Katie Perry wins High Court trademark case against Katy Perry
Katie Perry wins High Court trademark case against Katy Perry reports a landmark trademark decision by Australia’s High Court in favour of Sydney‑based fashion designer Katie Perry (birth name Katie Jane Taylor) in her long‑running legal battle with American pop star Katy Perry (real name Katheryn Elizabeth Hudson) over the right to use the name Katie Perry in commerce.
The dispute began almost 17 years ago, stemming from the fact that the designer had been operating a clothing and fashion label under the name Katie Perry since 2007 — before the singer became widely famous in Australia. The designer applied for trademark registration for clothing goods in 2008 and secured registration, but as the singer’s international fame exploded, especially after hits like “I Kissed a Girl,” the conflict over rights to the name intensified.
The core issue was whether the designer’s use of her own name as a trademark could stand given the global reputation of the pop star who had a similar name and was selling branded merchandise, including clothing, during her Australian tours starting in 2009. The singer’s team initially opposed the designer’s trademark, arguing that the prominence of the pop star meant consumers could be misled. At various points in the litigation, both sides won and lost in lower courts.
In 2019, the Sydney designer took the matter to the Federal Court of Australia, accusing Katy Perry and her associated companies of infringing on her trademark by selling clothing and accessories in Australia under the Katy Perry name. A Federal Court judge initially sided with the designer, but this was overturned on appeal in 2024 when the appellate judges ruled in favour of the singer, finding that the pop star’s reputation predated the designer’s trademark and should prevail.
However, the legal saga ultimately reached the High Court of Australia, the nation’s apex judicial body, which delivered a majority decision on March 11, 2026. In this ruling, the High Court concluded that the designer’s trademark did not violate Australian trademark law and that it was unlikely to cause consumer confusion between the two brands. The decision emphasized that consumers are sophisticated enough to distinguish between the clothing produced by the Sydney fashion label and the pop star’s music and merchandise, despite the similarity in names.
The court also took note of the extensive period during which the designer had used her name without demonstrable confusion or legal action, bolstering her claim that her brand was distinct and established. As a result, the High Court not only upheld her trademark rights but also ordered legal costs awarded in her favour, a significant financial and symbolic victory for the small business owner.
Representatives of Katy Perry reportedly stated that the singer “has never sought to close down” the Australian business, suggesting that the dispute was handled through legal avenues rather than direct attempts to shutter the designer’s company. Nonetheless, the case highlights the tension between global celebrity branding and the legal rights of individuals who share a similar name but operate in overlapping commercial spaces.
Katie Perry, the designer, expressed personal satisfaction with the outcome, welcoming it as a triumph not only for her business but also for small businesses and individuals defending their legal trademarks against internationally renowned personalities and corporate teams. Legal analysts characterize the case as a precedent‑setting decision in Australian intellectual property law, especially in how the courts balance fame, trademark rights, and consumer confusion in contexts where names are also personal identities.
