1. The New York Times v. OpenAI and Microsoft (2023-2026)

In December 2023, The New York Times filed one of the most high-profile AI copyright lawsuits against OpenAI and Microsoft, alleging that the companies used millions of Times articles to train ChatGPT without permission or compensation. As of 2026, this case remains ongoing and has become a bellwether for how courts will treat AI training data.

The Times argues that OpenAI's models can reproduce near-verbatim excerpts from its articles, undermining its subscription business model. The lawsuit seeks billions in damages and demands the destruction of models trained on Times content. According to Reuters reporting, OpenAI has countered that its use constitutes fair use under copyright law, as the models transform the training data into new, original outputs.

Key Legal Issues:

• Whether AI training constitutes fair use
• The economic impact of AI on journalism
• The definition of "transformative use" in the AI context
• Whether AI outputs can infringe on training data copyrights

Current Status (2026): In discovery phase, with trial expected in late 2026 or early 2027. Several other major publishers have filed similar suits and are watching this case closely.

2. Authors Guild v. OpenAI (2023-2026)

In September 2023, The Authors Guild, along with prominent authors including John Grisham, George R.R. Martin, and Jodi Picoult, filed a class-action lawsuit against OpenAI. The suit alleges that OpenAI systematically scraped copyrighted books to train its language models without obtaining licenses or providing compensation.

The lawsuit claims that ChatGPT can generate detailed summaries and analyses of copyrighted books, demonstrating that the full text was used in training. The plaintiffs argue this violates their exclusive rights to reproduce and create derivative works from their copyrighted material.

Key Legal Issues:

• The scope of copyright protection for literary works in AI training
• Whether book summaries generated by AI constitute copyright infringement
• The applicability of the "three-step test" from international copyright law
• Potential damages calculations for thousands of copyrighted works

"Writers spend years crafting their stories. When AI companies use our work without permission to build billion-dollar businesses, it's not innovation—it's theft."

John Grisham, Bestselling Author and Plaintiff

Current Status (2026): The case survived OpenAI's motion to dismiss in 2024. Class certification hearings are scheduled for Q2 2026, potentially expanding the lawsuit to represent thousands of authors.

3. Getty Images v. Stability AI (2023-2026)

Getty Images, one of the world's largest stock photo agencies, filed suit against Stability AI in both the UK and US in early 2023. The lawsuit alleges that Stability AI copied more than 12 million copyrighted images from Getty's collection to train its Stable Diffusion image generation model without permission.

Getty's case is particularly compelling because Stable Diffusion sometimes generates images with visible Getty watermarks, providing direct evidence of copying. According to The Verge's coverage, Getty argues that this isn't just copyright infringement but also trademark violation.

Key Legal Issues:

• Copyright infringement in AI image generation
• Trademark dilution through watermark reproduction
• The commercial impact on stock photography businesses
• Whether generated images constitute derivative works

Current Status (2026): The UK case is progressing faster than the US case, with a trial date set for late 2026. Several other stock photo agencies have joined as amici curiae (friends of the court).

4. Universal Music Group v. Anthropic (2023-2026)

In October 2023, Universal Music Group (UMG), along with other major music publishers representing artists like Beyoncé, Taylor Swift, and The Beatles, sued Anthropic over its AI assistant Claude. The lawsuit alleges that Claude was trained on copyrighted song lyrics without authorization.

The music publishers demonstrated that Claude can reproduce lyrics from hundreds of popular songs when prompted, suggesting the training data included extensive copyrighted music content. According to Billboard, this case represents the music industry's first major legal challenge to large language models.

Key Legal Issues:

• Copyright protection for song lyrics in AI training
• The music industry's licensing framework and AI
• Statutory damages under the Copyright Act
• Potential for compulsory licensing solutions

Current Status (2026): Settlement discussions have been reported, with UMG potentially seeking a licensing agreement rather than pursuing the case to trial. This could establish a precedent for AI-music industry collaboration.

5. Andersen v. Stability AI, Midjourney, and DeviantArt (2023-2026)

Three visual artists—Sarah Andersen, Kelly McKernan, and Karla Ortiz—filed a class-action lawsuit against Stability AI, Midjourney, and DeviantArt in January 2023. The suit alleges that these companies used billions of copyrighted images scraped from the internet to train their AI image generators without consent or compensation.

This case is significant because it directly challenges the practice of scraping publicly available images from the internet for AI training. According to ARTnews reporting, the plaintiffs argue that AI-generated art in their distinctive styles directly competes with and devalues their original work.

Key Legal Issues:

• Whether publicly posted images can be used for commercial AI training
• The concept of "style" in copyright law
• Direct infringement vs. contributory infringement
• The right of publicity and artistic identity

Current Status (2026): After a federal judge dismissed some claims in 2023, the plaintiffs filed an amended complaint. The case is now in active discovery, with both sides deposing technical experts about how AI image generators work.

6. Thomson Reuters v. ROSS Intelligence (2020-2026)

While filed earlier than most AI copyright cases, Thomson Reuters' lawsuit against ROSS Intelligence remains highly relevant in 2026. Thomson Reuters, which owns the Westlaw legal research platform, alleged that ROSS used Westlaw's copyrighted legal documents to train its AI-powered legal research tool.

