Dr. David Adler is a dual-qualified attorney with extensive litigation and arbitration experience in the United States and Germany.  David’s practice focuses on both plaintiff and defense-side representations in high-stakes and complex litigation, with a particular focus on antitrust, unfair competition, and IP litigation, including class actions.  David has an active trial practice, and has appeared and argued in a variety of forums, including in federal and appellate courts as well as in arbitrations and mediations.  Prior to joining Quinn Emanuel in New York, David worked at the firm’s Hamburg and Zurich offices where he successfully represented prominent U.S. and international technology companies in connection with the “smartphone wars” and various Swiss banks in connection with investigations conducted by the U.S. Department of Justice and other government agencies.  David was recognized by The Best Lawyers in America: Ones to Watch, Commercial Litigation, Litigation – Antitrust, Intellectual Property, 2024.

Prior to joining the firm, David clerked for the Honorable Dr. Jurgen Danz (Ret.), Chief Judge of the Commercial Division of the District Court in Wuppertal, Germany, and taught at the University of Hamburg. He has published a number of books and articles on international litigation, intellectual property, and trade matters.  His dissertation on 28 U.S.C. § 1782(a) - which discusses the mechanisms that allow foreign litigants to obtain discovery in the United States for use in foreign proceedings - has been acclaimed as “highly impressive,” containing an “immaculate analysis” and being “an enrichment to the library of every law firm and party who has practical contacts with the U.S. discovery system.”
