Drawing on his experience in law, operations, and technology leadership, he advises clients on information governance, data strategy, AI adoption, and technology-driven risk management. He has extensive experience advising life sciences, pharmaceutical, and health care organizations involved in commercial litigation, mergers and acquisitions, antitrust matters, and government investigations.
Prior to rejoining Mintz in 2016, John led the Boston office of one of the nation's leading legal services firms, where he worked with in-house legal departments and law firms to design efficient and cost-effective legal solutions that combined process improvement, technology, flexible staffing, and operational rigor across a broad range of matters, including litigation, compliance, employment, corporate transactions, and contracts management.
During his initial tenure at Mintz, John was a founding member of the firm's Electronic Discovery Practice Group and an active member of the Product Liability and Complex Tort Litigation Practice Group. He maintained a diverse litigation and counseling practice, serving as national trial, strategy, and discovery counsel for pharmaceutical, medical device, and biotechnology companies involved in complex litigation and regulatory matters.
Outside the firm, John frequently lectures, writes, and speaks on artificial intelligence, legal innovation, information governance, data privacy, and legal data intelligence, helping organizations understand how emerging technologies can be responsibly deployed to create meaningful business and legal value.

Three Courts, No Consensus: The Evolving Privilege Landscape for GenAI-Generated Legal Materials
April 29, 2026 | Blog | By John Koss, Emma Follansbee
Three recent federal court decisions have created some uncertainty about whether materials created using generative AI tools are protected by attorney-client privilege or the work product doctrine. In United States v. Heppner, the court held that a party’s use of a consumer AI platform without attorney direction vitiated any privilege protection. However, in Warner v. Gilbarco, Inc. and Morgan v. V2X Inc., courts reached more protective conclusions, holding that AI tools are instruments, not third parties, and that using them does not automatically waive work product protection. These conflicting rulings highlight immediate risks for corporate entities and employees who use AI to research legal issues or prepare litigation-related materials.
