Mass Tort Litigation Trends in 2025

Mass tort litigation continues to be a dominant force in the legal industry, with several high-profile cases expected to gain momentum this year.

PFAS Litigation: Addressing Widespread Contamination

Per- and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals,” have been linked to severe health risks, leading to a surge in lawsuits against manufacturers and industries responsible for contamination. In 2025:

• Thousands of cases are being consolidated into multidistrict litigation (MDL), targeting companies that produce PFAS-laden consumer products.
• Environmental impact lawsuits are increasing, with plaintiffs arguing that PFAS contamination has led to widespread water pollution and adverse health effects.
• Regulatory actions and settlements may drive corporate accountability, with companies facing potential billion-dollar payouts.

Social Media and Teen Mental Health Lawsuits

Social media giants are under fire for their alleged role in exacerbating mental health crises among teenagers. Lawsuits against companies like Meta, TikTok, and Snapchat claim:

• Algorithms are designed to increase engagement at the cost of mental well-being, leading to addiction-like behaviors.
• Companies failed to implement adequate safeguards to prevent harmful content from reaching vulnerable users.
• Parents and advocacy groups are pushing for stricter regulations, with courts expected to establish new legal standards for tech accountability.

Bayer’s Roundup Litigation: The Battle Continues

Bayer remains entangled in ongoing litigation over its herbicide Roundup, which contains glyphosate, a chemical linked to cancer risks. Despite previous settlements:

• New lawsuits continue to emerge as more plaintiffs claim exposure-related health issues.
• Scientific disputes regarding glyphosate’s safety may influence future rulings.
• Bayer’s legal strategy will likely involve appealing past verdicts while negotiating settlements to limit financial exposure.

AI and Copyright Lawsuits: The Fair Use Debate

Artificial intelligence is revolutionizing industries, but it has also sparked fierce legal battles over copyright infringement. Tech companies utilizing AI to train models on copyrighted material are facing significant lawsuits, raising fundamental questions about intellectual property rights.

Key Issues in AI Copyright Disputes

The central question in these lawsuits is whether AI’s use of copyrighted content constitutes “fair use” or unauthorized exploitation. Major concerns include:

• Training Data Transparency: Plaintiffs argue that AI firms have used copyrighted texts, images, and music without proper licensing or attribution.
• Creative Ownership and Compensation: Artists and content creators seek legal frameworks to ensure compensation when their works contribute to AI-generated outputs.
• Impact on Innovation: A ruling against AI firms could reshape how machine learning models are trained and restrict the development of generative AI technologies.

High-Profile AI Copyright Cases to Watch

1. Tech Giants vs. Content Creators: Lawsuits have been filed against companies like OpenAI, Google, and Microsoft for allegedly training AI models using copyrighted materials from books, news articles, and visual art.
2. Music Industry Crackdowns: Record labels are pushing back against AI-generated music that mimics copyrighted songs and artists’ voices.
3. Legislative Developments: Lawmakers worldwide are considering new regulations to define AI’s role in copyright law, aiming to balance innovation with content protection.

Implications for the Legal Industry

• Mass tort litigation is expanding into new areas, particularly environmental contamination and digital harms, setting legal precedents for corporate responsibility.
• AI copyright lawsuits will influence the future of artificial intelligence and content creation, with courts determining how intellectual property rights apply to machine learning.
• Legal professionals must stay informed on evolving case law, as outcomes in these high-profile cases will shape corporate strategies, regulatory frameworks, and individual rights.
