Professional Experience

As an associate at Kinney & Lange, Alexander focuses his practice on patent law, including drafting and prosecuting patent applications, conducting freedom-to-operate studies, and conducting patentability studies. Alexander has experience working with clients of all sizes, from individual inventors up to multinational corporations.

Alexander received his Juris Doctor from the University of Minnesota, magna cum laude. While in law school, Alexander was the lead articles editor for the Minnesota Journal of Law, Science & Technology. He also authored a published an article concerning the patent eligibility of certain siRNA technologies. Additionally, he worked as a research assistant for Professor Oren Gross, an internationally recognized expert in the areas of international law and national security law, to investigate international law issues related to potential applications of neuroscience and biotechnology in warfare. Alexander is also a Rule 114 qualified neutral and worked in the Community Mediation Clinic, a comprehensive mediation clinic run by the University of Minnesota and the Conflict Resolution Center.

Prior to law school, Alexander earned a PhD in molecular biosciences and a bachelor’s degree in biochemistry at Washington State University. His graduate work focused on the structural characterization and functional engineering of enzymes involved in phenylpropanoid biosynthesis in Sorghum bicolor. During graduate school, he had an active interest in science pedagogy and taught courses on bioinformatics, enzyme kinetics, and protein purification in both laboratory and lecture settings. After completing his graduate work, Alexander worked briefly in an academic laboratory investigating the Lyme disease pathogen, Borrelia burgdorferi.

In his free time, Alexander enjoys live music, playing guitar and piano, crate-digging for vinyl records, and late-night sessions of Dungeons & Dragons.
