Investigations and litigation involving monopolization and monopoly maintenance continue to be a focus for competition authorities and private plaintiffs. These cases often turn on complex liability theories and require precise economic evidence to evaluate alleged exclusionary conduct.

We work with both government enforcement agencies and private companies in matters involving monopolization and the maintenance of monopoly power. Our team supports clients throughout the life cycle of a case, from initial investigations to trial, providing independent economic analysis and expert testimony.

We have significant experience addressing a wide range of alleged conduct involving both single-firm and multi-firm behavior. These include exclusive dealing, all-units and bundled discounts, hub-and-spoke arrangements, vertical foreclosure, and monopoly leveraging. Our professionals have contributed expert analysis in some of the most significant monopolization cases litigated in recent years.

Common challenges in monopolization and monopoly maintenance cases include:

  • Investigations into exclusionary practices by dominant firms
  • Allegations involving exclusive, bundled, or loyalty-based pricing strategies
  • Accusations of coordination between firms through vertical relationships
  • Claims of foreclosure or leveraging across markets or supply chains
  • Responding to liability theories involving both vertical and horizontal conduct
