Eminem has picked a legal fight with two “Real Housewives” over their efforts to register the name of their Reasonably Shady podcast as a trademark.

Citing his Slim Shady nickname, lawyers for the superstar (real name Marshall B. Mathers) last week quietly launched a case aimed at blocking Gizelle Bryant and Robyn Dixon (stars of the Real Housewives of Potomac) from securing a federal trademark registration on their podcast’s name.

In a petition filed on Dec. 14 at the U.S. trademark office, Eminem’s attorneys said American consumers view the term “Shady” as a “unique and distinctive” term that’s linked to the rapper – meaning they would likely think that “Reasonably Shady” was somehow connected to Eminem.

“Confusion is unavoidable,” the rapper’s lawyers wrote. “Applicant’s mark ‘Reasonably Shady’ simply looks and sounds like ‘Shady’ and suggests that it represents the services of Mathers.”

In a statement to Billboard on Tuesday (Feb. 21), Dixon and Bryant’s attorney Andrea H. Evans said the duo “intend to defend their trademark application” in the face of Eminem’s accusations. “The trademarks are not confusingly similar and the services are not related,” Evans said.

Bryant and Dixon launched “Reasonably Shady” in 2021, describing it a series of “conversations about being fearless women as they recount stories from their exciting lives.” They’ve released 80 episodes since, covering dating, relationships, motherhood, style, current events and other topics.

Last year, the duo applied at the U.S. Patent and Trademark Office to secure a trademark registration on the name for a wide range of offerings, including not just producing a podcast but also selling cosmetics, candles and apparel. If granted, the registration would make it easier for Bryant and Dixon to sue someone who used the term “Shady” for similar goods or services.

But last week, Eminem’s attorneys filed their case at the Trademark Trial and Appeal Board, a court-like body within the USPTO where rival trademark owners can battle over who has better rights to a disputed name.

The rapper, who has “Slim Shady” and “Shady” for decades as the name of a dark alter ego, already owns a number of such trademark registrations on those names, covering music services and merchandise. Giving the similarity of the names, his lawyers say consumers will associate Bryant and Dixon’s proposed trademark with Eminem.

“Applicants use and registration of the mark ‘Reasonably Shady’ is likely to cause confusion in the minds of consumers,” his attorneys wrote, saying the star would be “damaged” by the registration of Bryant and Dixon’s trademark.

A rep for Eminem did not immediately return a request for comment on the case. Dixon and Bryant have until March 26 to file a formal response at the Trademark Trial and Appeal Board.
