Firm Overview:
Williams & Connolly LLP is a unique institution whose distinctive history and culture combine to create a partnership of mainly trial lawyers with an incredible breadth of experience. Located in one office in Washington, DC with approximately 275 partners and associates, nearly all of whom are devoted to litigation, the firm’s reputation as one of the nation’s premier litigation firms vastly exceeds its size. The firm’s experience is not confined by geography or industry. It handles high-stakes litigation and investigations that span not just the country, but the globe and its cases involve every major industry. It has represented most of America’s largest corporations, all of the biggest accounting firms, more than 100 of the biggest law firms, the largest banks and the largest media organizations in the world. And, it has represented the last three Presidents of the United States, several Vice Presidents and many Cabinet Officers, Senators and Congresspersons. The diversity of the firm’s practice spans criminal, Supreme Court, securities, patent and product liability litigation, among several other practice areas.

Main Areas of Practice:  

Civil Litigation & Trial Practice: Williams & Connolly has a reputation for aggressive pursuit of its clients’ interests. Clients frequently retain the firm for “bet-the-company” litigation. Williams & Connolly has handled virtually every kind of litigation imaginable, for individuals and institutions, in cases ranging from breach of contract actions involving hundreds of millions of dollars to the defense of major consumer class actions. The firm handles the most complex cases facing businesses in any industry, with a particular emphasis on preparing and taking cases to trial.

Criminal Defense & Government Investigations: Williams & Connolly was one of the first major law firms in the United States with a significant criminal defense practice and has retained its position as one of the premier white collar defense law firms in the world. It has represented individuals, public and private corporations and other entities in government and internal investigations, trials and appeals throughout the United States and abroad. Its work has spanned a wide array of subject matters, including securities and financial fraud, insider trading, antitrust, healthcare fraud, environmental, tax, False Claims Act, qui tam, Foreign Corrupt Practices Act, public corruption and export controls, among other areas. Williams & Connolly lawyers have experience dealing with diverse investigating authorities, including US Attorneys’ Offices throughout the United States, all sections of the Department of Justice—including Public Integrity, Antitrust and Fraud—investigative committees of the US Congress, the Securities and Exchange Commission, the Commodity Futures Trading Commission, various Inspectors General and state attorneys general, among others.

Supreme Court & Appellate: Williams & Connolly lawyers regularly represent clients before the Supreme Court of the United States and have argued some of the highest-profile criminal cases decided by the Court in the last few years. For instance, the firm presented oral argument in Maryland v. King, the landmark case on the constitutionality of DNA testing of arrestees that one justice described as “perhaps the most important criminal procedure case that this Court has heard in decades”; Bailey v. United States, which involved the authority of the police to detain an individual incident to the execution of a search warrant after the individual has left the scene; and Merck v. Reynolds, which concerned the statute of limitations for private securities-fraud actions. Williams & Connolly lawyers also appear regularly in federal and state appellate courts across the nation. The firm’s appellate experience spans all areas of its litigation practice, with notable recent victories in the areas of antitrust, criminal, patent, product liability and securities law.

Securities Litigation: Williams & Connolly has vast experience in high-stakes securities litigation defending public companies, audit firms, financial institutions, senior executives, officers and directors, lawyers and various other entities and individuals in investigations and trials involving a wide range of securities, banking, financial and accounting fraud matters. These matters have included investigations initiated by the Department of Justice, the Securities and Exchange Commission, the Commodity Futures Trading Commission, the Federal Trade Commission, the Public Company Accounting Oversight Board, state attorneys general and various self-regulatory authorities, among others. Representations have included many SEC enforcement actions (both in federal court and administrative proceedings) and investigations and have covered wide-ranging allegations of securities fraud, stock option backdating, insider trading, other violations of the ’33 and ’34 Acts or the regulations promulgated thereunder and the Foreign Corrupt Practices Act. In recent years, many of these cases have involved the fallout from the 2008 financial crisis.

Legal & Accounting Malpractice: Williams & Connolly devotes a substantial portion of its practice to the defense of major law firms where it has been described by the Washington Post as the “firm that lawyers and law firms turn to when they’re in trouble.” Although W&C does not identify its law firm clients, in 2013 Williams & Connolly was chosen to represent 25 of the Am Law 100 law firms; over the past several years, it has represented nearly half of the Am Law 100. More than 35 partners have handled these cases and they have resulted in favorable decisions in a number of federal courts of appeals, the highest courts of several states, and many intermediate and trial courts. A number of claims have also been settled confidentially before suit when the defendant law firm prefers that course. The selection of Williams & Connolly by the finest firms in America is a recognition of the quality of its work and its reputation for confidentiality. The firm has also defended national accounting firms, including two of the “Big Four,” in dozens of matters involving alleged malpractice, securities fraud, PCAOB and SEC investigations, and personnel matters. Among them are high-profile cases stemming from some of the country’s largest financial frauds with successful outcomes.

Patent Litigation: Williams & Connolly has been practicing complex, high-stakes patent litigation for more than 20 years. Major corporations place their trust in the firm to handle significant intellectual property matters, particularly in patent litigation and related licensing disputes. It has represented both patentees and alleged infringers in cases spanning a wide range of different technologies, from pharmaceuticals to medical devices, from electronics and internet technology to biotechnology, among others. The firm’s patent experience is also brought to bear in other contexts including Hatch-Waxman patent litigation and Inter Partes Review (IPR) proceedings before the patent office. A significant number of the firm’s partners and associates have extensive experience in and devote substantial parts of their practices to, patent litigation. Among these attorneys are nine former Federal Circuit clerks and a number of attorneys who, in addition to their extensive knowledge of patent law, possess technical backgrounds involving a broad range of disciplines.

Product Liability, Torts & Medicine: Williams & Connolly is frequently awarded top ranks in product liability in nationally renowned publications, including recent recognition by a major legal media publication as the Washington, DC Litigation Department of the Year for Mass Torts. These honors flow from years of experience handling personal injury litigation arising from pharmaceutical products, medical devices, consumer products and equipment, as well as from chemical and transportation exposures, accidents and explosions. Williams & Connolly represents pharmaceutical and medical device makers and distributors in all aspects of national and international litigation as: (a) lead trial counsel, (b) national or global coordinating counsel, (c) resolution counsel and (d) appellate counsel. Of late, the firm has represented many pharmaceutical and device companies in federal MDLs, state coordinated proceedings and multi-plaintiff actions. The firm also has a long history of defending doctors and medical institutions in malpractice litigation.
