His trial experience spans federal and state court, and he has trial experience bringing and defending against claims on behalf of his clients. Patrick brings passion, insightfulness, and a methodological approach to trial, helping clients achieve their goals as efficiently and effectively as possible. When not trying cases, Patrick draws on his trial experience to help his clients in litigation and enforcement matters focus on key objectives and how best to achieve those objectives. Representative litigation matters span antitrust, racketeering, breaches of fiduciary duty, securities fraud, to other commercial and business litigation claims.

Before joining King & Spalding, Patrick served as an Assistant U.S. Attorney in the United States Attorney’s Office for the Northern District of Illinois.
