Core Capabilities

Mergers & Acquisitions

Our antitrust counseling in the area of business combinations alerts our clients to possible antitrust challenges to proposed transactions and assists them in structuring transactions so as to minimize antitrust and competition law risk. We also assist our clients with all facets of the Hart-Scott-Rodino premerger review process, from the requisite filings to persuading the agencies to litigate any challenges, if necessary.

General Counseling

Our broad knowledge and experience with the entire range of antitrust and competition law issues allow us to counsel our clients on a wide variety of business matters with efficiency and sophistication. Our counseling includes such critical matters as price-fixing and Robinson-Patman/price discrimination issues, market and territorial restrictions, supply and distribution agreements, group purchasing arrangements, trade association activities, dealer and franchise arrangements, and exclusive dealerships.

We also advise on joint marketing, information exchanges among competitors, intellectual property antitrust issues, healthcare antitrust matters and the whole spectrum of business activities that have the potential to raise issues under the Sherman Act, the Clayton Act and other state and federal competition laws.


Our attorneys have extensive experience in both civil antitrust litigation and antitrust criminal defense. This experience extends to enforcement actions and proceedings before the Federal Trade Commission, the Department of Justice and other state and federal administrative agencies.

Our litigation and criminal defense representation captures the entire spectrum of antitrust and competition law claims including those involving price discrimination (and Robinson-Patman Act issues), price-fixing, territorial and market allocation, boycotts and refusals-to-deal, exclusive dealing, tying arrangements, resale price maintenance (and other vertical restraints), attempted and actual monopolization, dealer and franchise terminations, intellectual property antitrust claims, antitrust class actions and unfair competition (including FTC Act claims).

Preventive Law and Audits

We have the necessary experience and expertise to develop and implement preventive law programs to help our clients in minimizing risk and obtaining compliance with antitrust and competition laws while still achieving their goals. Our attorneys can provide training sessions that are adapted to our clients’ particular business needs and the needs of different levels of personnel. We can also perform audits of our clients’ businesses to determine whether their existing practices and arrangements are in compliance with applicable antitrust and competition laws.
