Bates White has extensive experience working with clients on class action litigation across an array of industries and claims, including antitrust and competition, fraud and false claims, and product liability. Bates White has worked for both plaintiffs and defendants on a variety of class matters.

Our experts provide economic analysis, expert testimony, and litigation support, at all phases from class certification to merits to trial. We also support mediation and settlement negotiations. Using advanced analytics, rigorous statistical approaches, and economic models, our experts provide liability, causation, and impact analyses; estimation of class-wide and individual impacts; and settlement and allocation analyses.

We are recognized for providing expert opinions that are empirically sound and that accurately support the presence or absence of common impact across putative class members based on case-specific evidence. Court rulings have validated the analyses and conclusions of our experts in numerous cases.
