In sum, we understand the unique business and legal challenges faced by clients in the A&D industry and that is why clients turn to us when a thorough appreciation of the industry is required to come to grips with issues quickly and efficiently and deliver valuable advice and solutions in real time.

Government Contracts

We have decades of experience representing major aerospace and defense companies that do business with the federal government, including DOD and all civilian agencies. Our attorneys are experienced in a wide variety of government contract issues and disputes. We have successfully advocated our client's position on a variety of challenges, including cost and cost accounting challenges and audits; claims development and litigation before boards of contract appeals, the Court of Federal Claims, and the Court of Appeals for the Federal Circuit; rights in technical data and computer software; “buy national” restrictions; cyber security; terminations; bid protests; teaming agreements; subcontract disputes, litigation, and arbitration; civil and criminal False Claims Act investigations and litigation; and antitrust and intellectual property claims as applied to defense, electronics, aerospace, transportation and other industry enterprises.

Our team has deep and broad capability conducting assessments of corporate compliance programs intended to satisfy required statutory and regulatory mandates. We have a sizeable background in performing internal investigations related to possible violations of the maze federal statutes and regulations that permeate the A&D space.

Our lawyers have published a six part series on Government-wide and DOD-peculiar cyber security compliance, the definitive book on GSA’s Multiple Award Schedule Program, and a Cloud Computing guidebook.

We also have extensive experience representing entities in the transportation sector and other industries in administrative and judicial challenges to federal and state agency decisions, rulemakings and investigations. And we have, on multiple occasions, successfully challenged user fees that have been unlawfully imposed by the federal government.


Our corporate attorneys are deeply experienced in M&A and private equity transactions, early and later stage venture financings, SEC compliance, public offerings, and corporate joint venture and other strategic alliance arrangements. Because of our diverse client base, our experience ranges from structuring and executing complicated domestic and multinational transactions, preparing commercial agreements to address unique business arrangements, and advising smaller and emerging clients on the full spectrum of business matters.

Our M&A and private equity practices are among the most active transactional practices in the A&D industry throughout the United States and overseas and includes a savvy and talented group of attorneys with deep sector experience and relationships. We have advised our clients on all forms of M&A transactions, leveraged buyouts, management buyouts, recapitalizations and other corporate restructurings. Our attorneys have been involved in transactions which have been both friendly and hostile, have advised both foreign and domestic participants on cross-border transactions and have utilized a myriad of acquisition structures and forms of consideration to help accomplish our clients' goals. We have also been engaged on numerous occasions to serve as special counsel to boards of directors and to independent director committees.

Our combination of skills in the transactional world allows us to provide broad, in-depth, economical support to assist our clients in achieving their objectives.

Trade Control Compliance

Firms in the aerospace and defense industries are typically subject to a range of export control laws that materially affect their business operations and international sales. The movement of goods and information across borders – whether as finished products, parts and components, demonstration models, or selling aids is subject to an intricate web of regulations promulgated by United States agencies. We assist our clients to understand and address their most vexing trade controls issues. We advise clients on complying with U.S. export controls under the ITAR and the EAR, especially complicated issues involving technology transfers. We counsel clients on complying with U.S. sanctions regulations, which evolve frequently in connection with U.S. foreign policy directives. We work with clients to understand their obligations under the byzantine anti-boycott rules, and under the many facets of U.S. import law. And we assist clients with their toughest issues under the FCPA, the U.S. anti-corruption law that is being enforced more aggressively now than ever before.


Our attorneys handle a range of complex litigation and arbitration matters for aerospace and defense firms in both state and federal court. In this connection, we have represented clients in matters involving both state and federal agencies. We have also represented clients with respect to complex government and commercial contract disputes, including bid disputes, contingent payment claims, liquidated damages claims, back charge and change order claims, construction defect claims, bond claims, and insurance coverage disputes. Our experience in such matters can often help bring about early and successful settlement of disputes. But if litigation is necessary, you can count on our experienced trial attorneys to vigorously represent your interests.

Antitrust & Competition

The team is ranked highly by Chambers and Legal 500 and includes former enforcement officials and trial lawyers from the U.S. Department of Justice, U.S. Federal Trade Commission, and the European Commission’s Directorate General for Competition. From investigations to litigation to merger control, our team can assist aerospace and defense companies succeed.

