Demon Hunter, the Metal Band, Challenges Netflix Over KPop Demon Hunters Trademark

Netflix’s KPop Demon Hunters has grown well beyond its beginnings as an animated movie. Its popularity has supported a major music presence, consumer products and plans for live entertainment. That growth has now created a trademark dispute with Demon Hunter, a metal band whose use of its name predates the Netflix property by more than two decades.

Hyde Lane Inc., which operates the band Demon Hunter, filed an action against Netflix, Netflix Studios and AEG Presents in federal court in California on August 18. Hyde Lane alleges that the defendants’ activities violate its trademark rights and amount to false designation of origin and unfair competition.

The dispute presents an interesting trademark question: what happens when a new entertainment property becomes so successful that its commercial footprint begins reaching markets already occupied by an established brand? The band Demon Hunter, whose frontman is not only a metal enthusiast, but also an accomplished brand strategist, seems uniquely poised to find out. 

Demon Hunter, a Grammy-nominated Christian Metal Band boasting 363,000 followers on Spotify, has used its name in the music industry since the early 2000s. During that time, the band has built a business encompassing recorded music, touring and branded products. Hyde Lane has obtained federal trademark registrations associated with several of those activities, including live entertainment, clothing, recordings, graphic novels and other merchandise.

Netflix entered the picture much later. The movie, KPop Demon Hunters, premiered in 2025 and became an unusually successful release for the streaming company. Its popularity quickly generated opportunities extending beyond the movie itself, particularly through music and branded products. Netflix Studios has filed to applications with the USPTO for the mark KPOP DEMON HUNTERS across a variety of classes.

The release of the soundtrack to the movie for purchase and the recently announced planned expansion into live entertainment are especially relevant to the lawsuit. Netflix and AEG have announced plans to bring the property to audiences through a large concert tour that includes 150 cities across the globe. For Hyde Lane, that development substantially changes the trademark landscape because both names would now be used within portions of the live music industry.

At first glance, DEMON HUNTER and KPOP DEMON HUNTERS are not identical. The legal inquiry, however, is broader than determining whether two marks match word for word. Trademark infringement generally focuses on whether the circumstances surrounding competing uses are likely to cause consumers to misunderstand the source, sponsorship or affiliation of goods or services. The similarity of the marks is one consideration, but the nature of the products and services and the markets in which they appear can also be important.

Hyde Lane's position is that the wording, “KPOP” added to DEMON HUNTER does not create enough separation between the brands, particularly as Netflix moves further into music related activities. The band argues that its existing mark remains readily recognizable within the Netflix name.

The parties’ commercial activities could therefore prove as important as the names themselves. The closer Netflix moves toward live music performances, recorded music and merchandise, the stronger Hyde Lane's argument may become that consumers are encountering the marks under increasingly similar circumstances.

The band has identified several incidents that it believes demonstrate confusion has already occurred. A consumer purchased tickets for a Demon Hunter performance in New York intending to attend an event connected with KPop Demon Hunters with his children. The purchaser later contacted the band after realizing the error.

The complaint describes another incident involving a television producer who contacted representatives of Demon Hunter while attempting to reach an individual associated with music from the Netflix property. Hyde Lane also alleges that people using social media have mistakenly connected the band's accounts with KPop Demon Hunters.

One of the more notable aspects of the lawsuit involves reverse confusion. Ordinary trademark confusion often involves a newer business benefiting from an association with an established and recognizable brand. Reverse confusion addresses a different problem. A newer company may have such extensive resources, advertising and exposure that its brand becomes more familiar to consumers than the earlier user's mark. When that occurs, consumers may encounter the original trademark owner and mistakenly assume that it is connected with the newer and more visible company.

That theory has particular relevance when businesses of dramatically different sizes are involved. In this case, the band Demon Hunter had been operating for years before the Netflix film appeared, but Netflix has the ability to expose its property to an enormous worldwide audience.

The metal band therefore contends that Netflix's prominence threatens the independent identity associated with DEMON HUNTER. Rather than consumers necessarily believing that Netflix borrowed from the band, the alleged danger is that people could eventually view the band as somehow connected with Netflix's franchise.

The lawsuit also demonstrates why trademark considerations do not necessarily end when a company selects and clears a new name. Entertainment properties frequently develop in ways that cannot be captured by their original format. A successful movie may eventually support products and services in numerous additional markets. With each expansion, the trademark environment surrounding the brand can change.

A name adopted for an animated movie, for example, may initially coexist with a music related trademark under circumstances that create relatively little commercial interaction. If that movie later generates recordings, concerts and merchandise, as has been the case of KPop Demon Hunters, the relationship between those marks can look considerably different.

That evolution is at the center of Hyde Lane's allegations. The band's argument becomes less about the existence of an animated movie and more about what Netflix is now doing with the name attached to it. The dispute highlights the value of considering future uses during trademark clearance. Evaluating only the immediate product or service may overlook existing rights that could become important if the brand succeeds and moves into additional markets.

The plaintiffs in this case are seeking both monetary and injunctive relief. Among other remedies, it wants restrictions placed on certain uses of the KPOP DEMON HUNTERS name as Netflix continues developing the property commercially. Netflix disputes the claims and has indicated that it intends to defend its use of the name.

The allegations remain to be decided by the Court, but as the litigation develops, the case could provide a useful example of how trademark principles apply when entertainment properties cross traditional commercial boundaries. It also illustrates an important consideration for trademark owners on both sides of the equation: the significance of a mark can change as the businesses using it evolve.
