Walt Disney, Universal Pictures, and Warner Bros. Discovery have jointly filed a lawsuit in California accusing Chinese AI company MiniMax—maker of the generative media service Hailuo AI—of willful copyright infringement. According to Reuters, Financial Times, Axios, and Los Angeles Times reports, the studios claim that Hailuo AI enables users to generate high-quality images and videos featuring iconic characters like Darth Vader, the Minions, and Wonder Woman without authorization, and even uses such characters in its marketing. The lawsuit seeks injunctive relief and damages, arguing MiniMax ignored repeated requests to implement safeguards and treated copyrighted characters like they were its own. MiniMax, which has raised substantial funding and is reported to be targeting a valuation over US$4 billion in a planned IPO in Hong Kong, has not yet publicly responded to these allegations.

Key Takeaways
– Major entertainment companies are intensifying legal efforts to protect intellectual property rights in the face of generative AI tools, especially when AI services allow users to reproduce and distribute copyrighted characters.
– MiniMax’s Hailuo AI is accused of both producing unauthorized content involving recognizable characters and using them in marketing materials, suggesting that the dispute is not just about downstream usage but also about how the service presents itself.
– The outcome of this lawsuit could have significant consequences not only for MiniMax—especially given its IPO ambitions—but for the broader AI industry, as legal precedents around AI-generated content and copyright are still evolving.
In-Depth
The rise of generative AI tools has opened up a landscape of both creativity and legal risk, and the lawsuit filed by Disney, Universal, and Warner Bros. Discovery against MiniMax crystallizes many of the tensions at play.
According to court documents and media reports, the three studios allege that MiniMax’s product Hailuo AI allows users—and even promotes itself as a portal—to produce downloadable images and videos of famous copyrighted characters, such as Darth Vader, Minions, and Wonder Woman, without securing any licensing or permission. These claims aren’t only about what users can generate but also how MiniMax uses these characters in its advertising and branding, which the studios argue creates confusion and implies endorsement.
The legal complaint frames MiniMax’s actions as “willful and brazen,” saying it ignored requests to adopt filtering or other safeguards commonly used in the industry to prevent unauthorized use of copyrighted IP. Other generative AI platforms have been under scrutiny for similar issues (for instance, the studios earlier sued Midjourney), but this case is notable as a high-profile challenge aimed at a Chinese firm with global reach.
MiniMax is not a small player: it’s reportedly targeting a valuation exceeding US$4B via a Hong Kong IPO, serves over 150 million users globally, and has backing from major investors such as Alibaba, Hillhouse, and others.
Beyond the financial stakes, the lawsuit is significant because it presses on issues that many AI creators, users, and policymakers are watching closely: What constitutes fair use when an AI model is trained on copyrighted works? What obligations do platforms have to prevent misuse of proprietary characters and content? And how far can copyright holders go to control not just the output of AI tools, but also their marketing and user-facing branding? The courts may also grapple with damages: the studios are seeking remedies under U.S. law for each infringing work, which could amount to significant sums if many such works are found.
On the flip side, MiniMax’s side has not been heard (as of the most recent reports) in public detail, which means there may be defenses we aren’t yet seeing: possible claims of fair use, technical limitations, or argument that the usage is transformative. But even these defenses are being tested in courts worldwide. The broader implication is clear: AI firms that allow or facilitate the recreation of copyrighted characters, especially in commercial or widely accessible contexts, are under increasing legal pressure. For companies planning IPOs or international expansion, exposure to litigation like this becomes a material risk. In sum, this lawsuit could shape the next era of how generative AI is regulated, how creative industries protect their IP, and how innovators design systems with both creativity and legality in mind.
