An Australian fashion designer named Katie Perry has won a long-running trademark dispute against global pop star Katy Perry, after Australia’s High Court ruled in her favour.

The case, which has spanned several years, centred on the use of the name “Katie Perry” for a clothing label. The Australian designer argued that she had been operating under the brand before the American singer rose to global fame.

Designer Katie Perry claimed that the pop star’s commercial activities infringed on her trademark rights. She maintained that she had established the “Katie Perry” clothing brand in Australia before the singer’s career gained international recognition.

The legal battle intensified when the singer sought to challenge the designer’s trademark registration. The pop star argued that her own name had already gained widespread recognition in the music industry around 2008, when the designer began selling clothing under the same name.

In 2024, an Australian court initially ruled in favour of the singer, ordering that the designer’s trademark for apparel be cancelled. The decision was seen as a significant setback for the local designer.

However, the case did not end there. The Australian designer appealed the ruling, taking the matter to the country’s High Court.

In its final decision, the High Court sided with the Australian designer. The court determined that there was unlikely to be confusion between the two individuals, despite the similarity in their names.

The ruling effectively allows the designer to continue selling clothing under the “Katie Perry” brand in Australia.

A representative for the singer said that despite the legal proceedings, the artist had never intended to shut down the Australian fashion business. The spokesperson said the singer’s legal action was focused on protecting her own commercial interests.

The High Court’s decision marks the conclusion of a high-profile trademark dispute that drew international attention, highlighting the challenges that can arise when public figures share similar names in global markets.
