In helping his clients determine whether and when to get into the market, Andrew’s goal is to prepare a comprehensive pre-litigation strategy that allows for confident, well-informed and well-timed decisions.

Andrew is an associate in Merchant & Gould’s New York office. He focuses his practice on IP counseling matters and Hatch-Waxman litigation. He assists pharmaceutical, biotechnology, and chemical companies with developing and strengthening their IP estates and their litigation strategy, including pre-litigation activities and Paragraph IV Certifications, filings, fact and expert discovery, claim construction advice and briefing, and deposition and motion practice.  Andrew also dedicates significant time to freedom-to-operate, validity and infringement investigations, and post-grant proceedings at the USPTO (including interference and inter partes review), as well as due diligence, licensing, patent procurement and life cycle management advice for a wide range of industries.

Throughout his academic and legal career, Andrew has garnered an extensive technical understanding within multiple disciplines, including organic, medicinal, organometallic and polymer chemistry, which has allowed him to provide a thorough, and often unique, perspective on how to navigate the existing IP landscape. This diverse experience set is invaluable to his legal practice relating to, for example, pharmaceutics and pharmaceutical dosage form design, diversity oriented synthesis and the preparation and screening of large chemical libraries, x-ray crystallography and solid-state drug forms, catalyst design, plastics and adhesives, CNTs and other nanotechnology, semi-conductors, LCD and LED displays, solar energy and medical devices.  

Prior to joining Merchant & Gould, Andrew was a patent agent at an intellectual property law firm in New York. He was also a recipient of the NIH Ruth Kirschstein National Research Service Award (NRSA) for postdoctoral studies directed to novel methods in catalytic and enantioselective organic synthesis and their application to the total synthesis of complex natural product targets. During his graduate work at The University of North Carolina, Andrew researched approaches to asymmetric synthesis using polymer supported early and late transition metal-based catalyst systems and the concept of molecular imprinting.

Andrew enjoys technical scuba diving, photography, philosophy, cycling, music and the great outdoors.
