The Health Care Division investigates the business activities of physicians and other health professionals, pharmaceutical companies, institutional providers, and insurers, and also reviews mergers involving health care products and services. The Division’s early work led to several landmark cases in the Supreme Court and lower federal courts applying antitrust law principals to conduct by physicians, hospitals, and other health care providers. Today, a major focus of the Health Care Division is the FTC’s effort to stop anticompetitive pay-for-delay agreements among pharmaceutical companies that unlawfully insulate branded drugs from competition from lower-cost generic drugs. The Division also provides guidance on health care competition to policy makers, federal and foreign agencies, industry, and the public; much of this guidance is available on the Health Care webpages.

ACP I has long been responsible for the Bureau’s enforcement efforts against anticompetitive conduct in industries other than health care, pharmaceuticals and digital technology. ACP’s work involves not only stopping illegal conduct but also shaping the law. ACP’s ongoing work includes issues of intellectual property rights, attempts by professional and regulatory boards to limit competition, and immunities from and exceptions to the antitrust laws. In the area of industry standard-setting, ACP has become well-known for a series of cases involving anticompetitive conduct by members of standard-setting organizations.

ACP II, the Bureau’s newest Division, has been formed to enhance the Bureau’s capacity to investigate and challenge anticompetitive business practices in a broad array of industries. The Division’s work will seek to stop illegal conduct and also shape the law, with a particular emphasis on investigating and litigating charges of unilateral and coordinated anticompetitive conduct and unfair methods of competition. We are excited to grow the Bureau, expand our non-merger work, and develop ACP II’s portfolio of enforcement matters.
