Recent developments in U.S. merger regulations highlight the importance of compliance with the Hart-Scott-Rodino (HSR) Act. A Department of Justice (DOJ) complaint emphasizes the need for careful preparation of interim operating covenants to avoid violations. Additionally, new HSR premerger notification requirements have taken effect, further complicating the merger landscape. Legal experts are advising businesses on how to navigate these changes, including the impact of new government cost-reduction initiatives at the U.S. Patent and Trademark Office (USPTO). Firms are encouraged to prepare adequately for the new merger review process to ensure compliance with the latest regulations.
