Arnold & Porter attorneys, practicing in more than 25 distinct areas of the law, conduct business on six continents. Our global reach, experience, and deep knowledge allow us to work across geographic, cultural, technological, and ideological borders, serving clients whose business needs require US, EU, or cross-border regulatory, litigation, and transactional services.

We provide the full breadth of legal resources to represent all of our clients' interests. Through interdisciplinary collaboration and specialized experience in our clients' industries, we are able to offer truly innovative and effective solutions that align with both clients’ short- and long-term business objectives.

For those clients who cannot afford legal counsel, we maintain a broad and meaningful pro bono practice. With a lengthy record of excellence, we remain committed to the community at large. In 2009, we were one of the top three pro bono firms named by The American Lawyer, with an average of 150 pro bono hours per lawyer.

We set our standards high, expect the best from our attorneys, and return top-tier work on behalf of our clients. Our tradition of excellence is distinguished, and our attorneys are widely respected in the US and abroad. Our attorneys are leaders in their fields, speak frequently throughout the world on the firm's core practice areas, and are published widely in legal journals, industry and mass media, and "hot topic" books.

Our team is not only comprised of top lawyers from America and Europe's best colleges and law schools, but of doctors, biologists, chemists, public policy professionals, and former high-ranking officials from the US government. In fact, over 80 of our partners have served in positions in the US government, from the Federal Trade Commission to the Department of Justice to the US Congress. Their insider perspectives are integral to understanding the legal and policy frameworks in which complex business and legal issues arise, and how best to structure transactions and overcome litigation and regulatory challenges.
