Welcome to the April 2025 edition of the Jenner & Block Japan Newsletter, a publication containing updates about legal developments in the United States that may be noteworthy to our clients and other leaders in the Japanese legal and business communities.
Returning to the substance of our Newsletter, this edition spans a wide array of legal topics, including a review of a recent lawsuit highlighting the importance of Hart-Scott-Rodino Act compliance for companies pursuing a merger or acquisition. We also provide an overview of the landscape for financial technology companies in the United States, which has seen significant shifts in 2025.
This edition of the Newsletter also covers the recent pause of Foreign Corrupt Practices Act (FCPA) enforcement and the importance of maintaining FCPA compliance regardless of the current enforcement climate. We then review recent decisions by the Delaware Supreme Court and Delaware Court of Chancery that touch on the importance of drafting narrowly tailored restrictive covenants and precisely drafted earnout provisions. That article is followed by an examination of a trade secret ruling that resulted in a $17 million attorney fee award. Furthermore, we provide an overview of the recently enacted California AI Transparency Act. The new statute sets disclosure requirements for generative AI companies. Also covered is a class action suit regarding the claimed existence of microplastics in consumer products and a patent decision that may raise costs for companies facing infringement allegations. Finally, the Newsletter discusses a decision by the US Supreme Court clarifying the circumstances under which victims of a foreign state’s expropriation of property can seek redress in US courts.
We hope that you find the information in the Jenner & Block Japan Newsletter of interest and helpful to your law practice or business operations. We thank you for taking the time to review our publication.
