing line.
The designer refused. She kept selling under the brand name she had already registered — because legally, that name was hers.
For years, the issue stayed unresolved while both sides continued operating. Then, in 2019, the designer went on the offensive, filing a lawsuit alleging that Katy Perry’s merchandise—including clothing sold at Australian concerts—violated her trademark rights.
That lawsuit kicked off the long chain of court battles that would eventually reach Australia’s highest court.
How the Courts Ruled
The case moved through multiple levels of the Australian court system, and the outcome flipped more than once.
2023: The Designer Wins
The Federal Court of Australia ruled that Katy Perry’s merchandise had infringed the designer’s trademark, specifically, clothing sold during Australian tours.
2024: The Singer Wins on Appeal
The victory didn’t last. An appeals court reversed course and ruled in favor of the singer, finding that Katy Perry had established a strong enough reputation in Australia that the designer’s trademark might even be subject to cancellation.
2026: The High Court Has the Final Say
The designer appealed to the High Court of Australia and won, 3–2.
The court found:
- The designer’s trademark was valid
- It did not mislead consumers
- It did not damage the singer’s reputation
- The singer’s companies had infringed the designer’s registered trademark when selling certain merchandise
Why the Designer Won — And What It Means for You
Here’s where most articles stop at the legal summary. We’re not going to do that because the real value of this case isn’t what happened in court. It’s what it means for your brand, right now.
1. She filed early. You should too.
You’re building something right now. A name, a brand, a reputation. The moment that name starts to matter to you, the moment you’d be devastated to lose it, that’s when you file. Not when you’re bigger. Not when you have more time. Not “eventually.”
Now.
The designer launched her clothing brand in 2007 and registered her trademark shortly after. That single decision gave her legal standing that held up for nearly 17 years against a global pop star with virtually unlimited resources. Early registration is one of the most powerful things you can do for your brand.
2. Filing in the right category matters.
Katy Perry eventually registered her stage name as a trademark in Australia. But not for clothing. Her registrations mainly covered music recordings and entertainment services.
Trademarks are registered by specific categories called “classes.” Clothing is one class. Music is another. Entertainment services are another. If you’re not registered in the right class for your actual business, you have a gap in your protection — and someone else can exploit it.
This is one of the most common mistakes entrepreneurs make when they try to handle trademarks on their own. Getting the classes right from the start is part of what we do for every client.
3. Fame doesn’t win trademark disputes. Registration does.
Let’s be honest: most people assume the celebrity wins these things. Better lawyers, bigger budget, more name recognition. Case closed, right?
Wrong.
Trademark law doesn’t have a fame exception. The High Court ruled that shoppers were unlikely to confuse a small Australian clothing brand with a global pop star, and the designer’s earlier, properly registered trademark was held.
If that doesn’t make you feel a little better about going up against larger competitors in your industry, we don’t know what will.
A True David vs. Goliath Story
The case attracted global attention partly because of the contrast. On one side: a pop star with virtually unlimited legal resources. On the other: a small business owner in Sydney who just wanted to keep her name.
The designer has described the fight as being about more than her brand, but proving that small businesses have real legal rights worth defending.
To be clear: we root for all our clients. But we’d be lying if we said there wasn’t something satisfying about watching a well-filed, well-timed trademark registration hold up for 17 years — against all odds, and all resources.
And if a small clothing designer can defend her trademark against a global pop star and win? Your brand is absolutely worth protecting, too.

What Happens Next in the Case
The High Court ruling settled the core issue, but the case isn’t entirely over. Some remaining questions, including whether the designer waited too long to file her infringement claims, are being sent back to a lower court for further review.
The key outcome stands: the designer keeps her “Katie Perry” clothing trademark.
The Bottom Line
The Katy Perry vs. Katie Perry dispute may read like celebrity gossip. But after nearly two decades of litigation, Australia’s highest court confirmed something trademark attorneys have always known: trademark rights come down to registration, timing, and the right categories. Not fame. Not resources. Not how many people know your name.
Just who filed first and who filed correctly.

Frequently Asked Questions
Does being famous automatically win a trademark dispute?
No, and this case proves it. Trademark law is based on registration, timing, and the specific categories of goods and services involved. Fame and resources can help fund a legal battle, but they can’t override a well-filed, earlier trademark registration.
Do I need a trademark if I’m a small business?
Especially if you’re a small business. Without a registered trademark, you could be forced to rebrand, even if you’ve been using your name for years. A federal trademark registration is what gives you the legal standing to defend your brand.
What are trademark classes, and why do they matter?
Trademarks are registered for specific categories of goods and services called “classes.” Registering in the wrong class, or missing a class you actually operate in, can leave your brand exposed. This is one of the most common filing mistakes, and it’s exactly what a trademark attorney helps you avoid. How long does the trademark process take? The process typically takes 9–12 months minimum, and sometimes longer. The sooner you file, the sooner your rights are established even while the application is still pending.
