The dispute between Katie and Katy has been resolved.

Pop sensation Katy Perry has successfully appealed a trademark ruling against her from Australian fashion designer Katie Taylor, who operates under her birth name, Katie Perry.

A trio of judges decided to overturn the 2023 ruling that had previously favored Taylor concerning alleged trademark infringement. Essentially, the judges affirmed that Katy Perry (whose real name is Katheryn Hudson) can continue using her stage name for merchandise in Australia, regardless of Taylor’s trademark claim.

YSL News has contacted representatives for Katy Perry for their input.

The judges noted that Perry had been using her name as a trademark five years prior to Taylor starting her clothing line. They pointed out that Perry had also established a strong international presence in music and entertainment under her name, granting her the right to use it in Australia.

The judges also annulled Taylor’s trademark registration.

The judges remarked, “This situation is regrettable in that two determined women in different nations each adopted their names as trademarks without knowledge of each other’s existence.”

They also suggested that Taylor had attempted to associate herself with Perry at times, raising the risk of “consumer confusion.”

Nevertheless, the court found minimal actual confusion had arisen. In 2009, Perry had proposed that both women share rights to the trademarked name, a proposal that Taylor rejected. As a result, the judges ruled that Taylor’s trademark registration needed to be voided. They stated, “In this regard, (Taylor) essentially caused this outcome herself. Sadly, returning to a state of amicable coexistence is no longer viable.”

Expressing her disappointment, Taylor told The Guardian, “This case demonstrates that a trademark isn’t worth the paper it’s printed on.”

She added, “Building my fashion brand has been my lifelong dream since I was eleven. Now that dream, which I’ve tirelessly pursued since 2006, has been taken away from me.”

Perry, known for chart-topping hits like “California Gurls” and “Firework,” is currently on tour to promote her album “143.” She is set to return to Australia for performances across the country next summer.

The album, which debuted in September, hasn’t been well-received. Following a rocky launch marked by a contentious music video for the single “Woman’s World,” which Perry defended as satire, critics labeled the album a “massive flop” and a “failed attempt” to revive her prior success.