Because the infusion of capital is one of the pillars of success for many businesses, all industries are dependent upon the lender/borrower relationship. However, not all industries are the same, and many require very specific knowledge of specialized laws, deal structures and the like.

Our understanding of very specific and specialized needs of the aerospace and defense industry allows us to provide clients with a resourceful and economical approach to avoiding pitfalls, resolving challenges, capitalizing on opportunities and thus, successfully closing the transaction at hand. We zealously represent our borrower/issuer clients while preserving a solid and productive relationship with the lenders and underwriters on the other side of the transactions.

Intellectual Property

Our work in the aerospace and defense industries includes drafting and prosecuting comprehensive patent applications, evaluating and rendering opinions about existing and prospective patent portfolios, and defending and enforcing patents in court. In the age of employee raiding and sophisticated industrial espionage, we also work with clients to safeguard proprietary information and protect trade secrets. We also defend clients against overzealous claims alleging such violations. Our attorneys have obtained restraining orders and injunctions protecting our clients' rights and have successfully defended similar actions brought by our clients' adversaries. We also secure and enforce new product names, and negotiate contracts, licenses, export agreements, and technology transfer agreements. We understand the government’s hunger for its contractors’ intellectual property and we know how to maximize protection of that IP from government overreach and misappropriation and infringement by others.

Labor and Employment

Our team has expertise in all matters affecting the workplace, including wage and hour, class and collective actions, discrimination, harassment, retaliation, employment agreements, executive compensation, layoffs, and ERISA. Additionally, our immigration and international labor practices provide global organizations with support within the US and abroad. With our knowledge and commitment to service, our clients view us as an extension of their in-house legal departments.

Employee Benefits and Executive Compensation

Our team works with both public and privately held companies who are faced with creating compensation programs for employees and executives in order to attract and retain crucial talent. Many employers have learned that to effectively grow their companies, they must find ways to compensate employees that contribute to the overall success of the company. We draft stock option and compensation plans, assist employers in establishing procedures for administering stock compensation plans and advise employers regarding stock compensation plan compliance. We also assist employers in developing tailored bonus and commission plans that are based on rewards for contribution and increased revenue of an organization. We advise on all aspects of qualified and nonqualified retirement plan and employee benefits matters including defined contribution and benefit plans, profit sharing and 401(k) plans, supplemental executive retirement plans ("SERPs"), and employee Stock Ownership Plans ("ESOPs"). We understand how these benefits are treated by the government, from a cost accounting perspective, under government contracts and we actively work with our clients in contesting audit results that seek to disallow such costs.

Real Estate

Our team has extensive experience in the representation of clients in real property leasing, and purchase and sale transactions. We negotiate and document real property acquisitions and dispositions, and regularly assist our clients in conducting the "due diligence" investigations required for purchase and sale transactions. This work includes investigations regarding the environmental and physical condition of real property and improvements, lease review, comprehensive review of all related title, land use, zoning issues and contractual obligations.

We also represent both landlords and tenants in commercial leasing transactions. We negotiate and prepare special purpose high rise ground leases for urban high rise buildings, corporate headquarters, campuses and free standing retail facilities. We also negotiate leases with the United States General Services Administration, as well as with many state and local government agencies.

We counsel clients in connection with site assessments prior to purchasing, selling, leasing or lending secured by real property. We also negotiate and document remediation activities, both with private parties and with governmental authorities. We represent clients in connection with CERCLA enforcement actions, clean-up and abatement orders, underground storage tank regulation, removal and remediation of hazardous substances, hazardous waste storage and transportation, the permitting of facilities which handle or store hazardous waste and private contamination litigation. We have also represented clients in proceedings before the Air Quality Management District Boards and have counseled clients with respect to asbestos removal procedures and asbestos related injury and abatement cases.


We assist clients in structuring transactions and planning business affairs in order to reduce income, sales, transfer, property and other taxes. Our goal is to help our clients achieve their business objectives with practical and effective tax reduction planning. We have also handle tax related matters in state and federal courts and before the United States Tax Court.
