How Eminem lost part of his “Shady” trade mark rights in Australia

Eminem has lost part of his Australian trade mark protection after IP Australia found insufficient evidence of genuine use of his “SHADY” and “SHADY LIMITED” marks for clothing, footwear, bags and related goods. The decision followed a challenge by Sydney start-up Swim Shady, which successfully argued the registrations were vulnerable to removal for non-use. The case highlights the importance of actively using registered trade marks, maintaining evidence of that use and exercising control over licensed brand activity. It also serves as a reminder for businesses to register and protect key brand assets early, across relevant markets and classes.

IP Australia’s Registrar of Trade Marks has handed a significant win to Sydney start-up Swim Shady in its ongoing dispute with rapper Eminem (Marshall Mathers III).

Beyond the celebrity angle, the decision highlights important risks for businesses that rely on trade mark registrations without being able to demonstrate genuine use, effective control over licensed use and appropriate protection of key brand assets.

Why did IP Australia side with Swim Shady?

Swim Shady sells beach canopies, umbrellas, towels and apparel. Eminem opposed the brand’s Australian trade mark application, arguing the name was too similar to his Slim Shady alter ego.

While Eminem held existing Australian marks for “SHADY” and “SHADY LIMITED”, he did not apply to register “SLIM SHADY” as an Australian trade mark until after Swim Shady had launched.

Why Eminem’s trade marks were vulnerable

Swim Shady commenced non-use proceedings against Eminem’s existing “SHADY” and “SHADY LIMITED” marks in classes 18 (leather goods, bags) and 25 (clothing, footwear, headgear). The Delegate found against Eminem on three main grounds:

1. The “Shady” branding had not been genuinely used on clothing, footwear, bags or leather goods in Australia during the relevant period, and functioned as a reference to Eminem’s music career rather than as a standalone product trade mark.
2. Merchandise sales were handled by his record label, with insufficient evidence that Eminem exercised the level of control over that use.
3. Only three sales of “Shady” merchandise to Australian customers were evidenced during the relevant period.

Eminem’s marks will lose coverage for clothing, footwear, headgear, bags and leather goods from 1 August 2026, though Eminem retains “SHADY” across music and electronics categories. He has until 22 July 2026 to appeal IP Australia’s decision.

Why this dispute matters beyond Australia

The dispute spans four jurisdictions. In the US, Swim Shady holds a registered mark; Eminem’s cancellation action there has been paused pending the Australian outcome. Opposition proceedings are ongoing in the UK, and the Japanese Patent Office is reviewing Eminem’s challenge to Swim Shady’s already registered mark in that territory.

Key takeaways

While the dispute involves a high-profile celebrity brand, the underlying issues are common to businesses of all sizes. The decision reinforces the importance of maintaining trade mark registrations, documenting use and ensuring licensing arrangements are properly managed.

1. Use it or you could lose it.
   A famous name does not insulate a trade mark from a non-use challenge, particularly if genuine, controlled use in the relevant classes cannot be demonstrated.
2. Control over third-party use must be evidenced.
   Where merchandise is sold through a label or licensee, the registered owner must show it exercised adequate control.
3. Register early and across all relevant classes.
   The absence of a “SLIM SHADY” registration at the time Swim Shady launched, was a material factor in IP Australia’s decision. Businesses, celebrities and personality-driven brands should audit their portfolios regularly and file internationally before trading in a market, not after a conflict arises. It is also important to protect the actual names and trade marks that have developed significant reputation and goodwill (in this case, protection of the “SLIM SHADY” brand itself may have placed Eminem in a stronger position).

Don’t wait for a dispute to audit your trade marks

The Swim Shady decision is a timely reminder that a trade mark registration is only as strong as the use that supports it. Fame, reputation and decades of brand recognition counted for very little when Eminem failed to demonstrate genuine, controlled use of his marks on Australian merchandise.

Whether you are a global brand, a household name or an emerging business, the questions are the same: Are your marks registered in every market where you trade or plan to trade? Are they registered across every class that matters to your business? And could you quickly produce evidence of genuine and controlled use if your registrations were challenged?

If the answer to any of those is uncertain, now is the time to find out — before someone else does.
