Pioneers in worldwide product liability compliance and defense

We help some of the world’s largest companies with their complex product liability issues. Our advice and litigation strategy are grounded in a multi-disciplinary, multi-jurisdictional approach. Whether entering new markets or general compliance advice or if you are facing mass tort, personal injury, consumer fraud, toxic tort or securities claims, or government inquiries, we help you to address the toughest challenges.

New product safety standards coupled with accelerating multijurisdictional litigation, including multidistrict litigation (MDL) in the US, and a greater focus on environmental issues have resulted in an increase of product liability class actions around the world.

We are positioned to defend claims of any size involving any industry around the globe. We advise on the legal issues associated with risk, compliance, and business management at every stage of the product development and supply chain lifecycle. We ensure you remain ahead of the curve when it comes to compliance with product safety legislation.

Our innovative approach to resolving claims goes beyond traditional litigation methods: we drive success through early actions in ways that protect our clients and strengthen the law. We serve as national and global pre-emption and resolution counsel to achieve groundbreaking legal victories, consistently resolve claims, and bring mass torts to an early end.

“Their strength is that they work as a team, you don't have individuals going out and trying to outshine others. They know their strengths and bring people in for all areas of mass torts, from science experts to coordinators”

Chambers 2021

Our lawyers have experience in the areas most likely to be of concern to manufacturers, distributors and suppliers. We’ve worked on materials restriction regulation, such as the REACH and RoHS legislation and waste and product life-cycle management legislation, such as EU legislation relating to WEEE and packaging waste. This can be broken down into three fields: bringing a product to market, products already in the market and product recalls. We advise extensively on all.

Our litigators include medical doctors and others who hold PhDs and advanced scientific and technical degrees. We use Daubert strategies in the US and leverage science-based arguments to attack claims and mitigate exposure. We translate complex information into compelling talking points that persuade opposing counsel and multi-jurisdictional judges and juries to agree with our position. Our relationships with the right expert witnesses result in a distinct advantage for your company.

Chambers and the Legal 500 rank us among the most highly regarded product liability lawyers in the world. We remain ever mindful of your company’s reputation when navigating you through product recalls, governmental investigations, insurance coverage and environmental concerns.
