Australian designer Katie Perry has just won her long-running trademark battle against pop star Katy Perry in the High Court. The case answers a question many business owners ask: what happens when a small brand and a global celebrity share the same name? 

The dispute began years ago when the singer sold Katy Perry-branded clothing in Australia. The designer, who had already registered her trademark for clothing with the name Katie Perry, argued that this infringed her rights. After mixed results in earlier courts, the High Court has now confirmed that the designer’s trademark stands and that her use of the name is not misleading or harmful to the singer’s reputation. The Court also noted that the designer had operated for years without any evidence of customer confusion. 

What this means for business owners

This decision highlights how important it is to secure your brand early and use it consistently. Even well-known names cannot automatically override an existing registered trademark. For small businesses, this is a reminder that a properly registered mark can be a powerful shield, even against much larger players.

What you should check

• Whether your business name, product name or logo is actually registered as a trademark
• Whether anyone else is using a similar name in your industry
• Whether your brand has grown beyond what your current protection covers
• Whether you need help responding to someone using a name close to yours
