Disney, NBCUniversal and Warner Bros. Discovery Sept. 16 filed a lawsuit against Chinese AI company MiniMax claiming the company is stealing their intellectual property without permission.

Hollywood continues its ramp up legal offensive against artificial intelligence companies as the technology evolves enabling third-parties to artificially create content on the backs of existing content.

MiniMax is marketing software to consumers called Hailuo that affords users access to studio images and videos from characters such as Spider-Man, Superman, Darth Vader, Shrek, Buzz Lightyear and Bugs Bunny, among others.

“MiniMax’s bootlegging business model and defiance of U.S. copyright law are not only an attack on Plaintiffs and the hard-working creative community that brings the magic of movies to life, but are also a broader threat to the American motion picture industry, which has created millions of jobs and contributed more than $260 billion to the nation’s economy,” read the complaint filed in U.S. District Court, Central District of California in Los Angeles.

The litigation comes after the studios say their calls to MiniMax to stop using their IP illegally were ignored.

In June, Disney and NBCU sued San Francisco-based AI company Midjourney claiming the company was marketing software featuring their IP without permission.

Disney, Warner Bros. Discovery and NBCUniversal are taking legal aim at another AI company that they allege is massively ripping off their intellectual property.

On Tuesday, the three media companies filed a lawsuit against MiniMax, a Chinese AI company that is reportedly valued at $4 billion, alleging “willful and brazen” copyright infringement. According to the lawsuit, filed in the U.S. District Court for the Central District of California, MiniMax disregards U.S. copyright law by treating the studios’ copyrighted characters as if those were its own.

“MiniMax operates Hailuo AI, a Chinese artificial intelligence image and video generating service that pirates and plunders Plaintiffs’ copyrighted works on a massive scale,” the companies said in the lawsuit, filed Tuesday. “MiniMax markets Hailuo AI as a ‘Hollywood studio in your pocket’ — an audacious self-anointed nickname given that MiniMax built its business from intellectual property stolen from Hollywood studios like Plaintiffs.”

The lawsuit continued, “The Hailuo service offers its subscribers an endless supply of infringing images and videos featuring Plaintiffs’ famous copyrighted characters. MiniMax completely disregards U.S. copyright law and treats Plaintiffs’ valuable copyrighted characters like its own.”

Disney, NBCU and WBD have also sued AI startup Midjourney, also alleging copyright infringement.

Disney, NBCUniversal and Warner Bros. Discovery said in a joint statement, “We support innovation that enhances human creativity while protecting the contributions of countless creators and the entire creative industry. A responsible approach to AI innovation is critical, and today’s lawsuit against MiniMax again demonstrates our shared commitment to holding accountable those who violate copyright laws, wherever they may be based.”

The studios provided multiple examples of MiniMax’s alleged infringement, along with images. For example, “If a MiniMax subscriber submits a simple text prompt requesting the character Darth Vader in a particular setting or doing a particular action, MiniMax generates and displays high quality, downloadable images and videos featuring Disney’s copyrighted Darth Vader (along with MiniMax Hailuo branding no less).” A Darth Vader image produced by MiniMax’s system is depicted above.

In their lawsuit against MiniMax, the studios alleged the company failed to act on their requests to avoid copyright infringement. “MiniMax’s bootlegging business model and defiance of U.S copyright law are not only an attack on Plaintiffs and the hard-working creative community that brings the magic of movies to life, but are also a broader threat to the American motion picture industry, which has created millions of jobs and contributed more than $260 billion to the nation’s economy,” the companies said in the suit.

On its website, MiniMax calls itself “a global AI foundation model company. Founded in early 2022, we are committed to advancing the frontiers of AI towards AGI via our mission Intelligence with Everyone.” The company claims its proprietary models and AI-native products have “cumulatively served over 157 million individual users across over 200 countries and regions, and more than 50,000 enterprises and developers across over 90 countries and regions.”
