For decades, Sheppard Mullin has been a leader in the antitrust bar. Our practice currently encompasses matters involving mergers and structural issues, criminal grand jury proceedings, international antitrust enforcement, pricing practice, product distribution, joint ventures, class actions based on federal and state antitrust and unfair competition laws, among other areas. We represent clients in a wide variety of industries, including healthcare, pharmaceuticals, financial services, aerospace, energy, technology, publishing, distribution, courier and food services.

Our Antitrust attorneys include former Antitrust Division lawyers, Assistant United States Attorneys, Federal Trade Commission lawyers, national practice leaders - including one of the leading antitrust lawyers in the United States (Chambers and Partners) and a California Antitrust Lawyer of the Year (State Bar of California) - and a former Chair of the Antitrust & Unfair Competition Section of the California State Bar. Of course, our group includes highly-credentialed native Korean speakers. We have applied our expertise on behalf of major Korean businesses, and those from other Asian countries since the 1980’s.

Government Investigations

Much of the enforcement of antitrust laws is done by government agencies, particularly the Federal Trade Commission and the Antitrust Division of the Department of Justice. In addition, the California State Attorney General and local prosecutors often use California’s Cartwright Act and Unfair Competition Law to investigate and bring enforcement actions.

Sheppard Mullin counsels Korean clients involved in government civil investigations and enforcement activities, including merger transactions, joint ventures and various types of pricing and distribution restraints. Our understanding of and direct experience with merger enforcement allows us to steer clients successfully through what can often be a difficult and complicated process. We also routinely represent our clients before the Federal Trade Commission and the Department of Justice, where we maintain a positive reputation and solid working relationships with government representatives. Our attorneys have many years of experience practicing at enforcement agencies.

As a result of experience and the results we have achieved, major Korean companies have entrusted us with their most serious and sensitive antitrust issues.

Private Civil Antitrust Litigation

Under both state and federal antitrust laws, private parties can bring antitrust claims seeking treble damages, injunctive relief and recovery of attorneys’ fees. Such lawsuits may assert a variety of antitrust violations such as price fixing, price discrimination, distribution restraints, monopolization and the like. Sheppard Mullin typically represents defendants in such actions, although we sometimes prosecute such matters.

We currently represent various defendants in many of the most significant antitrust class actions in the country. These include actions relating to vitamins, wholesale electricity, Dynamic Random Access Memory (“DRAM”) and cosmetics. In addition, we have recently defended – and prosecuted – monopolization and merger cases representing clients in industries ranging from sports to newspapers. Our attorneys have also successfully tried numerous major antitrust cases.

A very important aspect of these cases is the coordination of responses to government agencies all over the world. Korean companies regularly ask us to coordinate and lead their worldwide response to antitrust investigations.


We recognize that the best way to avoid issues with international regulators is to implement strong compliance plans. In this area, it is particularly important for us to utilize the members of our group who are Korean. They are in the best position to know how to build and communicate compliance plans to Korean executives and staff.

Entertainment, Technology and Advertising

Our entertainment lawyers have distinguished themselves with the ability to represent media companies on a global basis in multi-year television output licensing and joint venture agreements, including structuring satellite and cable platform deals for studios in Italy, Germany, France and Spain. By aiding in the creation of these programming opportunities, our lawyers are pivotal in offering studio clients both strategic and tactical guidance in international markets as well as in emerging multimedia environments. In addition, we are experienced in structuring international co-productions, both under various bi-lateral Treaties and the European Convention, with a view to maximizing the financial and creative benefits available to producers.

Our attorneys have also represented major studios, independent production companies and financiers from around the world in the development, financing, production and distribution of motion picture and television content, including successful and lucrative syndicated television series. We also advise in connection with the exploitation of ancillary and subsidiary rights, such as merchandising, in markets around the world.

Our banking and finance group focuses on experience and efficiency. Having a strong knowledge of bankruptcy and workout issues also allows us to better protect our clients at the front end. Our lender clients include major banks and financial institutions located in the United States, the Republic of Korea, and other countries, together with insurance companies, lessors, venture capital groups, and investors, and our borrower clients include businesses of all types, ranging from large publicly traded companies to small privately held businesses.

