Katy Perry wins trademark battle against Australian designer Katie Perry

An Australian appeals court has handed pop star Katy Perry a decisive victory in a seven-year trademark dispute, overturning a previous ruling and stripping fashion designer Katie Jane Taylor of the brand identity she had built around her birth name. The three-judge panel issued its decision Thursday, reversing a 2023 federal court ruling that had favored Taylor, a Sydney-based designer who sells clothing under the name Katie Perry—the same name the international musician uses professionally, though spelled differently.

The case began in October 2019 when Taylor accused the singer of trademark infringement, arguing that merchandise sold under the Katy Perry name in Australian retailers like Myer and Target created brand confusion. Taylor had registered her Katie Perry trademark in 2008, five years before the singer began selling tour merchandise in Australia. She claimed the similarity between the names—one spelled Katy, one Katie—would confuse ordinary consumers about which products came from which source. The initial 2023 ruling agreed with her, finding that the singer's company, Kitty Purry, had infringed Taylor's trademark during the 2014 Australian tour.

But the appeals court saw the matter differently. The judges found that Taylor had actually registered her trademark after becoming aware of the singer's growing international reputation. More significantly, they noted that in July 2009, Katy Perry had proposed a coexistence agreement—a legal arrangement that would have allowed both women to use their names without conflict. Taylor rejected the offer. The court called this a missed opportunity for "peaceful coexistence" and suggested Taylor had brought the outcome upon herself by refusing compromise and then pursuing legal action.

One of the judges, in language that captured the poignancy of the dispute, described it as "a tale of two women, two teenage dreams and one name." The panel acknowledged the genuine tragedy of the situation: both women had worked hard to build businesses using their own names as trademarks, and both had initially been unaware of each other's existence. Yet the law, as the judges applied it, favored the woman with the larger global platform. The court found that while some devoted fans might notice the spelling difference between Katy and Katie, an ordinary consumer with imperfect recollection would likely assume both products came from the same source—the famous singer.

On Friday, the court revoked Taylor's trademark registration entirely. She now faces a substantial costs order and would need to seek special leave from Australia's High Court to continue fighting. Taylor responded to the loss with visible anguish. Speaking to the New York Post, she said she had "lost everything, including my trademark." She described the label as a dream she had harbored since age eleven and had actively pursued since 2006. The legal battle, she said, had caused her nightmares and insomnia, compounded by harassment from the singer's fans online. In a blog post, she characterized the dispute as a "David and Goliath case," the smaller player outmatched by a global superstar's resources and reach.

Taylor suggested she might relocate to a country where the name Katie Perry held no commercial significance, effectively abandoning the brand she had spent nearly two decades developing. The singer has not publicly commented on her victory. She is scheduled to return to Australia for her first tour in six years in June, following a brief appearance in September at the AFL Grand Final.
