SYDNEY — An Australian court has ruled that pop superstar Katy Perry infringed the trademark of a Sydney-based fashion designer who has sold her products locally under a label with her birth name "Katie Perry".

Katie Taylor, who filed the lawsuit in 2019, alleged the singer ignored the trademark and sold Katy Perry clothing to Australian customers during her concert tours in the country in 2014 and 2018 through retailers and websites.

Federal court judge Brigitte Markovic ruled that Katy Perry's company Kitty Purry partially infringed the trademark of Katie Taylor's business, which sells mostly clothes online, by promoting the singer's products through posts on social media, a court filing out on Thursday (April 27) showed.

Damages are due to decided at a later date.

"This is a tale of two women, two teenage dreams and one name," Markovic said in her judgement.

The judge dismissed a bid by the popstar seeking to cancel the Katie Perry trademark.

Taylor, whose birth name was Katie Perry, called the verdict a "David and Goliath" win for small businesses.

"Not only have I fought myself, but I fought for small businesses in this country, many of them started by women, who can find themselves up against overseas entities who have much more financial power than we do," she said in a blog post.

Representatives of Katy Perry could not be immediately reached.

The tussle between the popstar and the Australian fashion designer over the homophonous name began in 2008 when Taylor registered the "Katie Perry" brand in Australia.

Katy Perry initially tried to block the registration and later engaged lawyers to try to force the designer to cease and forever desist from using the mark but later abandoned the move, Taylor said.
