O’Melveny’s reputation as a litigation powerhouse is built on a long record of delivering successful—and often groundbreaking—results in high-impact trials.

Having tried more than 70 cases to verdict over the past decade, we excel at shaping disputes for trial. From the outset of each new case, we adopt an approach that positions us to prevail in the courtroom, including framing the case to narrow disputed legal and factual issues, examining witnesses to build a compelling and credible narrative, and incorporating technology and artificial intelligence tools to streamline trial preparation.

We assemble curated cross-practice trial teams calibrated to our clients’ needs, from e-discovery specialists and lawyer-engineers to creative strategists, former prosecutors, and embedded appellate practitioners, as well as members of the American College of Trial Lawyers. Our litigation strategy is complemented by a dedicated support team of tech-savvy professionals, who offer a full palette of multimedia solutions.

No matter where the assignment is or what the substantive law may be—in state or federal court—our team has helped clients prevail in some of the country’s most closely watched legal battles in courts across the nation.

Align Technology

Obtained a favorable jury verdict defeating claims that that Align, maker of Invisalign, monopolized the market for clear aligners. Competitor ClearCorrect alleged that Align had engaged in anticompetitive conduct for years to block it and the rest of the aligner companies from competing in the market.

Aon Hewitt Investment Consulting

Won a five-day bench trial in an ERISA case, defeating claims by a class of 250,000 current and former Lowe’s employees that AON Hewitt breached its fiduciary duty to participants in Lowe’s 401(k) plans.

Amgen

In an important win for Amgen, we prevailed at trial in patent litigation over the multiple myeloma cancer drug Kyprolis®, ensuring that it would remain free from generic competition for years to come.

California Resources Corporation

Represented California Resources Corporation (CRC) in a bench trial over constitutional issues related to Monterey County Measure Z, which would have prohibited wastewater and energy companies from operating their businesses in a manner previously authorized by the State of California.

Jayson Penn

After battling the DOJ to a deadlock in two trials, an O’Melveny antitrust and white collar team prevailed in a third trial for the former Pilgrim’s Pride CEO, winning his acquittal on charges of conspiring to fix prices in the broiler chicken industry. We also won dismissal of a related securities class action that accused our client of misleading investors.
