Our antitrust litigators are aggressive, strategic and deeply knowledgeable about antitrust law. We are focused on more than simply winning a case. We pursue strategies that consider client exposure, risk reduction and recoveries and that reflect the dynamics of the market in which our clients operate.

We litigate smart which is why we have been tabbed to represent clients in high-profile antitrust cases. Our litigators possess an inside-out understanding of antitrust law, allowing us to quickly identify the weaknesses in a plaintiff’s case and craft a legal strategy to exploit those deficiencies. We also understand how high the stakes are in these cases, so our primary focus is to deliver an early-stage resolution for our clients.  more +
