A deep thinker and intuitive strategist, Amelia Sargent brings the best of academia’s rigor and curiosity to her complex commercial litigation practice, with an emphasis on trade secrets and business disputes. Benchmark Litigation has named Amelia a “Litigation Star” for 2022 and 2023 and included her on their 2021 “40 & Under Hot List.”
Amelia’s twelve years of trial and appellate experience includes stand-up roles at multiple trials, appellate briefing and argument before the Ninth Circuit, and three Supreme Court amicus briefs.

In the prior phase and trial, Amelia questioned or defended five witnesses, including cross-examining both key executive corporate witnesses, resulting in a liability ruling for the client.
- As lead counsel defending nine executives and employees in arbitration, Amelia leveraged her e-discovery and forensic expertise against a “Biglaw giant” to successfully resolve allegations of trade secret misappropriation and related torts involving the formation of a new start-up after her clients resigned from a competitor company.
- Briefed, argued, and won simultaneous motions for summary judgment, and a subsequent Ninth Circuit appeal, on behalf of a Korean LED manufacturer, winning $1m+ and defeating $16 million in cross-claims brought by a reseller.
- Drafted an amicus curiae brief on behalf of university professors on international comity issues before the United States Supreme Court in Republic of Hungary v. Simon (No. 18-1447) and Federal Republic of Germany v. Philipp (No. 19-351).
