Arnold & Porter

Recognized as a premier choice for some of the world’s biggest companies, Arnold & Porter's antitrust group remains active on complex, business-critical merger mandates for industry titans such as Pfizer, BP, and Boston Scientific Corporation. The team is regularly called upon to handle DOJ and FTC clearance proceedings, investigations, and litigation, as well as securing approvals for mergers across multiple jurisdictions. The Washington DC-based team is jointly led by Debbie Feinstein and Jonathan Gleklen. Feinstein, previously serving as the Director of the FTC Bureau of Competition, is distinguished for her specialized expertise in merger and acquisition reviews, civil investigations, and litigation. Meanwhile, Gleklen brings substantial experience in high technology network industries, encompassing government merger review, investigations into alleged anticompetitive conduct, civil litigation, and counseling. Michael Bernstein is another key port of call for leading public and private companies involved in high-profile mergers, investigations, and litigation, currently lending his expertise to BP’s significant acquisitions and divestments. Matthew Tabas has handled complex antitrust issues for major clients such as Intel, Pfizer and Fitbit. The team has been strengthened by the arrival of David Emanuelson who was the former Associate General Counsel for Intel.
