Benjamin R. Dryden



Benjamin Dryden is an antitrust lawyer and serves as the vice chair of the Firm’s Antitrust Practice Group. His practice focuses on the antitrust issues that arise in mergers and acquisitions. His experience includes advising clients on the antitrust risk profiles of potential transactions, counseling clients through the due diligence and integration planning processes, negotiating antitrust risk provisions in purchase agreements, and representing clients in investigations before the Department of Justice, Federal Trade Commission, and state attorneys general. He has particular experience with transactions in the hospital, health insurance, and manufacturing sectors. Benjamin also provides a broad range of antitrust counseling and compliance services, with particular focuses on healthcare and antitrust issues relating to labor and employment.

In his M&A practice, Benjamin regularly represents clients in merger investigations before federal and state antitrust enforcers, including “Second Request” merger investigations. Because Second Requests can require sorting through massive volumes of documents in a short amount of time, Benjamin is an expert at leveraging artificial intelligence to achieve the best results in the quickest, most cost-effective way. In 2023, the legal technology company Relativity named Benjamin an “AI Visionary” for his innovative work deploying artificial intelligence in Second Requests.

In addition, Benjamin helps clients navigate the complex requirements of the Hart-Scott-Rodino (HSR) Act. He has prepared well over 100 HSR filings and routinely advises clients on the intricate HSR reportability rules. He also negotiates and oversees “clean team” agreements to ensure compliant information sharing throughout the due diligence and integration planning processes.

Benjamin provides a broad range of antitrust counseling services, ranging from one-off counseling questions to employee compliance trainings and full-scale antitrust audits. Benjamin complements his legal and industry knowledge with a down-to-earth, plain-spoken style, allowing him to effectively communicate complex concepts with a broad range of audiences. Benjamin is a sought-after speaker on antitrust topics, with quotes in publications such as the Wall Street Journal,, Reuters, and Bloomberg Law, as well as dozens of articles to his name.

Finally, Benjamin maintains a broad practice representing businesses in complex civil litigation. He has litigated antitrust, constitutional law, breach-of-contract, and regulatory disputes in federal and state courts across the country. Representative litigation matters include:

  • Association of Equipment Manufacturers v. Burgum, 932 F.3d 727 (8th Cir. 2019), 2017 WL 8791104 (D.N.D. 2017) — Successful challenge to the North Dakota Farm Equipment Dealership Statute under the Contracts Clause of the United States Constitution.
  • Lloyd’s Material Supply Co. v. Regal Beloit Corp., 2017 WL 5172206 (C.D. Cal. 2017) — Achieved full dismissal of antitrust claims on grounds including lack of actionable conduct and lack of plausible antitrust injury.
  • Central Telephone Co. of Virginia, Inc. v. Sprint Communications Co. of Virginia, Inc., 715 F.3d 501 (4th Cir. 2013), 759 F. Supp. 2d 789 (E.D. Va. 2011) — Successfully recovered more than US$25m for the plaintiff, for breach of telecommunications interconnection agreements; the trial court described the defense as “founded on post hoc rationalizations … as part of [the defendant’s] cost-cutting efforts, and the witnesses who testified in support the defense were not at all credible.”