Insolvency and Financial Restructuring

In the area of insolvency, we represent clients in multiple jurisdictions in such industries as: financial services, infrastructure, sports, retail, energy, consumer products, telecommunications, professional service firms, heavy industry, and media and entertainment. Specifically, our attorneys represent note holders, ad hoc note holder committees, indenture trustees, financial institutions and opportunistic investors in cross border and multijurisdiction restructurings, creditors rights litigations and liquidations of collateral for defaulted note issuances, bank loans and other claims involving emerging, developing and developed market issuers and debtors in Asia, Australia, Eastern Europe, Europe, Latin America and South America. We have extensive experience on crossborder matters involving China and Asia. These representations often involve consensual restructurings, multiple and ancillary insolvency proceedings in various jurisdictions, chapter 15 proceedings, litigations and appeals in the U.S. and other jurisdictions, and arbitration proceedings to enforce the client’s rights in various jurisdictions.

We also represent buyers of distressed assets in multiple jurisdictions, especially in developing and emerging markets. We effectuate these acquisitions through an in-depth knowledge of many jurisdictions’ legal regimes and often with the use of experienced and trusted local counsel.

Intellectual Property

The firm advises its international clients on patents, trademarks, copyrights, trade secrets and false advertising. We routinely secure and enforce intellectual property rights both domestically and abroad. We create optimal structures for transactions and negotiations involving intellectual property, and assist our clients with practical concerns related to e-commerce and data retention.

We not only represent clients before government tribunals, we also represent governments, for example, the German Federal Ministry of Justice and the Government of the French Republic in the Google book scanning case.

Internal Investigation and FCPA

Our lawyers advise both U.S. and international businesses and their agents on the variety of U.S. laws that govern commerce to and from the United States, including the Foreign Corrupt Practices Act ("FCPA"). The FCPA makes it illegal for commercial enterprises or individuals representing such entities to offer, promise to pay, or direct or authorize another individual to pay money or anything of value to a foreign government official for the purpose of expanding or maintaining their commercial interests. Enacted in 1977 and enforced with increased fervor in recent years, the FCPA is aimed at prohibiting bribery, including suspicious political contributions. We conduct internal investigations to detect and remedy problems before they cause more damage. We also advise clients on the full range of issues implicated by the FCPA and related anti-corruption statutes around the world. 

Labor and Employment

Labor and employment laws affect the entire legal relationship between employers and employees, beginning with the initial hiring process and expanding into every facet of daily operations, including job descriptions, wages, promotions, reviews, terminations, benefits, mergers and acquisitions, as well as the successful resolution of disputes pertaining to unfair labor practices and discrimination. Because the laws that apply to the labor and employment relationship are found at all levels—federal, state, county and even city—making sense of these often conflicting requirements is more of a challenge than ever for employers.

On many occasions, employers seek to “do the right thing” and yet do not realize they might be in violation of the law. Knowing what to do and when is a core competency of our Labor and Employment attorneys. With one of the largest Labor and Employment practices in the U.S., Sheppard Mullin advises employers in all aspects of employment counseling and litigation. The strength and depth of our practice is rooted in our ability to provide truly full service labor and employment law counseling. Many of our multinational clients view our Labor and Employment practice as an extension of their in-house legal department, while our emerging and middle market clients rely upon the true depth of our expertise and the responsive service we are able to provide daily.

Privacy and Data Security

Our Privacy and Data Security Team helps businesses unlock the value of data, while ensuring compliance with U.S. and non-U.S. laws and standards that regulate the collection, use, sharing and protection of data. We counsel clients on cross-border data transfers, including compliance with EU, Canadian and other international data privacy laws. We routinely handle US-EU Privacy Safe Harbor and US-Swiss Privacy Safe Harbor certifications for clients. We represent clients in transactions that involve cross border data transfers, including under EU standard contractual clauses for the transfer of personal data. Our expertise covers customer data, employee data and credit cardholder data. With offices in Seoul, Shanghai, Beijing, London and Brussels, we have local expertise with respect to privacy and data security concerns involving the Korea, China, UK and the EU.

Tax, Estate Planning and Immigration

An intercontinental family with members scattered throughout the world, a foreign executive contemplating a transfer to the U.S. and a foreign investor with assets in the U.S. must exercise caution as to how their holdings are structured. Prudent estate and tax planning will result in significant tax savings for several generations.
