About David Ko — Over 20 years of Washington class action experience

He has significant trial experience, having tried months-long trials in both federal and state court.

David has been at the center of the firm’s largest and most high-profile cases. He represents government entities all over the country in In re National Prescription Opiate Litigation, MDL 2804 (N.D. Ohio) -seeking to hold manufacturers, distributors, and dispensers responsible for creating and fueling the opioid epidemic-which has resulted in over $50 billion in settlements to date. He was also one of the primary attorneys in In re Facebook, Inc. Consumer Privacy User Profile Litigation, MDL 2843 (N.D. Cal.), a class action alleging Facebook discloses user information and data without consent that recently resolved for $725 million, the largest settlement to date of a U.S. privacy class action and the most Facebook has ever paid to resolve private litigation. David also helped lead the firm’s efforts in In re JUUL Labs, Inc. Marketing, Sales Practices, & Products Liability Litigation , MDL 2913 (N.D. Cal.), which resulted in nearly $2 billion in settlements from JUUL and Altria for their role in the youth vaping epidemic.

David served in a variety of prominent positions and committees in these MDLs, and continues to serve in leadership roles in complex MDLs against the pharmaceutical industry including against Pharmacy Benefit Managers. He currently serves as Co-Lead Counsel on behalf of a class of independent pharmacies in In re GoodRx and Pharmacy Benefit Manager Antitrust Litigation (No. II), MDL 3148 (D.R.I.), and on the Plaintiffs’ Executive Committee on behalf of self-funded plans in In re Insulin Pricing Litigation, MDL 3080 (D.N.J.).

Prior to joining the firm, David clerked for the Honorable Ricardo S. Martinez, U.S. District Judge in the Western District of Washington. He is past President of the Korean American Bar Association of Washington, and a fellow of the Washington Leadership Institute. While born in Seoul and extremely proud of his Korean heritage, David has spent most of his life in the Seattle area, where he currently lives with his wife and two young daughters and is an avid supporter of all Seattle sports teams.
