Roy P. Lessy, Jr., a senior partner in the firm’s Antitrust and Energy practices, represents clients on a wide array of matters.  In the Antitrust Practice, Mr. Lessy regularly provides legal counsel and litigates on behalf of regulated and non-regulated industries including companies in the energy, technology, transportation, healthcare, and industrial sectors in a wide range of antitrust matters. In the Energy Practice, he assists electric utilities, industrial companies, high-technology firms, and large engineering firms that provide services and products to the nuclear and electric utility industries.

In the Antitrust area, Mr. Lessy has been involved as counsel for numerous successful mergers and acquisitions, and in numerous successful Hart-Scott-Rodino filings associated with mergers and acquisitions. In addition, he has successfully represented clients at the trial and appellate levels involving:

Sections 1 and 2 of the Sherman Act;
The Clayton Act;
The Federal Trade Commission Act; and
The Robinson-Patman Act.

Mr. Lessy has successfully represented major companies and executives in investigations conducted by the Antitrust Division of the Department of Justice (DOJ), including the National Criminal Enforcement Section of the Antitrust Division, as well as investigations conducted by the Federal Trade Commission (FTC).

In the area of antitrust litigation, Mr. Lessy has been counsel or co-counsel in a number of high-profile antitrust cases, including some of the first cases including the development and application of U.S. v. Otter Tail Power Co., price-fixing cases, and cases involving the extra-territorial effect of the U.S. antitrust laws.

In the Energy area, Mr. Lessy’s knowledge and experience in the energy industry enable him to advise domestic and international clients on myriad issues, including nuclear energy, electric utilities, antitrust matters, environmental and land use issues, project and infrastructure development, and global security matters. He regularly counsels and litigates on behalf of nuclear licensees and electric utilities, and represents clients before federal entities, including the Nuclear Regulatory Commission (NRC), DOJ, and the FTC, and in federal and state courts. He helps clients navigate complex regulatory issues involving nuclear waste and nuclear contamination, and has represented a number of companies before the Department of Energy.

Mr. Lessy’s tenure as Deputy Chief Hearing Counsel and Senior Antitrust Counsel of the NRC, coupled with his experience in private practice, has placed him at the forefront of matters involving nearly half of all licensed nuclear reactors in the United States. He has been involved in the purchase and/or sale of a number of nuclear plants, including due diligence reviews, license transfers, and corporate restructuring. He has also served as chief counsel and director of a special interagency task force, which involved four federal government agencies, assembled to examine radioactive waste litigation.

Additionally, Mr. Lessy appears before industry groups and electric utilities on management prudence issues and nuclear regulatory issues. Public policy decision-makers in the executive and legislative branches regularly call on him regarding proposed statutory developments. He has appeared before more than a dozen state public utility commissions (on behalf of electric and nuclear utilities) regarding the recovery of investment in large-scale generating units and outages at nuclear and fossil-fuel generating plants.

Mr. Lessy has substantial experience in the oil and gas industry, including the representation of oil and gas exploration companies, both domestically and abroad, and the representation of U.S. based and non-U.S. based oil and gas companies.

Mr. Lessy has been actively involved in industry committees of the Antitrust Section of the American Bar Association and has provided comments to the author of a leading antitrust casebook used in many law schools.

Before joining Patton Boggs, Mr. Lessy was a partner at a prominent Washington DC-based firm.
