Herbert Allen

The co-chair of Honigman’s Antitrust and Unfair Trade Practices Practice Group, Herb Allen defends M&A transactions before FTC, DOJ, and state antitrust enforcers, and litigates antitrust claims in courts around the country. Herb has fifteen years of experience advising companies in heavily scrutinized industries, including health care, pharmaceuticals, private equity, telecommunications, chemicals, manufacturing, sports, and technology.

As the leader of Honigman’s transactional antitrust practice, Herb guides parties through the full range of antitrust issues that can arise in complex M&A transactions from deal inception to closing. Herb regularly represents companies in response to significant merger investigations brought by state and federal antitrust enforcers and has repeatedly won approval for transactions subject to major “Second Request” merger investigations. Herb has experience defending M&A transactions across virtually all sectors of the economy.

Herb has particularly deep experience in the health care and pharmaceutical sectors. Herb currently serves as the chair of the American Health Law Association’s (AHLA) Antitrust Practice Group and has secured antitrust approval for dozens of M&A transactions involving hospitals, physician groups, surgery centers, and pharmaceutical companies, often in acquisitions by in-market competitors. Herb also regularly represents health care companies in complex antitrust litigation matters and frequently advises health care providers on the formation of provider networks and joint ventures.

In his counseling practice, Herb provides strategic guidance on premerger notification issues, including compliance with the federal Hart-Scott-Rodino Act (HSR Act), as well as the growing number of state premerger notification laws. Herb also frequently advises on intellectual property issues, antitrust concerns related to generic drug approval under the Hatch-Waxman Act, the design and implementation of antitrust compliance programs, employment-related antitrust issues such as non-compete and non-solicitation provisions, pricing issues, platform and distribution arrangements, standard-setting initiatives, and joint ventures.

Herb also serves as the outside antitrust counsel to trade associations, providing advice on antitrust compliance and association governance matters.

Herb’s representative matters have included:

• Responding Major “Second Request” Merger Investigations – Herb has successfully guided companies through major “Second Request” merger investigations brought by FTC and DOJ in a variety of industries.
• State of Washington v. Franciscan Health System – Herb successfully represented a health system facing a state enforcer’s lawsuit seeking to unwind two transactions, defeating the merger challenge on a summary judgment motion. This case marked a rare instance where a government enforcer’s merger challenge under Section 7 of the Clayton Act was defeated on a motion for summary judgment.

• In Mylan Pharmaceuticals Inc. v. Warner Chilcott Public Limited Co. (Doryx), Herb helped a pharmaceutical company defeat a “product hopping” antitrust claim on a motion for summary judgment, a result that was upheld in the Third Circuit.
