Defending innovation in worldwide product liability challenges

We serve as the go-to defense for the world’s leading life sciences, industrial, technology, and retail companies in their complex product liability and mass tort issues. We view ourselves as “closers” of mass tort litigation. We have an unparalleled track record of using cutting-edge scientific and legal strategies to identify dispositive issues that can bring litigation to an early end, a feat we have achieved more than any other firm. Impressively, of the mass torts granted summary judgment or otherwise dismissed on dispositive motions in the last decade, DLA Piper served as lead counsel in the vast majority.

As organizations innovate by offering enhanced products to an increasingly competitive global marketplace, complex product safety standards and heightened environmental awareness pose significant challenges to our client’s invaluable advancements. Our strategic approach to resolving claims in multi-jurisdiction litigation goes beyond traditional litigation methods. As noted by Chambers USA, our team consists of “true nationally recognized experts in product liability” with “excellent strategic judgment.” Law360 has recognized our “knack for breaking down difficult science" and praised our “creativity and unorthodox tactics.”

Often serving as national, global, or settlement counsel, we have revolutionized mass tort defense through our strategic efficiency in bringing complex litigations to early, definitive conclusions. This efficiency stems from our longstanding experience adverse to major plaintiffs' firms, our proven ability to navigate multi-jurisdictional litigation involving dozens of plaintiff firms simultaneously, and our embrace of innovation, such as developing AI-enabled tools to facilitate case management and resolution. If trial is inevitable, our team of first-chair trial attorneys has experience defending our clients’ interests in jury and bench trials in some of the most challenging jurisdictions across the globe.

We partner with clients to safeguard their investment and most innovative products through our team’s exceptional combination of scientific rigor and strategic efficiency. Leveraging our team of litigators — which includes medical doctors and others who hold PhDs and advanced scientific and technical degrees — in combination with former regulators and in-house counsel, we build strategies that stick, challenge flawed methodologies with precision, and explain complex medical issues in a way that moves juries and persuades judges.

DLA Piper has a deep bench that allows them to provide everything a company needs in a bet-the-company type product liability suit. Few can match their team.

As Chambers has noted, we are “brilliant at working with anything scientific,” with an unmatched understanding of the complex scientific issues. The Legal 500 likewise observes that we combine strategists, appellate experts, and "an army of MD/JDs and PhD/JDs" to advise on technical aspects.

Our global platform empowers us to assist clients in navigating foundational changes under the new European Union Product Liability Directive—such as expanded definitions (software, AI, refurbished goods), reversed burdens of proof, recognition of psychological and data-related damages, and extended limitation periods.

Recognized by clients for keeping “the big picture in mind,” “terrific management of a mass tort,” and “fantastic job in global strategy for cross-country litigation,” we partner with clients to deliver their business’ objective.
