In high-stakes litigation, every move counts. From the initial positioning of the facts and issues, to trial of the case, to disposition of the appeal, smart moves make the difference between a favorable resolution and a costly judgment.

At O’Melveny, significant, bet-the-company cases are a specialty. In the past four years alone, we have helped our clients bring nearly 30 cases to verdict. In state court and federal court and on appeal, from California to New York and in between—our award-winning team has helped clients prevail in some of the country’s most closely watched legal battles.

Although most large firms can litigate a case, few excel at shaping a dispute for trial. No matter where the assignment is or what substantive law is at issue, we draw on every available resource to put the best team on the field. Through cross-practice and cross-border collaboration, our trial lawyers can and do cover any area of law, in any jurisdiction.

At every stage of the litigation process, we help clients make the right moves.
