About

Provided by Katten

Katten's Litigation practice has earned top recognition for its track record of success. We believe our litigation victories must provide value and long-term benefit to our clients. Katten attorneys have the depth and experience to handle, and if necessary, to litigate through appeal, virtually any type of case. We regularly try "bet the company" cases to verdict and appear in federal and state courts across the nation at the trial and appellate levels, before arbitration tribunals and administrative law judges, and in specialty courts.

Clients benefit from the experience of the many Katten attorneys who have held positions at the US Department of Justice, the US Attorney's Office, the White House, the US Securities and Exchange Commission, and other government agencies and prosecutors' offices at both the state and federal levels across the country. Our team adeptly handles the many risks, investigations, government inquiries and proceedings that accompany large cases, and guides clients through the resulting parallel and complex proceedings. We act as national or regional counsel for clients, coordinating closely with local and other outside counsel to bring the best possible conclusion to complex and multiple jurisdiction actions.
