Facing litigation in the United States is unlike facing litigation anywhere else in the world. Regardless of the parties, regardless of the issues, and regardless of the amount at stake, litigating in the U.S. is a complex proposition, and there are many important and strategic decisions that need to be made.

Our firm represents foreign companies and their executives in business litigation with U.S. companies and the U.S. government. This includes litigation involving civil and commercial disputes as well as enforcement matters involving the U.S. Department of Justice (DOJ) and other federal agencies. With a practice that is nationwide in scope and with local counsel in most major jurisdictions across the country, we are able to efficiently and effectively represent foreign entities and foreign nationals in U.S. litigation regardless of where their needs arise.

A U.S. Based Litigation Law Firm with Strong Capabilities for Representing International Clients

There are several aspects of our practice that make Oberheiden P.C. stand out from other law firms. First and foremost is our nationwide network of civil litigation attorneys and litigation consultants. Our firm’s unique structure allows us to provide defense representation for federal litigation throughout the United States without the overhead of a large law firm with hundreds of junior associates and paralegal staff members. All of our International litigation lawyers have senior-level experience, and many previously served as attorneys for the U.S. government at the DOJ and other agencies.

Our consultants help us stand out as well. In addition to our attorneys, we also have non-lawyer experts who are available to consult on our clients’ litigation matters on an as-needed basis. Our consultants come from diverse professional backgrounds, having served in the Federal Bureau of Investigation (FBI), the Internal Revenue Service (IRS), and numerous other federal agencies. We also have investigators available to collect evidence in the United States on behalf of our foreign clients.

We have deep experience in transnational matters. This includes experience gained investigating and prosecuting foreign entities and foreign nationals as U.S. government attorneys and agents, as well as experience defending companies and individuals in U.S. litigation. From import-export issues to disputes involving cross-border contracts, we are able to adeptly represent international clients in all types of U.S. litigation, and we have an extensive success record to prove it.

Our senior attorneys and consultants speak languages including:

  • Arabic

Civil and Commercial Litigation Involving U.S. Companies

We represent foreign companies and their executives in civil and commercial litigation involving U.S. companies. If your company (or you personally) have been sued and a U.S. company is seeking to obtain jurisdiction and venue in the United States, we can defend against the litigation on both procedural and substantive grounds. If a U.S. federal district court is not the proper forum, we can seek to have the lawsuit dismissed in its entirety without needing to address the merits of the plaintiff’s claim. If jurisdiction and venue are proper, then we can defend you and your company in the litigation on substantive grounds—and we will do so by all means available.

Our civil and commercial litigation practice encompasses all types of disputes between U.S. and foreign parties. We represent transnational businesses and their executives in matters including, but not limited to:

Contract Litigation

Our commercial litigation law firm handles U.S. litigation involving all types of business and commercial contract disputes. From supply agreements to the contracts underlying cross-border corporate acquisitions, if you need defense counsel for a contract dispute in the United States, our attorneys have the experience you need.

Intellectual Property Litigation

We represent foreign parties in U.S. litigation involving infringement allegations and other intellectual property-related matters. We defend foreign companies and foreign nationals against claims involving patents, trademarks, trade secrets, copyrights, and other intangible assets registered in the U.S. and abroad.

Trade and Counterfeiting Litigation

A significant portion of cross-border litigation between U.S. and foreign companies involves disputes related to trade—and specifically related to counterfeiting. We defend foreign clients in all U.S. jurisdictions in matters involving domestic and international trade.

Investment and Securities Litigation

We represent foreign companies and their executives in U.S. litigation involving business investments and their federal securities law implications. This area of the law is extraordinarily nuanced and complexed, and presenting a sound defense requires a thorough understanding of the statutory provisions and court decisions that apply.

Antitrust Litigation

Litigation between U.S. and foreign entities often involves issues in the area of federal antitrust law. We represent foreign companies and their executives in litigation involving alleged violations of the Sherman Act, the Clayton Act, the Federal Trade Commission Act, and all other pertinent laws and regulations.

Judgment Enforcement Litigation

If a U.S. company has obtained a judgment against your company and your company has assets in on U.S. soil, our firm can defend against efforts to enforce the judgment in the United States. We have significant experience handling enforcement and collection matters on behalf of our clients, including matters involving the U.S. Office of Foreign Asset Control (OFAC).

International Arbitration in the U.S.

International arbitration is an effective tool for resolving many types of disputes between U.S. and foreign entities. If your company is subject to a contractual obligation to arbitrate in the United States, or if pursuing non-contractual international arbitration is in your company’s best interests, our transnational litigation lawyers and consultants can help you pursue an efficient and favorable result without going to court.

U.S. Government Litigation and Enforcement Matters

If you are facing litigation involving the U.S. government, you need a law firm with attorneys who have extensive experience in high-stakes federal matters. With our attorneys’ experience on both sides of U.S. federal law enforcement litigation, we are well-positioned to defend international clients regardless of the reason for the U.S. government’s scrutiny. Our international litigation attorneys represent foreign companies and individuals in U.S. government matters involving:

Anti-Bribery and Corruption Litigation

The Foreign Corrupt Practices Act (FCPA) prohibits foreign companies and foreign nationals from attempting to improperly influence the acts of U.S. government employees and officials. Several of our commercial litigation lawyers have extensive experience in matters involving the FCPA, and we are able to represent foreign clients in FCPA investigations and prosecutions throughout the United States.

Antitrust Litigation

In addition to representing international clients in private litigation under federal antitrust laws, we represent foreign businesses and foreign individuals in antitrust enforcement matters involving the DOJ’s Antitrust Division and the U.S. Federal Trade Commission (FTC) as well. If the Antitrust Division or the FTC is looking into your company’s business practices in the United States, our defense lawyers can intervene and work to prevent charges from being filed.

Controlled Substances Litigation

We have extensive experience in federal enforcement matters under the Controlled Substances Act. If the DOJ, the FBI, or the U.S. Drug Enforcement Administration (DEA) is investigating your company for alleged violations involving prescription medications, over-the-counter medications, or illicit drugs, our lawyers can use their experience to help you seek to avoid the severe consequences of a federal criminal conviction.

Import-Export Litigation

In addition to matters involving controlled substances, we represent international clients in U.S. enforcement matters involving all other types of products as well. Our international litigation law firm has extensive experience in the area of U.S. import-export law, and we can fight to ensure that you are your company are not unduly prosecuted or penalized for alleged violations.

Immigration Litigation

Immigration compliance is a top law enforcement priority for the U.S. government. In particular, foreign companies seeking to do business in the United States are facing intense scrutiny in all aspects of their operations. If you or your company is under investigation or facing prosecution in the United States for alleged immigration violations, our defense attorneys can get to work on your case immediately.

Securities Litigation

The U.S. Securities and Exchange Commission (SEC) is extremely active in its enforcement efforts, including its efforts to target foreign entities suspected of attempting to defraud U.S. investors. From unregistered initial public offerings (IPOs) and initial coin offerings (ICOs) to material misrepresentations and omissions in registered companies’ public disclosures, there are numerous different types of issues that can lead to trouble with the SEC for foreign companies.

Tax Litigation

The Internal Revenue Service (IRS) is extremely active in enforcing foreign entities’ and individuals’ obligations under U.S. law as well. We represent international clients in civil and criminal tax litigation in the United States, including (but not limited to) matters involving IRS Criminal Investigations (IRS CI), the Financial Crimes Enforcement Network (FinCEN), and the Joint Chiefs of Global Tax Enforcement (J5).
