Counsel

Geng PhD, Deric X.

Dr. Geng focuses his practice on various patent prosecution and patent litigation areas, and more specifically on US and foreign patent prosecution, due diligence, prior art and patentability search, freedom to operate analysis, inter partes review and patent litigation. Dr. Geng has helped a variety of startup, mid-size and well-established clients in the chemical, pharmaceutical, biotechnology, and energy industries to obtain patent protection in the US and foreign countries. Dr. Geng's practice focus also includes Hatch-Waxman and other patent litigations for leading pharmaceutical companies.

Prior to joining the firm, Dr. Geng was a Research Investigator at the Novartis Institute for Biomedical Research in Cambridge, Massachusetts. His primary research involved discovering drug-like molecules that modulated protein targets and pathways implicated in diabetes and metabolic diseases.

From 2002 to 2004, Dr. Geng was a US Army Breast Cancer Research Foundation Postdoctoral Fellow in Dr. Samuel Danishefsky's laboratory at the Memorial Sloan-Kettering Cancer Center in New York, where he accomplished the total synthesis of anticancer agent aigialomycin D and worked as a part of a team to design and accomplish the total synthesis of fully synthetic gp120 glycopeptides as anti-HIV vaccine agents.

Dr. Geng obtained his PhD degree from State University of New York at Stony Brook in 2002, where he designed and synthesized taxoid and taxane-free anticancer agents in Professor Iwao Ojima's laboratories.
