Health Care Litigation

Sign Up for Publications

Quinn Emanuel has one of the leading healthcare litigation practices in the United States. The firm has deep substantive healthcare law expertise, unparalleled investigative experience, and a willingness and ability to try these cases to a jury if necessary. These skills have been brought to bear to achieve an extraordinary record of successful outcomes for our health care clients.

Our representations in healthcare litigation matters have included consumer class actions, regulatory actions against a variety of state and federal agencies, False Claims Act/qui tam actions, ERISA claims, employment cases, personal injury and mass torts claims, criminal/white collar actions, and intellectual property suits (including Hatch-Waxman litigation, traditional patent infringement litigation, and copyright and trademark litigation). These cases have arisen in virtually every context of healthcare, such as individual physicians and hospitals involved in direct provision of services to patients, drug manufacturers marketing products to doctors and wholesalers, and diagnostic testing companies that provide services to various end-users. We have substantial expertise in the federal anti-kickback statute, Stark Law governing self-referrals, and the legal and regulatory environment governing the off-label marketing of drugs and devices. Our firm is also at the cutting edge in using claims and billing data to support our clients’ defenses and undermine the opposing parties’ theories of liability. We represent industry leaders and individuals as well as small and emerging companies and organizations.

Many of our matters involve a significant overlap of criminal and civil enforcement efforts, and require strategic planning to navigate those issues effectively. More than 20 of our litigators are former federal prosecutors, many of whom prosecuted criminal healthcare fraud cases and coordinated with civil healthcare enforcement authorities while with the government. Many of our attorneys are scientists or engineers with degrees in relevant fields; more than 140 of our litigators hold degrees in physics, chemistry, pharmacology, molecular biology, biochemistry, and chemical engineering. One of our partners is also the former general counsel of a major pharmaceutical company. On the appellate level, our attorneys have argued—and won—some of the biggest health care cases in the United States. Our litigators are not only scientists, but also veteran trial attorneys. Our success in the courtroom in healthcare matters speaks for itself.

Based on a California statute, known as the Confidentiality of Medical Information Act, which appears to allow certain damages without proof of injury, plaintiffs were seeking approximately $2 Billion. After the cases were consolidated in the Eastern District of California, we filed a motion to dismiss the consolidated cases on standing grounds. During the months that the motion was pending, we also managed to stave off discovery by demonstrating to the Judge that they had a robust motion to dismiss and that causing IBM to engage in discovery before the motion was decided would be a miscarriage of justice.


  • We represented Pfizer in a unanimous victory in the U.S. Court of Appeals for the Second Circuit, which affirmed dismissal of off label marketing claims brought against Pfizer under the qui tam provision of the False Claims Act.
  • We obtained a 7-2 victory in the U.S. Supreme Court for Roche against Stanford University in a suit involving patents related to HIV treatment that had been developed in a collaboration between Stanford and Roche’s predecessor, Cetus Corporation. The Court held that Roche was a co-owner of the patents in suit and rejected Stanford’s effort to void its prior contracts based on its receipt of federal funding, reasoning that the Bayh Dole Act—the statute governing federal research funding—does not give automatic ownership of patents to universities.
  • We secured a 6-2 victory for Wyeth LLC (part of Pfizer Inc.) in the U.S. Supreme Court in Bruesewitz v. Wyeth, which held that the National Childhood Vaccine Injury Act preempts state-law causes of action based on theories of defective design in governmentally-approved child vaccines. The decision has significant implications for public health and the vaccine supply, as it removes design-defect claims that if permitted would have increased manufacturers’ costs and depressed vaccine supply and development.
  • We represented Ortho-McNeil, a Johnson & Johnson subsidiary, in a unanimous Seventh Circuit victory that made new law narrowing “manifest disregard of the law” as a ground for district court vacatur of arbitral awards and reversed a partial vacatur of an award that had favored Ortho in a dispute over ownership of two patent families relating to new biological drugs for the production of red blood cells.
  • We obtained a victory in the Ninth Circuit for Sequus Pharmaceuticals, Inc. (a subsidiary of Johnson & Johnson) that strengthened protection of foreign arbitral awards by holding that the removal provision of the Convention on the Recognition and Enforcement of Foreign Arbitral Awards (the “New York Convention”) should be construed broadly to prevent state-court end runs around foreign arbitration.


  • The firm represented Express Scripts in a breach of contract and antitrust action in the Eastern District of Missouri in connection with Express Scripts’ termination of compounding pharmacies from its network.  Plaintiffs sought over $120M in damages. This was only the second case that Express Scripts took to trial in the history of the company—in the first case, Quinn Emanuel obtained a jury verdict in Express Scripts’ favor.  In the lead-up to trial, Quinn Emanuel moved for and obtained what were effectively case-terminating sanctions for Plaintiffs’ discovery violations; the Court awarded Express Scripts $360,000 in monetary sanctions, struck Plaintiffs’ damages expert, and invited supplemental summary judgment briefing.  Four days before the start of trial, the Court granted summary judgment in Express Scripts’ favor on all of Plaintiffs’ claims to be tried and held that Plaintiffs were liable on Express Scripts’ counterclaims, leaving only the amount of Express Scripts’ damages for the jury to decide.  Following the Court’s decision and during jury selection, Plaintiffs agreed to a $20M consent judgment, the full amount of damages sought by Express Scripts.  This completed a string of victories that QE obtained for Express Scripts in five antitrust cases after taking over their defense from prior counsel.

  • We secured a 9-figure settlement for a pharmaceutical company in several contract disputes arising out of drug and device development collaboration and licensing agreements, without having to file suit or request arbitration. This was a prime example of the “Quinn Emanuel Effect,” where our appearance, reputation, and initial strategic initiatives resulted in an early and highly favorable outcome.
