Class actions pose exceptional challenges and threaten extraordinary liabilities. Few firms can match our experience in defending such cases. In the past five years alone, we have defended nearly 200 class actions asserting privacy, consumer protection, wage and hour, antitrust and other claims. We have also been at the forefront of the fight against class action abuses by testifying to legislatures, pioneering removal strategies, designing and defending dispute-resolution programs and challenging misuses of the class action device. Fortune 100 companies across industries have trusted us to protect their businesses, budgets and brands from the most complex cases brought by the most aggressive adversaries in the most hostile courts. In short, when business leaders have needed thought leaders, they have called on us.

Class Actions


Drinker Biddle's antitrust litigators have played a role in some of the most complex and high-profile class action cases in courts throughout the country such as In re Baby Food Antitrust Litigation, In re Linerboard, In re Pharmacy Benefit Managers Antitrust Litigation, In re Oriented Strand Board, Dentsply Antitrust Litigation and In re Blood Reagents Antitrust Litigation.


We are a leader in consumer class action defense work and often achieve quick, favorable resolutions and have a strong record of defeating class certification. We defend against consumer class actions involving consumer fraud, advertising, antitrust, pricing, excessive fees, marketing, telemarketing, labeling, product defects, privacy, truth in lending, warranties, and allegations of failure to disclose or fraudulent business practices and off-label promotion.

Labor & Employment

Our lawyers have extensive experience representing employers in employment class action litigation, including:

  • Class actions challenging hiring, promotion, compensation and other employer policies and practices on the basis of race, sex, age, national origin and other legally protected characteristics.
  • Government initiated class actions by the OFCCP against federal contractors and subcontractors and by the state and federal labor departments.
  • State and federal wage and hour collective and class actions challenging exempt job classifications, meal and rest breaks, travel, on-call and waiting time and other pay practices.
  • ERISA and related employee benefits class actions.

Products Liability

Drinker Biddle’s reputation as one of the top class action defense firms in the country results from its experience in defending against alleged class actions across a broad range of products litigation.

Defense against punitive damages claims has also come to play a critical role in mass tort and products litigation. We have substantial and successful experience in building the factual and legal foundations on which to counter such claims. We have similar experience in developing a record and molding the arguments with regard to Daubert motions.


Drinker Biddle represents public registrants, underwriters, directors, officers, and accountants in shareholder and securities fraud class actions. We have represented a Big Four accounting firm in several securities fraud class actions, including the PNC Securities Litigation in the Western District of Pennsylvania and the IKON Office Solutions Securities Litigation in the Eastern District of Pennsylvania and the United States Court of Appeals for the Third Circuit.
