Derek T. Ho litigates high-stakes commercial cases with often billions of dollars at stake.  He has helped clients obtain billions of dollars through trial or settlement.  As both an experienced trial litigator and a seasoned appellate lawyer, Derek represents plaintiffs and defendants in all phases of litigation.

Derek also has extensive experience representing litigation finance firms, having represented major players in that industry since its inception.  His successful representations include seminal cases establishing the legality of litigation funding arrangements and the protection of litigation funding agreements and communications from discovery.  

Derek has served as lead appellate counsel in cases in nine federal circuits, as well as in several state appellate courts.  He has been the principal drafter of more than 25 merits and amicus briefs in the U.S. Supreme Court.

Derek maintains an active pro bono practice focused on civil rights litigation.  He serves on the Board of Trustees of The Roxbury Latin School and on the Board of Directors of the Lawyers’ Committee on Civil Rights Under Law and the American Constitution Society.
