What you’ve built, we can defend. What you envision, we can help construct.

Business Law. The firm serves as a trusted adviser and lead dealmaker on behalf of an impressive roster of corporate clients. Our attorneys are recognized as among North America’s most practical and creative corporate practitioners. Rarely is the path from point A to point B a straight line, so our role is to find alternatives, devise workable strategies, and keep projects moving forward to completion. Cozen O’Connor’s business attorneys help clients achieve their goals with respect to mergers and acquisitions, venture capital, intellectual property, real estate, utility & energy, environment, securities, tax, transportation & trade, employee benefits and executive compensation, bankruptcy, public and project finance, insurance corporate and regulatory, privacy and data security, and health care and life sciences.

Litigation. Cozen O’Connor’s historical roots are in litigation, and we are widely known as one of the top trial firms in North America. Our long track record of aggressive and innovative advocacy gives us an edge both in court and in negotiations. We have experience resolving many types of disputes, including in the areas of complex commercial litigation, class actions, intellectual property, labor & employment, securities, antitrust, product liability, aviation, construction, environment, insurance claims & litigation, and criminal defense and government investigations.

Government Relations. Cozen O’Connor’s strength in government relations comes from our deep legal and political experience combined with business strategy to deliver results for our clients. Our State AG practice group was one of the first firms to establish a team dedicated to representing clients in AG investigations and litigation, and counseling clients on state AG matters. Our attorneys work at the cutting edge of issues, including antitrust, cybersecurity, data privacy, consumer protection, the environment, and labor laws. Complementing our legal practices, our bipartisan government relations firm, Cozen O’Connor Public Strategies, is based in Washington, D.C., with offices throughout the United States. The group serves clients on the federal, state, and local levels and before both the executive and legislative branches of government. Public Strategies professionals have held high-level political positions in Republican and Democratic administrations; worked for members of Congress and congressional and state committees; and run federal, state, and local political campaigns. The team helps ensure that clients are seen and heard by key decision-makers and provides critical crisis management and public relations counsel.
