摘要:The May 2016 enactment of the Defend Trade Secrets Act of 2016 (DTSA), which created a new federal civil cause of action for trade secret misappropriation, raises a host of issues that federal courts will have to consider under their original subject matter jurisdiction, rather than applying state law through the courts’ diversity jurisdiction. This means that for the first time, an extensive body of federal jurisprudence will be developed to govern the civil protection and enforcement of trade secrets in the United States. In addition, due to the DTSA’s changes to the existing federal criminal law governing trade secrets, the Economic Espionage Act of 1996 (EEA), federal courts will be required to further develop their EEA jurisprudence. Because the DTSA is modeled after and includes many provisions taken directly from the Uniform Trade Secrets Act (UTSA), it is widely anticipated that federal courts will consult and rely upon existing case law regarding the UTSA to decide how to apply the DTSA. However, nothing in the DTSA’s language mandates such an approach, and federal courts may elect to depart from state law precedent in some situations. Moreover, there are unique aspects of the DTSA, such as the ex parte seizure provision and protection for whistleblowers, which will raise questions of first impression for the federal courts. Additionally, because preexisting provisions of the EEA will be subject to greater scrutiny due to the number of civil cases that are likely to be filed under the DTSA, unresolved issues under the EEA are also likely to be extensively litigated. While it is premature to catalogue all the issues that litigants may raise in trade secret cases brought under the DTSA, this Article seeks to identify and analyze several major areas of anticipated dispute and to provide a framework for resolving them. Part I begins with a brief introduction to U.S. trade secret law. Part II details the origins and legislative history of the DTSA. Part III discusses the interpretive rules and methodologies that are likely to govern federal courts’ development of a federal jurisprudence of trade secrecy, including the circumstances under which they might rely upon existing state trade secret case law or instead develop a “federal common law” of trade secrecy. Finally, Part IV examines how key provisions of the DTSA should be interpreted in light of these rules and methodologies, organized into four subcategories: (1) “new” language in the DTSA
