Show Notes:
Scott:
Lady Gaga brought her Mayhem tour to the 2025 Coachella Music Festival. While her performance was a critical success, there is someone who is not a fan of hers. At a minimum, not a fan of the name she chose for her tour. I'm Scott Hervey, a partner at the law firm of Weintraub Tobin, and I'm joined today by my partner, James Kachmar. We're going to talk about the trademark lawsuit filed by the surf and lifestyle brand Lost International against Lady Gaga for her use of Mayhem on today's episode of the Briefing.
James, welcome back to the Briefing. It's been a while.
James: Yes, thanks for having me back, Scott. Like you, I've been following this Lady Gaga case, and it certainly raises some interesting trademark law questions.
Scott: Oh, absolutely, absolutely. So why don't we start with the basics? So, according to the complaint, Lost International, they're a California company that was established in 1985 as a surf and lifestyle brand. They claim to have been using the mark mayhem since 1988 in connection with surfboards, surf equipment, accessories, surf videos, and clothing. Lost owns a registered trademark for Mayhem in the United States, and it was issued on August 11, 2015, and it covers various clothing items like beanies, caps, jackets, pants, sandals, shorts, and, you know, other typical beach surf wear. This particular trademark registration is for a wordmark, which means that it covers the word Mayhem without having any particular font, style or color requirements.
James: That's right, Scott. The complaint alleges that Lady Gaga released a music album called mayhem in March 2025 and announced a worldwide concert tour under the same name. Furthermore, Lost claims that prior to the album's release, Lady Gaga and associated parties began selling T shirts and other clothing items with the Mayhem mark prominently displayed, allegedly with a nearly identical design to Lost's own Mayhem products. They've even included a side by side comparison of the clothing and their Mayhem logos in their complaint.
Scott: So LOST is seeking some significant remedies.
James: Yes, they are. Lost is asking the court for a judgment that Lady Gaga has infringed their trademark rights. They are seeking monetary damages and also want an accounting of Lady Gaga's proceeds, which will result in a possible disgorgement of her profits. They want punitive and exemplary damages, interest costs, and attorney's fees. Lost is also crucially seeking injunctive relief to stop Lady Gaga from using the Mayhem mark in connection with her merchandise and promotions.
Scott: Okay, so let's dive into the legal arguments. So the complaint asserts nine causes of action. Nothing like a big complaint, right? So these. These causes of Action include federal and common law trademark infringement, false designation of origin, and false advertising under the Lanham act, false advertising under California state law, and federal and state trademark dilution, as well as unfair business practices and common law unfair competition. So I think that the federal trademark claim is going to take center stage in this lawsuit, so let's focus on that. So in California, a court analyzing a trademark infringement claim is going to look at the sleek craft factors, which are the following. The strength of the plaintiff's mark, the similarity of the marks at issue, the similarity or relatedness of the goods,
