Noah M. Leibowitz focuses his practice on intellectual property and complex litigation, and particularly on matters involving scientific, technical and medical expertise in the pharmaceutical, biotechnology, healthcare and high-tech sectors. Leveraging his scientific and technical expertise, Mr. Leibowitz has significant experience leading trial teams as first chair counsel in patent jury trials. He has represented innovator pharmaceutical companies in Hatch-Waxman cases, as well as pay-for-delay antitrust litigation, and litigation and arbitration over licensing and drug development deals. In addition, he negotiates complex intellectual property license agreements and provides advice on intellectual property issues in merger and acquisition transactions and securities offerings. Mr. Leibowitz has taken part in over 100 consummated or contemplated transactions and offerings for clients ranging from leading technology companies, to pharmaceutical companies at the forefront of innovation.
In 2024, Mr. Leibowitz was recognized as a patent “IP STAR” by Managing Intellectual Property. He is also routinely recognized by IAM Patent 1000 as a leading patent litigator in New York, where in 2024, he was described as a “litigator with a prowess for the life sciences; his patrons value his commitment to protecting their patents both through litigation and through preventative measures, including assessing potential infringements and risks, nationally and internationally.” In 2023, IAM noted him as being “at his best when operating in the high-technology industry.” In 2022, IAM described Mr. Leibowitz as having "abundant experience leading trial teams in Hatch- Waxman cases," and in 2020, hailed him for “the business sense he brings to litigation, cultivated through extensive involvement in transactional IP practice." He has previously been recognized by Super Lawyers as a leading intellectual property litigation lawyer in New York and has authored numerous articles in legal publications. He co-authored the chapter on "Special Considerations in Hatch- Waxman Litigation" in the second and third editions of Anatomy of a Patent Case, prepared by the Complex Litigation Committee of the American College of Trial Lawyers, as well as the chapter on American law in Intellectual Property in the Life Sciences.
