On July 1, Australia’s trademark registrar ruled against Eminem in a dispute over an Australian swimwear label called Swim Shady. The headlines framed it as a rapper losing a fight over a pun. That framing misses the actual lesson. Eminem didn’t lose because a swimwear brand out-argued him on confusing similarity. He lost because his own team couldn’t prove his “Shady” registrations were being used, in Australia, to sell the products those registrations claimed to cover.
That distinction matters more to a founder scaling a six-figure brand into new product categories than the celebrity name attached to the story. This is a use-it-or-lose-it problem, and it gets more dangerous, not less, as a brand grows, because the categories most vulnerable to a use challenge are exactly the ones a growing brand tends to add last: the merchandise line, the licensed product, the class filed to protect a future that hasn’t arrived yet.
What the Registrar Actually Decided
The ruling addressed Eminem’s “Shady” and “Shady Limited” trademarks, which had covered a range of merchandise categories including clothing, footwear, headwear, bags, and leather goods. The adjudicator found the marks had not been genuinely used in Australia in those categories during the relevant period, and separately found insufficient evidence that Eminem exercised “actual control” over the sale of merchandise carrying the marks. As a result, protection for clothing, footwear, headgear, bags, and leather goods will lift on August 1, with an appeal deadline of July 22. Eminem retains his Australian rights in “Shady” for music and electronics, where genuine use was established. Notably, “Slim Shady” itself wasn’t registered as a trademark in Australia until January 2025, after Swim Shady had already launched in 2024.
Two separate findings did the damage here, and founders tend to only think about one of them.
The Use Requirement Everyone Underestimates
The first finding, insufficient evidence of genuine use, is the myth every founder eventually runs into: that registering a trademark is the finish line. It isn’t. Nearly every serious trademark system in the world, including the U.S., ties continued protection to continued, provable use. A registration is a right to police, not a permanent shield you file once and forget.
In the U.S., that principle shows up in two places. Every registration owner must file a Section 8 declaration of continued use between the fifth and sixth year after registration, and again with each renewal, and the USPTO does not send a reminder before the deadline passes. Miss it, and the registration is cancelled, full stop, regardless of how famous the brand has become in the interim. Separately, a mark that hasn’t been used in commerce for three consecutive years is presumed abandoned under the Lanham Act, and any third party can petition the Trademark Trial and Appeal Board to cancel it on that basis at any point in the registration’s life, not just at the renewal deadline. A famous name attached to the mark does not exempt it from either mechanism.
What Counts as Real Use, and What Doesn’t
This is where founders get tripped up long before they reach a cancellation fight, because the USPTO’s bar for acceptable use evidence, called a specimen, is more specific than most applicants expect. A mockup of a product with the mark added in design software is not a specimen. A single invoice to one customer, with no indication the product was ever generally available, usually isn’t enough either. A website screenshot showing the mark next to a product description, without a way to actually complete a purchase, gets refused constantly for failing to show the mark used in connection with an actual point of sale. What examiners want to see is the mark as an actual customer would encounter it at the moment of buying: on the product itself, on its packaging, on a checkout page that lets someone complete an order. That standard applies at filing, and it is the same standard a challenger will hold a registration to years later if its genuine use is ever questioned. A brand that has only ever produced a mockup for one class of goods has a registration that looks solid on paper and is quietly unenforceable.
The Control Problem Nobody Talks About
The second finding is the one that should worry brand owners more, because it’s less obvious and it hits exactly the growth pattern six-figure founders are living through: licensing out categories they don’t run themselves. The Australian registrar didn’t just ask whether “Shady” merchandise existed. It asked whether Eminem’s camp exercised actual control over who made it and how it was sold, and found the evidence lacking.
U.S. law has its own version of this problem, called naked licensing. A trademark owner who licenses use of a mark to a manufacturer, distributor, or merchandising partner without maintaining real quality control over how that partner uses the mark risks losing the mark entirely. Courts treat an uncontrolled license as evidence the mark has stopped functioning as a source indicator at all. This is the exact scenario a growing brand walks into the moment it licenses its name to a co-manufacturer, a licensee for a merchandise category, or a white-label partner and stops paying attention to what that partner actually does with it. The registration certificate doesn’t protect you from this. Only an ongoing paper trail of actual oversight does.
Why Fame Didn’t Save the Registration
It’s tempting to assume a globally recognized name gets special treatment from a registrar or examiner. It doesn’t, and understanding why matters for any founder whose personal brand is the product. Fame is highly relevant to one specific question in trademark law: how broad a zone of protection a mark deserves against confusingly similar competitors, because famous marks get stronger dilution protection than obscure ones. Fame has nothing to do with a separate question: whether the registration owner has actually used the mark on the specific goods it claims to cover. Those are two different inquiries, decided on two different bodies of evidence, and a strong answer to the first does not substitute for a weak answer to the second. A registrar auditing use doesn’t ask how famous you are. It asks for the invoice.
Why Multi-Class Growth Is Exactly Where This Breaks
Here’s where the Eminem case becomes directly relevant to anyone building a brand rather than defending one that’s already famous. Celebrities and creators routinely file broad, multi-class applications the moment a name has any commercial traction — music rights today, clothing and electronics tomorrow, whatever category might matter in five years. That instinct isn’t wrong. Protecting the categories your brand might expand into is smart, forward-looking portfolio strategy, and it’s exactly what I’d advise a founder scaling past six figures to do.
The mistake is filing broad and then treating every class as equally protected once the registration issues. It isn’t. Music and electronics use was apparently real and documented in Eminem’s case. Clothing and merchandise use, and control over it, apparently wasn’t, and that gap is precisely where the registration became vulnerable. A registration covering ten classes is only as strong as the weakest class’s evidence file. If you can’t produce dated invoices, marketing materials, and, if you’re licensing, a real quality-control record for a given class, that class is exposed, no matter how strong your use is everywhere else.
The Examiner’s View
In a decade examining applications at the USPTO, I saw this exact pattern from the other side of the desk: an applicant with genuine, well-documented use in their core category and thin-to-nonexistent evidence in three or four adjacent classes they’d added “just in case.” Those adjacent classes usually survived examination, because initial registration only requires a specimen at filing, not ongoing proof. What they don’t survive is a challenge years later, when a competitor or a registrar audit asks the question nobody asked at filing: are you actually still doing this, and can you prove it?
The fix isn’t to file narrower. It’s to treat every class in your registration as a commitment, not a placeholder, with an actual product roadmap behind it, dated evidence as you go, and real oversight if someone else is manufacturing or selling under your name. A portfolio built that way is durable specifically because it can survive the kind of scrutiny Eminem’s registration just failed.