According to Law.com, internal documents showed ROSS employees created fake Westlaw accounts to scrape legal documents. ROSS Intelligence shut down in 2021, but the case continued against its investors and executives, establishing important precedents about liability for AI training data acquisition.

Key Legal Issues:

• Unauthorized access to subscription databases for AI training
• Trade secret misappropriation alongside copyright claims
• Liability of investors in AI companies for infringement
• Damages calculations for database copying

"The ROSS case demonstrated that AI companies can't simply scrape proprietary databases and claim innovation. There are legal and ethical boundaries that must be respected."

Professor James Grimmelmann, Cornell Law School

Current Status (2026): The case settled in 2024 for an undisclosed amount, but court documents and rulings from the case continue to be cited in other AI copyright litigation.

7. Concord Music Group v. Anthropic (2023-2026)

In a separate action from the UMG case, Concord Music Group and other publishers filed suit against Anthropic in October 2023, representing over 500 songs from artists including Katy Perry, Outkast, and Grateful Dead. This lawsuit focuses specifically on Claude's ability to generate lyrics and discuss copyrighted songs in detail.

The publishers argue that Anthropic's business model depends on systematic copyright infringement, as Claude's value proposition includes answering questions about popular culture, which necessarily involves copyrighted music. According to Music Business Worldwide, the case seeks both injunctive relief and statutory damages that could reach into the billions.

Key Legal Issues:

• The scope of fair use for music lyrics in AI
• Whether AI companies need synchronization licenses
• Statutory vs. actual damages in AI copyright cases
• The difference between discussing music and reproducing it

Current Status (2026): Active litigation with discovery ongoing. Anthropic has argued that Claude's use of lyrics is transformative and educational, falling under fair use.

8. Tremblay v. OpenAI (2023-2026)

Authors Paul Tremblay and Mona Awad filed suit against OpenAI in June 2023, alleging that ChatGPT was trained on pirated versions of their books. This case is distinct from the Authors Guild lawsuit because it specifically alleges that OpenAI knowingly used books from piracy websites like Library Genesis (LibGen) and Z-Library.

According to The Atlantic's reporting, the plaintiffs demonstrated that ChatGPT could generate accurate summaries of their books, including plot details and character names, suggesting the full text was in the training data. OpenAI's motion to dismiss was partially denied in 2024, allowing key claims to proceed.

Key Legal Issues:

• Liability for using pirated content in AI training
• The "willfulness" standard for enhanced copyright damages
• Whether book summaries prove access to full copyrighted texts
• The role of data provenance in AI development

Current Status (2026): In discovery phase, with OpenAI being required to disclose details about its training data sources—information it has historically kept confidential.

9. Kadrey v. Meta (2023-2026)

Author Sarah Silverman and other writers filed a class-action lawsuit against Meta (Facebook) in July 2023, alleging that Meta's LLaMA language models were trained on copyrighted books without authorization. Similar to other author lawsuits, the plaintiffs argue that Meta used pirated book collections to train its AI.

What makes this case unique is Meta's position as a major technology company that released LLaMA as an open-source model. According to TechCrunch, this raises questions about liability for downstream uses of open-source AI models trained on potentially infringing data.

Key Legal Issues:

• Copyright liability for open-source AI models
• Meta's responsibility for how others use LLaMA
• The intersection of open-source philosophy and copyright law
• Whether releasing AI models constitutes distribution of derivative works

Current Status (2026): Meta successfully dismissed some claims in 2024, but core copyright infringement claims remain. The case is proceeding toward class certification.

10. Doe v. GitHub, Microsoft, and OpenAI (2022-2026)

In November 2022, a class-action lawsuit was filed against GitHub, Microsoft, and OpenAI concerning GitHub Copilot, an AI coding assistant. The plaintiffs, who include prominent open-source developers, allege that Copilot was trained on billions of lines of code from public GitHub repositories, violating open-source licenses.

This case is particularly significant because it involves not just copyright but also contract law, as many open-source licenses require attribution and license preservation. According to WIRED's coverage, Copilot sometimes generates code that's nearly identical to copyrighted code in its training data, complete with original comments and variable names.

Key Legal Issues:

• Open-source license violations (GPL, MIT, Apache, etc.)
• Copyright infringement in code generation
• Whether AI-generated code can violate license terms
• The relationship between copyright and contract law in AI

"Open source is built on trust and reciprocity. When AI companies train on open-source code but don't respect the licenses, they're undermining the entire ecosystem that made their tools possible."

Matthew Butterick, Attorney representing the plaintiffs

Current Status (2026): After several rounds of amended complaints, the case survived GitHub's motion to dismiss in 2024. Discovery is ongoing, with particular focus on how Copilot handles license compliance.

Common Legal Themes Across AI Copyright Lawsuits

As we analyze these ten landmark cases in 2026, several common legal themes and questions emerge that will likely shape the future of AI regulation:

The Fair Use Doctrine

Nearly every AI copyright lawsuit centers on whether AI training constitutes "fair use" under copyright law. According to the U.S. Copyright Office, fair use analysis considers four factors:

1. Purpose and character of use: Is the use transformative and non-commercial?
2. Nature of the copyrighted work: Is it factual or creative?
3. Amount and substantiality: How much of the work was used?
4. Effect on market value: Does the use harm the original work's market?

