Ariel N. Lavinbuk is a seasoned trial and appellate litigator who has taken dozens of complex cases to resolution in federal and state trial courts nationwide, in bankruptcy courts, and in nearly every federal court of appeals. His U.S. Supreme Court experience includes merits-stage briefing in 10 cases and petition-stage briefing in many more.

A significant portion of Ariel’s work is devoted to complex commercial and investment-related disputes involving loan and bond instruments, fraudulent transfers and preferences, the fiduciary duties of officers and directors, commercial fraud, and civil RICO. He also has substantial experience litigating intellectual property disputes — particularly breach of contract, trade secret and copyright claims — at every level, from jury trials to the U.S. Supreme Court.

Ariel regularly handles complex, sensitive cross-border matters — particularly in the investment and intellectual property contexts. He often litigates international disputes (including against foreign sovereigns) in U.S. courts, frequently works with and coordinates foreign counsel prosecuting actions abroad, and has provided expert testimony on U.S. law in foreign judicial proceedings. He has also represented foreign and U.S. elected officials and their staff as well as senior executive branch officials in civil and criminal actions and congressional investigations.

Ariel began his career at McKinsey & Co., where he advised technology and media companies, as well as the U.S. government and the World Bank, on a wide variety of strategic and organizational issues. He also spent time on the management staff of Teach For America.
