Government Contracts

Arnold & Porter's highly regarded, full-service Government Contracts practice helps clients navigate the unique statutory and regulatory constraints and other challenges confronting firms selling to government customers.

We represent the entire spectrum of domestic and international government contractors, from start-ups to FORTUNE 100 companies, including not-for-profit organizations.

Our clients operate across the vast array of industries supporting the government: aerospace and defense, information technology, professional services, telecommunications, healthcare, pharmaceuticals, insurance, manufacturing, financial services, life sciences, and others.

Strong litigation capabilities. Our respected bid protest practice litigates before all tribunals, and is known for success in many high-profile, high-stakes, and precedent setting cases. We also represent clients disputing substantial claims by and against the government before the Boards of Contract Appeals and US Court of Federal Claims, and prosecute and defend court actions between contractors.

Robust investigation and defense team. Our group includes many former government enforcement lawyers experienced with matters initiated by auditors, inspectors general, the Justice Department, Congress, and whistleblowers, relating to contract performance issues as well as alleged civil and criminal violations of the False Claims Act or other statutes.

Regulatory compliance. Our clients present us with their most complex, arcane and "first impression" issues under the FAR, CAS, and other regulatory regimes. This work includes accounting, cost and pricing requirements, intellectual property/data rights protection, mandatory disclosure, and the wide array of obligations unique to government contractors.

Specialized transactional capabilities. Contractors, investors, and other law firms call on our team to address complications unique to M&A deals and asset purchases/sales involving government contracts. Our work has supported many of the largest transactions in this industry.

Cyber security and privacy. We help clients address not only the increasingly complex cyber issues confronting commercial businesses, but also the additional requirements imposed on government contractors, and the special concerns associated with work for DoD and intelligence agencies.

International procurement. Our clients operate globally and so do we. We assist contractors working with foreign governments in addressing issues arising under US and foreign laws. We also assist foreign contractors in doing business with US agencies.

Unique National Security strength. We advise contractors supporting the defense and intelligence community, and help them address issues arising from overseas operations, specialized technology, foreign ownership, and classified programs.
