Here’s a sentence you don’t read every day: Katie Perry just beat Katy Perry in court. The High Court of Australia ruled on March 11, 2026, that fashion designer Katie Taylor, who was born Katie Perrie and trades under Katie Perry, has every right to sell clothes using her own name. The global pop star, born Katheryn Hudson, tried to stop her. For sixteen years, she fought. And she lost. The Katie Perry trademark victory sends a clear message: fame doesn’t automatically override someone’s birth name.
The confusion is baked into the case. Two women. Two similar names. One started selling clothes at Sydney markets in 2007. The other released “I Kissed a Girl” in 2008 and became a planet-sized celebrity. When the singer’s lawyers sent a cease-and-desist letter in 2009, the designer had a simple response: I was here first.
Taylor launched her clothing label in 2007, sewing pieces herself and selling at local markets. She’d never heard of the American singer. Why would she? Katy Perry wasn’t famous yet. The designer was just using the name her parents gave her.
“I was simply building a fashion business under the name I was born with,” she later testified. That simple fact became the foundation of her case. You can’t trademark a name so aggressively that you erase someone else’s existence, especially when they were there before you.
The High Court’s 3-2 decision turned on a surprisingly simple question: were people actually confused? The singer’s legal team argued that her fame was so massive it automatically covered clothing. The court disagreed.
Over more than a decade of both brands existing side by side in Australia, there was virtually no evidence that anyone bought a dress thinking it was concert merch. “There must be a real, tangible danger of deception or confusion, a mere possibility is insufficient,” the judges ruled. In other words: prove someone was actually mixed up. They couldn’t.
Court documents revealed internal emails that painted an unflattering picture. In 2009, the singer’s manager told her the designer had been trading under Katie Perry “since 2007.” Her response was immediate and profane, calling the designer a “stupid b***h” and ranting about the situation.
Justice Steward, writing in the majority decision, described the singer’s companies as “assiduous infringers”, a formal way of saying they knew about the trademark and sold merch anyway. You can’t keep breaking the rules and then ask the court to erase someone else’s rights because you got caught.
For Taylor, it means she can finally exhale. Her trademark, which was canceled by a lower court in 2024, is now fully restored. She can sell clothes under her own name without looking over her shoulder.
For small business owners watching from home, it means something bigger. “This case has never just been about a name,” Taylor said after the ruling. “It has been about protecting small business in Australia, for standing up for what is right and showing that we all matter.”
The singer’s team issued a statement insisting they “never sought to close down Ms. Taylor’s business.” But the designer spent sixteen years fighting to keep her own name. The court just told her she can.
