Ariel N. Lavinbuk is a trial and appellate litigator.  He has a broad commercial practice, with substantial experience in matters involving debtor-creditor and fraudulent-transfer law, and intellectual property licensing and litigation. Ariel has particular expertise litigating international disputes in U.S. courts and frequently works with and coordinates foreign counsel prosecuting actions abroad.

Debtor-creditor and fraudulent-transfer law.  In recent years, Ariel has represented individual creditors, their trustees, ad hoc groups, and creditors’ committees in disputes arising out of a number of major restructurings and bankruptcies, including those of Caesars Entertainment Operating Company; Nortel Networks Inc.; the Tribune Company; OAS S.A. (Brazil); Energy Future Holdings Co.; Education Management Corp; Argentina; Puerto Rico; Intelsat; Arch Coal; Petrobras (Brazil); Patriot Coal Co.; DTek Finance (Ukraine); Fannie Mae and Freddie Mac; Tousa, Inc.; and Residential Capital, LLC.

Intellectual property licensing and litigation.  Ariel has deep knowledge of the Copyright Act and regularly represents and advises clients in litigation and negotiations involving trade secrets, patents, and confidential and proprietary information.  As lead counsel, he has successfully negotiated deals concerning the ownership and funding of technology start-ups and he regularly advises website and application developers on Terms of Use, data privacy, and other compliance-related issues.

Ariel has argued or briefed cases in federal and state trial courts nationwide, in bankruptcy courts, and in nearly every federal court of appeals. His Supreme Court experience includes petition and merits-stage briefing in nearly twenty cases—among them, Costco v. Omega (2010), and Kirtsaeng v. John Wiley & Sons (2013), in which his work helped persuade the Court to permit, over the United States’ objection, the importation of copyrighted gray-market goods. Ariel also counsels clients on matters related to government ethics, holds a Top Secret/SCI security clearance, and has represented foreign and U.S. elected officials, their staff, and lobbyists in civil and criminal actions and congressional investigations.

Ariel began his career at McKinsey & Co., where he advised technology and media companies on a wide variety of strategic and organizational issues. He also spent time on the management staff of Teach For America, where he placed nearly 2,000 teachers in over twenty school districts nationwide and disbursed millions of dollars in financial aid.

Ariel clerked for Judge Stephen F. Williams on the United States Court of Appeals for the D.C. Circuit.  He is widely published, with works appearing in the Harvard Law Review, the Yale Law Journal, and Slate, among other publications.  He is also a fellow and founding board member of the Truman National Security Project, and is a frequent panelist at Georgetown Law School’s Supreme Court Institute.
