Mass Torts

Mass Tort Lawyers — Dangerous Drugs, Defective Devices & Toxic Exposure

When Corporations Cut Corners, People Get Hurt.

Trial Lawyers United represents individuals nationwide harmed by dangerous drugs, defective medical devices, toxic exposures, and unsafe consumer products. We organize strength in numbers to hold corporations accountable.

We understand that when corporations put profits over people, the consequences can devastate lives. Mass torts are complex, usually involving thousands of individuals harmed by dangerous drugs, defective products, environmental disasters, or corporate and institutional negligence. These cases require more than legal knowledge, they demand strategy, resources, and experience at the highest level. With over 100 years of combined years as successful trial lawyers, our lawyers have represented injured people throughout the country to obtain the compensation and justice they deserve.

What Qualifies as a Mass Tort

Mass torts arise when a single product, substance, or corporate practice injures many people in similar ways. Unlike class actions — which resolve claims collectively — mass torts preserve each client’s individual claim while consolidating common discovery and pretrial proceedings for efficiency.

Mass tort litigation typically involves one or more of the following categories:

• Dangerous Pharmaceuticals: Prescription or over-the-counter drugs linked to serious injuries that were not adequately disclosed to patients or physicians
• Defective Medical Devices: Implants, catheters, surgical systems, and hardware that fail inside the body due to design or manufacturing defects
• Toxic and Environmental Exposures: Chemicals contaminating water, air, soil, or workplaces — including industrial operations, waste disposal, firefighting foams (AFFF/PFAS), and military base contamination
• Unsafe Consumer Products: Everyday products that cause systemic harm due to contamination, poor design, or inadequate warnings — including baby food, contamination in infant formula, hazardous substances in personal care products, and talc-based hygiene products
• AI and Technology-Related Harm: Digital products and AI platforms that cause measurable psychological or physical harm to users, particularly minors

How Mass Tort Liability Works

We pursue claims against every entity in the chain responsible for the hazard and its concealment. Legal theories include:

Defective Design

The product was unreasonably dangerous as designed, and a safer alternative was feasible.

Manufacturing Defect

The product deviated from its intended design during production, creating a hazard not present in the original specifications.

Failure to Warn

The manufacturer knew or should have known of risks and failed to provide adequate warnings to consumers, physicians, or regulators.

Negligence

The manufacturer failed to exercise reasonable care in designing, testing, manufacturing, or marketing the product.

Breach of Warranty and Consumer Protection

The product failed to meet express or implied representations of safety, or the company violated state consumer protection statutes.

Evidence and Causation in Mass Tort Cases

Proving a mass tort claim requires connecting corporate conduct to individual injury through multiple evidence categories:

• Product design files, internal safety assessments, and adverse event data
• Regulatory submissions and correspondence with the FDA, EPA, or other agencies
• Medical records, diagnostic imaging, and pathology establishing the injury and its timing
• Independent scientific testing, epidemiology, and toxicology demonstrating the mechanism of harm
• Expert testimony connecting corporate knowledge to preventable injuries
• Chat logs, usage data, and platform design documents in technology-related cases

Our attorneys work with toxicologists, epidemiologists, oncologists, engineers, psychologists, and other specialists to build each case from the science up.

Common Injuries in Mass Tort Cases

• Organ damage and systemic toxicity
• Cancers linked to chemical, hormonal, or environmental pathways
• Device failure leading to revision surgeries, infections, emboli, or vascular injury
• Neurologic, reproductive, and endocrine complications
• Psychological harm, addiction, and self-injury (in AI and technology cases)
• Wrongful death and survivorship claims

How the Mass Tort Process Works

1. Free Intake and Screening

We review your exposure history, prescriptions, devices, product use, timeline, and symptoms to determine whether you may have a viable claim.

2. Medical and Evidence Collection

Our team orders and analyzes medical records, imaging, implant identification, pharmacy data, product purchase history, and — where applicable — digital usage records.

3. Case Building and Filing

We draft pleadings tailored to the applicable venue and join coordinated proceedings — whether federal multidistrict litigation (MDL), state-coordinated actions (JCCP), or individual lawsuits.

4. Common Discovery and Bellwethers

We contribute to document review, depositions, expert development, and bellwether trial preparation within the coordinated proceeding.

5. Resolution

We evaluate settlement matrices, lien obligations, and allocation frameworks to maximize your net recovery. If a fair resolution is not offered, we are prepared to try the case.

Every case is handled on a contingency fee basis. You pay nothing unless we recover compensation for you.

Frequently Asked Questions

What is a mass tort?

A coordinated set of individual injury cases involving the same product, substance, or corporate conduct. Each client maintains an individual claim, but common legal and factual issues are litigated together to streamline discovery and reduce costs.

How is a mass tort different from a class action?

In a class action, one or a few named plaintiffs represent an entire class, and the resolution applies to everyone. In a mass tort, each plaintiff has an individual case with individual damages. Your case is evaluated on its own facts, not averaged with others.

How long will my case take?

Timelines vary significantly by docket, scientific complexity, and venue. Some mass torts resolve within 3-5 years; others take longer. We keep clients informed throughout discovery, bellwether proceedings, and settlement programs.
What will this cost me?

Nothing upfront. We advance all case costs and work on a contingency fee basis. You pay no fee unless we recover compensation for you.

Can I still file if I used more than one product?

Yes. Many clients have multiple exposures or used several products over time. We map the full timeline and pursue claims against all responsible parties.
