Aaron Charfoos is an accomplished privacy and data protection trial lawyer focusing on incident response, privacy litigation, and European data privacy compliance (General Data Protection Regulation [GDPR] and cross-border data transfers).

Aaron litigated his first privacy case in 2010, building on a decade of experience in patent and technology cases.

Prior to joining Jones Day he obtained two major trial victories for clients in 2012, including one of the top defense verdicts in California that year. He also has won numerous appeals before the Federal Circuit, Ninth Circuit, and Indiana Court of Appeals.
