Eminem Sues Swim Shady for Slim Shady Trademark Infringement

Eminem’s lawsuit against Swim Shady is a trademark fight in which the rapper, whose real name is Marshall Bruce Mathers III, is trying to block or cancel the Australian beach-accessories brand’s trademarks on the grounds that “Swim Shady” is a one-letter swap on his “Slim Shady” persona and is likely to confuse consumers. The case is running simultaneously in Australia, the United States, the United Kingdom, and Japan, and a key Australian ruling is expected between late April and July 2026.

Who Swim Shady Is

Swim Shady is a Sydney-based company founded by Jeremy Scott, a former executive in Australia’s National Rugby League, and his partner Elizabeth Afrakoff. It sells portable UPF 50+ beach canopies, swim bags, towels, and shorts, with its flagship beach shade retailing for $185 AUD. Scott and Afrakoff filed their Australian trademark application in March 2024 and officially launched the brand in December 2024.¹

Eminem first used “Slim Shady” as an alter ego in 1996 and registered it as a U.S. trademark in 1999. He holds U.S. registrations for “Slim Shady” across entertainment services, musical sound recordings, and clothing, plus a “Shady” registration covering apparel, with those filings dating to 2001 and 2002.² In Australia he holds trademarks for “Shady” and “Shady Limited” and filed a new application for “Slim Shady” in January 2025.³

What Eminem Is Claiming

His filings rest on two main theories. The first is likelihood of confusion: his petition argues the Swim Shady name “uniquely and unmistakably” references his persona and that the one-letter difference “does not serve to distinguish” the brand, so consumers are “likely to be confused” into thinking there is some connection to the rapper. The second is dilution: he claims the brand could “seriously injure the reputation” of his name through “blurring and tarnishment.”⁴ His attorneys have also characterized the name choice as made in “bad faith.”⁵

How Swim Shady Is Fighting Back

The founders say they intend to contest every challenge. “Swim Shady is a grassroots Australian company that was born … to protect people from the harsh Australian sun. We will defend our valuable intellectual property,” Scott and Afrakoff said in a joint statement.¹ The company is represented by Sydney-based Meyer West IP.³

Its strategy runs on two tracks. The first is defending its own applications. The second, more aggressive, is going after Eminem’s existing Australian marks. Swim Shady filed non-use applications seeking to cancel the “Shady” and “Shady Limited” registrations, arguing those marks have not been consistently used in Australia.¹

University of Sydney intellectual property scholar Olugbenga Olatunji noted that because Swim Shady filed its Australian application before Eminem filed for “Slim Shady” in Australia, the brand holds a strong positional argument. “The way intellectual property works is it’s the first in line that has the right,” he told the Sydney Morning Herald.⁵

Where the Case Stands in Each Country

Trademark protection works country by country, so the dispute is running on four parallel tracks.

Australia

Eminem’s team lodged a formal opposition to Swim Shady’s Australian application in October 2024. IP Australia accepted the application in August 2025, and Eminem formally opposed it again in October 2025.⁶ A hearing on Swim Shady’s non-use applications took place on April 1, 2026, before the Registrar of Trade Marks. A decision is expected within two to thirteen weeks. Under the Madrid System for international trademark registration, the Australian outcome could affect Swim Shady’s applications in other countries.⁸

United States

Swim Shady registered its trademark with the U.S. Patent and Trademark Office in September 2025. Days later, Eminem filed a cancellation petition with the USPTO’s Trademark Trial and Appeal Board. In February 2026, Swim Shady moved to pause the U.S. proceedings until the Australian case is resolved. That motion remains pending.7Rolling Stone AU. Eminem Swim Shady Trademark Dispute Update

United Kingdom and Japan

Eminem’s team has lodged objections in the U.K., where the opposition process is ongoing with further filings due by April 2026. In Japan, the Patent Office is reviewing the merits of his challenge to an existing Swim Shady registration.⁹

Why the Katy Perry Ruling Matters

A recent Australian High Court decision could shape how the fight plays out. In Taylor v Killer Queen LLC [2026] HCA 5, decided on March 11, 2026, the court ruled 3-2 in favor of Sydney fashion designer Katie Jane Taylor, who had registered the trademark “Katie Perry” for clothing in 2008. American pop star Katy Perry sought to cancel that mark, arguing her global fame created a likelihood of consumer confusion.

The majority held that a celebrity’s fame in entertainment does not automatically extend to other product categories. Because Katy Perry had not sold branded clothing in Australia before the designer’s 2008 filing, she lacked the required reputation in that category. The majority also found no “real, tangible danger” of confusion, noting the two brands had coexisted for over a decade without evidence of actual mix-ups.¹⁰

That ruling potentially favors Swim Shady. If celebrity reputation in music does not automatically create rights over unrelated categories like beach accessories, Eminem’s team may need to prove his “Shady” marks have been actively used in Australia for similar goods. That is exactly the weak point Swim Shady is targeting with its non-use applications.⁵

What to Watch Next

As of mid-2026, no final decisions have been issued anywhere. The most immediate milestone is the Australian Registrar’s ruling on Swim Shady’s non-use applications against the “Shady” and “Shady Limited” marks, expected between late April and July 2026.⁹

If those marks are cancelled, it would significantly weaken Eminem’s opposition to the Swim Shady brand in Australia and could ripple outward to the U.S., U.K., and Japanese proceedings. If they survive, his opposition proceeds from a much stronger footing. The U.S. TTAB case remains on hold pending the Australian outcome, while the U.K. and Japanese matters continue in parallel.¹¹
