Background: Zip Co is one of Australia's biggest buy now, pay later companies. It was founded in 2013 and is now worth around $3 billion - with 6.6 million customers across Australia, the US, and New Zealand. But Brisbane-based mortgage lender Firstmac had already registered the "Zip" trademark back in 2004...  a full nine years before Zip Co even existed.

What happened: Zip Co applied to register the trademark itself, got rejected and continued using the name anyway. During the legal battle, court evidence revealed the Zip leaders sent a calendar invite to staff titled "ATTACK FIRSTMAC TRADEMARK 'ZIP'." Zip admitted it had infringed the trademark but argued it was an "honest concurrent user" (basically, we didn't mean any harm). The High Court ultimately rejected that argument.

What else: The ruling means Zip Co will now need to rebrand its entire Australian business operation, although it can continue using the name in the US. The case has become a major reminder of how valuable brand ownership and trademarks can be... and how expensive it is to lose.

What's the key learning?

💡 Brand equity is the dollar value that a name carries. It's the customer trust, recognition and familiarity, which helps businesses attract new customers. Zip has spent over a decade building this in Australia…but now has to start from scratch.

💡 Rebranding costs go far beyond a new logo or marketing campaign. Companies can face customer confusion, SEO changes, updated legal documents, operational disruptions and the major PR costs of explaining why you're suddenly called something else.

💡 Trademark disputes can be incredibly expensive. WWE reportedly spent £35 million changing its name after losing a trademark battle with the World Wildlife Fund. For Zip, the impact is softened because around 80% of earnings now come from the US... but it's still a costly reminder to legally secure a brand name from day one.
