In June 2025, Disney and NBCUniversal jointly filed a landmark lawsuit against Midjourney—a leading AI image generation platform—in the U.S. District Court for the Central District of California. The case may define how copyright law applies to generative AI models and how far tech innovation can go before crossing legal boundaries.

I. Case Snapshot: From Frozen to Star Wars, AI Imitation Goes Too Far?

According to the complaint:

• Midjourney allows users to generate highly recognizable characters from franchises like Star Wars, Frozen, The Simpsons, and Minions using simple text prompts;

• The company allegedly trained its models on copyrighted material without permission;

• Generated outputs are so close to the originals that they may confuse the public or imply unauthorized endorsement;

• This results in both copyright infringement and trademark dilution.

For example, prompting “Cyberpunk Elsa with sword” could produce images that look indistinguishable from a Disney-concept design, potentially misleading viewers.

To Disney and Universal, this isn't innovation—it’s commercialized appropriation.

II. Key Legal Questions: Does “Learning” from Copyrighted Work Equal Infringement?

This lawsuit raises several critical legal questions for the age of generative AI:

1. Is using copyrighted works to train AI models “fair use”?

Midjourney will likely argue that training on copyrighted images qualifies as “fair use” due to its transformative and non-literal nature. But the plaintiffs claim:

• The use is commercial;

• Outputs are highly recognizable and substitutive;

• No license or payment was obtained.

This could become the most consequential fair use case since Google Books.

2. Is Midjourney liable for user-generated content?

Midjourney might claim to be a neutral tool, like Photoshop. But Disney and Universal argue that:

• Midjourney actively encourages infringing prompts in its guides;

• The company profits from users generating infringing works;

• This constitutes contributory and vicarious liability.

3. Are there trademark and consumer confusion issues?

The plaintiffs also allege violations under the Lanham Act. Users might mistakenly believe that AI-generated images are official collaborations, thereby damaging the brand and misleading consumers.

III. Strategic Implications: The Copyright Battlefront Has Shifted

This case is more than a legal battle—it’s a strategic escalation between content giants and AI developers.

If Disney and Universal succeed:

• AI companies may be forced to disclose and license training datasets;

• Prompt filtering and content moderation will become essential compliance tools;

• Open-source and startup AI projects may face significant legal and financial hurdles.

If Midjourney prevails:

• It could set a precedent that favors innovation and fair use in AI;

• The boundaries of copyright in the digital age will shift dramatically.

IV. What This Means for China’s Tech Industry

Chinese AI and content startups should take note of three key takeaways:

1. Training data compliance: Avoid using unlicensed visual content—especially from well-known franchises;

2. Output-layer control: Implement prompt filters to restrict generation of protected characters or logos;

3. Reverse opportunity: With strong IP (e.g., Three-Body Problem, Nezha, Honor of Kings), Chinese IP holders may explore licensing AI training datasets or enforcing rights globally.

V. Final Thoughts: Law Redrawing the Lines in an AI World

AI can create—but that doesn’t mean it can copy freely. No matter how advanced, technology still needs to respect legal boundaries.

This Disney v. Midjourney lawsuit is likely to become a cornerstone case that redefines what constitutes authorship, ownership, and infringement in an age where machines generate content at scale.

The future is here—and the rules are being rewritten in real time.
