An Australian fashion designer has triumphed over global pop sensation Katy Perry in a High Court trademark dispute that has stretched over several years. In a decision that will matter to small business owners everywhere, the High Court, in a majority decision, found the designer's mark was not likely to harm the singer's reputation or cause confusion, and was not in breach of the trademark laws.
Katie Perry is not the pop star's legal name. Katy Perry, the singer, was born Kathryn Elizabeth Hudson but adopted her stage name in about 2001. Katie Perry, the designer, was born with that name, but changed to other names, including Katie Taylor. When you share a surname with someone famous, the legal right to use your own name in business suddenly becomes complicated.
The dispute over the name began in 2009, when the pop star was set to tour Australia. However, the case wasn't brought back again until 2019, when designer Katie Perry took the singer to the Federal Court of Australia. The designer said her trademark had been infringed by the sale of the singer's branded clothes, shoes and headwear.
The journey through the courts was frustratingly inconsistent. The designer won in the first instance in the Federal Court but lost on appeal. That appeal decision in 2024 suggested the game was over for Katie's small business. The designer faced the possibility of having her designer's mark de-registered after her 2023 win in the Federal Court was overturned on appeal. The appeal judges found the Katie Perry trademark was deceptively similar to the pop star's brand and was likely to cause confusion. But here's where persistence paid off.
The arguments before the High Court revealed a genuine tension in trademark law. The singer's lawyers told the High Court the Katy Perry stage name could not be divorced from the reputation of the name, when it came to marketing. Put differently: the singer's argument was that her fame in music automatically extended to clothing, even though she had not registered or actively sold branded clothes in Australia when Katie first registered her mark in 2008.
Katie Perry, the designer, said her actions were innocent, that she adopted the trademark for clothes first and applied to register the name before she had even heard of the singer. Her lawyers argued that she had used the brand name for a decade without any actual confusion. Ms Taylor's lawyers argued during the hearing that shoppers were savvy enough to distinguish between the two spellings and wouldn't connect the label to the pop star.
The appeal judges made a mistake in concluding there were grounds to cancel the trademark, the High Court determined in its majority ruling. This distinction matters. The High Court did not say the names are completely different or that confusion is impossible. It said cancellation was not the right remedy.
Costs have been awarded in Katie Perry's favour. That practical outcome will ease the financial burden of a battle that consumed years and resources.
The case offers a hard lesson for small business owners and entrepreneurs. The law offers some protection for using your own name, but it is not absolute and not always cheap to defend. The decision marks the end of a tug-of-war that has been running since 2009, when Ms Hudson became aware the designer had applied to register the Katie Perry trademark. For Katie Perry the designer, winning back her trademark means she can continue building her business under the name she was born with. For the rest of us watching, it is a reminder that trademark registration matters, timing matters, and sometimes David can still win.
