Our seasoned attorneys provide comprehensive legal services to address the multifaceted challenges that businesses face in today’s competitive environment, including:
- Private Antitrust Litigation and Class Actions. We regularly represent clients in high-stakes antitrust litigation in both federal and state courts where the risks of treble damages are acute. These complex cases include class actions, simultaneous parallel litigation, and cases with related criminal investigations, which require special experience, coordination and capabilities. We handle cases under the Sherman Act, Clayton Act, Robinson-Patman Act, and state equivalents, including actual and attempted conspiracy and monopolization claims. We get cases like these dismissed for our clients, and we then defend those dismissals on appeal and have set important antitrust precedent in federal appellate courts for our clients.

We develop robust defense strategies for Fortune 500 companies, international corporations, and their executives and directors facing criminal charges or investigations by the DOJ or other government agencies. We draw upon the experience of former high-ranking federal prosecutors and DOJ leadership in grand jury proceedings and high-stakes cases involving alleged price fixing, bid rigging, market allocation, and more.

We are valued business advisors for our clients, helping them achieve their business objectives while complying with both U.S. and international competition laws. We proactively manage risk by helping develop and implement effective compliance and training programs. We also conduct antitrust risk assessments and offer guidance on mergers and acquisitions, joint ventures, and other business practices relating to pricing, distribution, exclusive dealing, market share, expansion, licenses, mergers, trade associations, standard setting organizations, and more. We compliment this counseling with substantial experience conducting complex internal investigations of alleged wrongdoing and crafting remediation strategies where necessary.

We assist clients with investigations, prosecutions, and private treble damage litigation involving global cartels, and we advise clients on compliance with antitrust laws across multiple jurisdictions. We coordinate with legal teams worldwide, manage the intricacies of cross-border legal issues, and defend against allegations of international price-fixing and market-sharing schemes.
