“[R]eigns as an international powerhouse, servicing both the most established and the fastest emerging business centers of the world.” Benchmark Litigation, 2019

Cleary Gottlieb Steen & Hamilton LLP has been a leader in the legal profession for more than 70 years. Our 1,300 lawyers, who operate in 16 offices in major global financial centers, work together across practices, industries, and jurisdictions to provide clients with clear, actionable approaches to their most complex legal and business challenges.


Litigation and Arbitration at Cleary 

Recognized as one of the top litigation and arbitration groups in the world, Cleary has counseled corporations, financial institutions, governments, and individuals in cases that have dominated the business and legal news. Our engagements frequently require cross-border coordination of the firm’s varied resources, allowing us to pair our corporate, regulatory, and financial experience with our litigation prowess.

Our U.S. team has a wealth of government experience, including 11 former federal prosecutors (including two former U.S. Attorneys from the Southern District of New York); several former senior officials of the SEC, including its most recent Chief Litigation Counsel of the Enforcement Division and a former General Counsel; and several former senior officials from the FTC and the DOJ’s Antitrust Division, including the Division’s most recent Deputy Assistant Attorney General for Litigation.


Antitrust Litigation

For decades, we have represented many of the largest U.S. and international companies in the full range of antitrust litigation, including monopolization, conspiracy, and merger cases in district and appellate courts across the United States. Unlike at many other firms, where generalist litigators handle competition cases, our antitrust litigators are true antitrust practitioners, and this difference is demonstrated in our track record of success. Notable clients include 21st Century Fox, BNP Paribas, EquiLend, Goldman Sachs, HSBC, “K” Line America, Keurig Green Mountain, NSK, NVIDIA, Sabre Holdings, Teladoc, and The Dow Chemical Company.


Bankruptcy and Workout Litigation

Harnessing our integrated global partnership and network of locally qualified lawyers, we represent both debtors and creditors in cross-border restructurings and insolvency proceedings in the United States, Latin America, Europe, the Middle East, and Asia. Notable clients include BNP Paribas, BNY Mellon, Citigroup, Crédit Agricole, ESL Investments, Geoffrey LLC, Goldman Sachs, HSBC, J. Aron & Company, Nortel Networks Inc., Oi, Punjab National Bank, Texas Pacific Group, and Warburg Pincus.


Complex Civil Litigation

Cleary is recognized as a leading firm for complex commercial disputes, bringing business savvy and an international point of view to bear on a full range of business matters. Notable clients include Assured Guaranty, Bank of America, BNP Paribas, Citigroup, Crédit Lyonnais S.A., Goldman Sachs, HSBC, J. Aron & Company, Lowe’s, National Amusements, Inc., National Westminster Bank plc, Robert Bosch GmbH, and Warburg Pincus.


Intellectual Property Litigation

Our formidable litigation practice includes the litigation and arbitration of IP disputes, with particular experience in international patent and trademark infringement matters, and licensing and JV disputes, in multiple jurisdictions. We have led clients to victories in many landmark IP cases. Notable clients include Medytox, Inc., Nortel Networks Inc., OpenText, Inc., United Test and Assembly Center Ltd, and Tom Ford.


International Arbitration

We have extensive experience in international commercial arbitration, investment treaty, and other arbitrations involving public international law, and in enforcing or challenging arbitral awards and foreign judgments in the United States and U.S. judgments abroad. Our lawyers also serve as arbitrators in major international cases, are experienced in drafting arbitration clauses for complex international transactions, and regularly work with our corporate colleagues on technical commercial and M&A arbitrations. Notable clients include DP World, OJSC Tatneft, Telecom Italia, Vale S.A., Vitro, and Western Digital.


Securities and M&A Litigation

We have extensive experience representing boards, special committees, acquirers, and financial advisors around the country in litigation related to mergers, tender offers, and other takeover related settings. We also advise on a range of corporate governance matters and handle other derivative litigation challenging the actions of boards of directors. Notable clients include Allergan, American Express, Bank of America Merrill Lynch, Citibank, D.B.S. Satellite Services Ltd., Goldman Sachs, Kindred Healthcare, National Amusements, Inc., OneMain Holdings, Petrobras, Ryanair, Sky Solar Holdings, Synutra International, and Trivago.


Sovereign Litigation and Arbitration

For more than 30 years, the firm has worked on litigation and arbitration matters involving sovereign states and state-owned entities in a wide range of disputes, including debt restructurings, and has developed and refined the legal and financial techniques used to address these problems. Notable clients include Japan, The Arab Republic of Egypt, The French Republic, The Hellenic Republic (Greece), The Republic of Argentina, The Republic of Austria, The Republic of Iraq, The Republic of Slovenia, and The Russian Federation.


White-Collar Defense and Internal Investigations

Cleary advises and defends the world’s leading financial institutions and multinational corporations and, in certain cases, their senior employees, in a broad range of sensitive criminal and regulatory matters. We defend clients before the DOJ, SEC, and other government agencies and—when necessary—in court, and we regularly conduct internal investigations for companies and their boards. Our established practices in the U.S., Europe, Asia, and Latin America enable us to provide a comprehensive and coordinated approach to cross-border enforcement matters. Notable clients include Alpha Natural Resources, BNDES, Citigroup, Commerzbank, Goldman Sachs, GOL Linhas Aéreas Inteligentes, HSBC, Opko Health, Inc., Petrobras, and Robert Bosch GmbH.
