11 March, 2026, Update: Christy Welder, a representative of Katy Perry, has reached out to us for some clarification. According to Welder, “Katy Perry has never sought to close down Ms. Taylor’s business or stop her selling clothes under the KATIE PERRY label. The Court sent the case back to the Full Federal Court to determine issues raised by Katy Perry, including Ms. Taylor’s 10-year delay in bringing her case against Katy Perry.”
The original article follows:
After nearly two decades of legal wrangling, global pop superstar Katy Perry has lost a high-profile trademark battle to an Australian fashion designer who happens to share almost the same name, Katie Perry.
In a majority ruling which took place around March 10, the High Court of Australia sided with Sydney designer Katie Jane Taylor, allowing her “Katie Perry” clothing trademark to remain valid and ordering the pop star to cover legal costs.
The dispute originally dates back to 2008, when Taylor, who was legally born as Katie Perry, applied to trademark the name for a clothing brand after selling designs at Sydney’s Paddington Markets. Like a funny twist of fate, Katy Perry’s music career at the same time was just beginning to explode following the release of her breakout hit “I Kissed a Girl.”
Come 2009, tensions began when representatives for the singer contacted Taylor about the name while preparing for the “Hello Katy” Australian tour. According to statements presented in court, Perry’s team proposed a coexistence agreement that would allow both parties to use similar names. Taylor declined, and the matter went quiet for years, as documented by Australian Lawyer Mag.
Past that period, the pop star toured Australia multiple times and sold merchandise under the Katy Perry brand, including clothing and accessories. Their conflict reignited in 2019 when Taylor filed a Federal Court lawsuit alleging that the singer’s branded apparel, ranging from shirts to shoes and headwear, violated the latter’s trademark rights.
An Astronomical Victory for Katie Perry
The legal battle actually bounced through several levels of the Australian court system. Taylor initially won in Federal Court in 2023, but the decision was overturned on appeal after judges ruled the singer had built a reputation in Australia before the clothing label launched.
Eventually, that ruling was ultimately challenged before the High Court, where the designer secured a dramatic comeback victory.
In its 3:2 decision, the High Court determined that Ms. Taylor’s trademark can remain on the register. Crucially, the judges ruled that Perry had not established a clothing-related reputation in Australia at the time the trademark was first filed.
Taylor’s lawyers argued that she had used the “Katie Perry” name for more than a decade without significant confusion among customers—a point the court found persuasive.
Meanwhile, people online were quick to make fun of the legal battle, with numerous humorous comments such as, “‘I sued a girl and I liked ittttt…'” or “THERE CAN BE ONLY ONE.” Meanwhile, some were in awe at how a less wealthy or less influential person actually won against a Hollywood icon, “The Australian one sued Katy Perry and won, but it got overturned. Crazy. I assumed the pop star was the one suing for some reason.”
