Darrin W. Hopper, Ph.D., is a patent agent in Sterne Kessler’s Biotechnology & Chemical Practice Group, where he assists in the preparation and prosecution of patent applications, the formulation of invalidity, noninfringement, freedom-to-operate, clearance, and patentability opinions, and provides litigation document review support. Darrin has also been involved in inter partes review, reexamination, and interference matters. His technical areas of expertise include traditional medicinal/synthetic/organic chemistry including compound identification and the issues of drug purity, stability and bioavailability.

Prior to joining Sterne Kessler, Darrin was a principal research scientist in an international pharmaceutical company where he conducted research in the areas of infectious disease, inflammation and oncology.

Darrin received his Ph.D. in chemistry from the University of Virginia. In addition, Darrin was a NIH Postdoctoral Fellow at the State University of New York at Buffalo where he synthesized Methylphenidate analogs for the treatment of cocaine abuse. Additionally, his graduate research involved the synthesis of lysophospholipid mimics as agonists and antagonists of Lysophosphaticic Acid. Darrin received his B.S. in chemistry, magna cum laude, from the State University of New York at Oswego.
