American pop icon Katy Perry reignites her court feud with Aussie mum Katie Perry

American pop star Katy Perry rekindles her feud with Australian mother Katie Perry and appeals allegation she infringed Sydney woman’s trademark

American pop star Katy Perry is appealing an Australian court decision that found she infringed the trademark of a Sydney designer.

In April, Katie Jane Taylor, a self-described “Aussie battler,” sued the hitmaker of I Kissed A Girl, 38, in federal court for trademark infringement for selling clothes.

A mother of two, Taylor has operated a clothing label under her birth name Katie Perry since 2006 and has owned the trademark in Australia for over a decade.

The Sydney designer sued the singer – whose real name is Katheryn Elizabeth Hudson – claiming she had violated her trademark by using one that was “substantially identical or deceptively similar.”

Ms Taylor claimed that Perry had been using the trademark in Australia since 2013, selling products not only at her concerts, but also in stores such as Myer and Target.

Judge Brigitte Markovic released her verdict after the protracted trademark dispute in April, saying it was a “story of two women, two teenage dreams and one name.”

Ms. Taylor won her claims in part, while a counterclaim from Perry and her company Killer Queen LLC was rejected.

Ms. Taylor started designing clothes in November 2007 when she launched her line at a school charity event and then sold them in Sydney markets in May 2008.

She had already registered her company and domain name as ‘Katie Perry’ in 2007 before the eponymous pop idol released her own merch Down Under.

In 2009, Ms. Taylor went public with her legal battle in the form of a video message to the superstar on YouTube.

This prompted an email from Perry’s manager Steven Jensen, who said the situation had been “blown out of proportion.”

Perry has since appealed the Federal Court ruling and the next hearing date has yet to be set.

Despite the backlash Ms. Taylor has received from Perry’s fans, a network of Aussie support has kept her spirited throughout the legal battle.

Even The Bachelor star Thomas Malucelli threw in his support, modeling the small business owner’s clothing range and leaving sweet comments on her Instagram page.

“You rock, my friend,” he wrote under the post in honor of her first court victory against Perry.
