Overview
Strategic defense of privacy and technology litigations and regulatory investigations

The collection, use, and disclosure of personal data, along with the deployment of evolving technologies, create significant legal and reputational risks for companies across every sector. These risks can stem from the collection of sensitive data, the implementation of new technologies, a data security incident, or other different data use cases.

McDermott’s Privacy, Data & Technology Litigation Practice Group is a top-ranked team, consistently recognized for successfully handling complex, high-stakes disputes. Clients rely on our sophisticated legal judgment, credibility with courts and adversaries, and disciplined approach to managing risk.

Our team represents clients in litigation, regulatory investigations, and enforcement actions involving privacy, cybersecurity, data governance, and emerging technologies. The team regularly defends organizations in class actions, arbitrations (individual and mass), multidistrict litigation, and government investigations brought by the Federal Trade Commission (FTC), US Department of Health and Human Services Office for Civil Rights, Federal Communications Commission, state attorneys general, and other federal and state regulators.

Results
  • Represented a major accounting firm in high-stakes litigation against one of its clients following a data security incident that the client blamed on the accounting firm. We leveraged our deep knowledge of security incidents to successfully obtain a resolution for the accounting firm at a fraction of the initial demand.
  • Represented a large digital advertiser in the health marketplace in connection with a Civil Investigative Demand (CID) from the FTC. Succeeded in obtaining a substantial narrowing of the investigation and resolution without any public enforcement action.
  • Successfully defended nonprofit hospitals before the Massachusetts Supreme Court in parallel putative class action lawsuits over alleged use of advertising and analytics technologies on their websites.
