Justice in Australia : Designer Katie Perry definitively wins against pop star Katy Perry

After a legal saga that captivated the fashion and music industries for years, Australian designer Katie Perry won a landmark victory on Thursday, March 12, 2026, confirming her exclusive right to sell clothing under her birth name.

The dispute, which pitted her against American pop superstar Katy Perry, centered on an accusation of trademark infringement: the designer argued that she had registered the « Katie Perry » trademark in Australia as early as 2008, long before the « Firework » singer became a global music icon.

For her part, the singer claimed that her music had already gone viral at the time of recording and attempted, through a legal counter-offensive, to have the trademark registered by the local designer invalidated.

Although an Australian court initially ruled in favor of the singer in 2024, resulting in the temporary cancellation of the clothing brand, today’s appeal decision completely reverses the situation in favor of the Australian entrepreneur.

This final ruling recognizes the prior and legitimate use of the name by the designer for her business, thus ending a landmark « David versus Goliath » battle in intellectual property law.

Thanks to this ruling, Katie Perry can now continue developing her collections without fear of prosecution, thus protecting her brand identity in her domestic market.
