Patent Agent and Technical Advisor
hjacquiau@hahnlaw.com 312.637.3022


As a patent agent and technical advisor at the Chicago office of Hahn Loeser, Dr. Jacquiau assists in all aspects of the firm’s patent practice, including patent prosecution and litigation. He utilizes his scientific and patent agent background across a variety of technologies, particularly in bioengineering, biochemistry, molecular biology and microbiology.

Dr. Jacquiau received his Ph.D. from the University of Cambridge after investigating the genetic and biochemical features responsible for the biodegradation of toxic pollutants. Dr. Jacquiau earned a Master of Science in bioreactor systems after studying chemical engineering, biotechnology, genetics, fermentation optimization and kinetics, as well as upstream and downstream processes. As an undergraduate, he studied both biological sciences and the food and biological industries.

At Hahn Loeser

Dr. Jacquiau developed novel genetic tools for the creation of biosensors and became co-inventor on a U.S. patent. His work also contributed to the creation of a biotechnology company that specializes in developing biosensors for the detection and removal of environmental contaminants. Additionally, Dr. Jacquiau investigated various mechanisms that regulate cellular sensitivity or resistance to anti-cancer agents. He researched DNA rearrangements affecting cell-cycle regulation and highlighted the role of various mechanisms of protein degradation in modulating cellular response to enzyme inhibitors that are commonly used in the treatment of childhood cancer.

Dr. Jacquiau previously worked at the Lankenau Institute for Medical Research in Wynnewood, Pennsylvania, where he first developed antibodies to be used in cancer diagnostics, or research tools to validate biomarkers of breast and ovarian cancer. At the institute, Dr. Jacquiau evaluated scientific innovations and business proposals and subsequently became a business and scientific funding associate in the Department of Business Development. He contributed to the creation of a novel drug screening facility for drug target validation and drug discovery, as well as a center for the production of human antibodies to be used as medical diagnostics, or as novel therapeutics. He also collaborated with surgeons and clinicians to develop protocols for clinical trials and wrote proposals to attract funding and to promote scientific collaborations.
