Overview

Justin O. Ehresmann, Ph.D., is a partner in Lewis Roca‘s Intellectual Property practice group. Clients turn to Justin for his knowledge of OLEDs (organic light-emitting diodes), solar cells, fuel cells, microstructures, polymers, pharmaceuticals, and catalysts. Of particular interest to Justin are chemical production and new catalyst development.

Justin has extensive research experience relating to heterogeneous catalysis, inorganic chemistry, solid state nuclear magnetic resonance spectroscopy, computational chemistry, microporous materials, and zeolites. He is co-author of numerous scientific publications in leading Chemistry journals (detailed below).

Justin received his Ph.D. in Chemistry and his undergraduate degree in Environmental Studies from the University of Southern California, enabling him to offer a unique skill set to biotech and chemical firms in need of legal counsel. He serves as an adjunct faculty member of the Environmental Studies Program at the University of Southern California. Justin’s interests include mountain biking, surfing, paddle boarding, and restoring classic cars.

Personal Approach

Justin enjoys working collaboratively with clients to solve complex problems. His calm, patient, and reassuring demeanor inspires confidence and ensures that careful deliberation will lead to sound decision-making.

Justin’s ability to pivot and adapt in situations is an ideal asset in the ever-changing IP world. His clients value his depth of understanding of the science and technology impacting their business and his expert guidance in crafting legal and IP portfolio strategies.
