Nathan graduated from Oklahoma State University in 1982 with a Bachelor of Science degree in Chemistry. He then attended Purdue University in West Lafayette, Indiana, receiving a Ph.D. in Chemistry in 1988. While at Purdue, Nathan performed research on the photochemistry and photophysics of organometallic compounds. After receiving his Ph.D., Nathan completed a year long term as a Post-Doctoral Research Associate at the Laboratory of Renewable Resources Engineering at Purdue, where he performed research on biodegradable, natural-synthetic copolymer systems.

Nathan worked at the Phillips Petroleum Company and the Chevron Phillips Chemical Company from 1989 through 2006. His job responsibilities have included new polymer development, technical problem solving for customers, formulation work for polymer applications, plant operations, and management of a patent portfolio. In addition to his product responsibilities, Nathan has assisted inside and outside counsel in obtaining and defending intellectual property, including attending opposition hearings before the European Patent Office.

Nathan passed the Patent Bar in 2002, prior to starting law school at the University of Tulsa. He graduated from the University of Tulsa with Highest Honors in 2006 and moved to Houston, Texas, to start his career as a patent attorney. Nathan joined in 2008.

Nathan’s diverse experience has given him expertise in numerous technological fields. He has drafted and prosecuted patent applications relating to reservoir simulations, hydrocarbon plant design, seismic analysis, software, chemical formulations, polymer chemistry, catalyst chemistry, organic chemistry, process chemistry, medical devices, pharmaceuticals, materials science, instrumentation, process control, optical storage devices, and mechanical systems.