AI companies argue their use is highly transformative—taking copyrighted works and creating entirely new tools that don't compete with the originals. Rights holders counter that AI models can reproduce substantial portions of training data and directly compete with human creators.

The Training vs. Output Distinction

A crucial question in 2026 is whether copyright infringement occurs during AI training, during output generation, or both. Some legal scholars argue that training is the key moment of copying, while others focus on whether AI outputs infringe on copyrighted works.

International Implications

While most high-profile cases are in U.S. courts, AI copyright issues are global. The European Union's AI Act and Digital Single Market Directive include provisions about AI training data, while the UK has proposed a text and data mining exception that could affect AI development. According to the European Commission, these regulatory differences could lead to fragmented AI development approaches.

The Economic Impact on Creators

Beyond legal technicalities, these lawsuits reflect real economic concerns. If AI can generate content similar to human creators without compensating them, it could fundamentally alter creative industries. The cases in 2026 are forcing courts to balance innovation incentives with creator protections.

What These Lawsuits Mean for Different Stakeholders

For AI Companies

AI companies face significant legal uncertainty in 2026. Many are now:

• Developing more transparent data sourcing practices
• Exploring licensing agreements with content owners
• Creating "opt-out" mechanisms for creators
• Building synthetic training data to reduce copyright risk
• Implementing stronger content filtering in outputs

For Content Creators

Artists, writers, musicians, and other creators should:

• Understand their rights regarding AI training data
• Consider registering copyrights to strengthen legal claims
• Join collective licensing organizations
• Use tools to detect AI-generated content in their style
• Advocate for legislation protecting creator rights

For Businesses Using AI

Companies deploying AI tools face potential liability risks and should:

• Conduct due diligence on AI vendors' training data practices
• Include indemnification clauses in AI service contracts
• Implement policies for reviewing AI-generated content
• Stay informed about evolving legal standards
• Consider insurance products covering AI-related risks

Potential Outcomes and Future Scenarios

As these cases progress through 2026 and beyond, several potential outcomes could reshape the AI landscape:

Scenario 1: Broad Fair Use Protection

If courts rule that AI training is transformative fair use, it could accelerate AI development but potentially harm creator compensation. This might lead to legislative action to rebalance interests.

Scenario 2: Licensing Requirements

Courts might require AI companies to license training data, similar to how streaming services license music. This could create new revenue streams for creators but increase AI development costs.

Scenario 3: Output-Based Liability

Rather than focusing on training data, courts might hold AI companies liable only when outputs substantially reproduce copyrighted works. This would shift responsibility to implementing better filtering systems.

Scenario 4: Legislative Solutions

Congress or international bodies might create new legal frameworks specifically for AI, potentially including compulsory licensing schemes, creator compensation funds, or new exceptions to copyright law.

Frequently Asked Questions (FAQ)

Is it legal to use AI tools like ChatGPT or Midjourney for commercial purposes?

As of 2026, using AI tools for commercial purposes is generally legal, but there are risks. The lawsuits discussed above don't directly affect end users of AI tools—they target the companies that created them. However, if you use AI to generate content that infringes on someone's copyright (for example, creating images in a specific artist's style or reproducing copyrighted text), you could face liability. Always review AI-generated content for potential copyright issues before commercial use.

Can I copyright AI-generated content?

According to the U.S. Copyright Office, works created entirely by AI without human authorship cannot be copyrighted. However, works that involve significant human creative input alongside AI assistance may be eligible for copyright protection. The key is demonstrating human creativity in the selection, arrangement, or modification of AI-generated elements.

What is "fair use" and how does it apply to AI?

Fair use is a legal doctrine that allows limited use of copyrighted material without permission for purposes like criticism, commentary, news reporting, teaching, or research. AI companies argue that training models on copyrighted works is transformative fair use because it creates new tools rather than competing with the original works. Courts have not yet definitively ruled on this argument in the AI context.

Should I remove my content from the internet to prevent AI training?

Removing content from the internet is not practical for most creators and would eliminate the benefits of online visibility. Instead, consider using robots.txt files to block AI web crawlers, adding metadata indicating copyright status, and using services that help creators opt out of AI training datasets. Some AI companies are beginning to honor opt-out requests, though this is not yet universal.

What damages could AI companies face if they lose these lawsuits?

Copyright damages can be substantial. Under U.S. law, copyright holders can choose between actual damages (lost profits and infringer's profits) or statutory damages of $750-$30,000 per work infringed, or up to $150,000 per work for willful infringement. With some lawsuits involving thousands or millions of copyrighted works, potential damages could reach billions of dollars. However, courts have discretion in awarding damages and often consider the practical impact on innovation.

Conclusion: The Evolving Landscape of AI and Copyright in 2026

The ten AI copyright lawsuits discussed in this guide represent just the beginning of a long legal journey to define the relationship between artificial intelligence and intellectual property.
