Previous Work

Prior to joining Arent Fox, Yichen worked as both a Patent Attorney and a Patent Agent for a boutique IP firm. There he worked on patent prosecution in chemical, pharmaceutical, nutritional, and food sciences and patent litigation, including Hatch-Waxman litigation and IPR matters. He has also worked at another boutique IP firm as a Technical Advisor on Hatch-Waxman litigation and opinion work.

Yichen performed his doctoral research at the University of Kentucky and obtain his Ph.D. in Pharmaceutical Sciences, which is an interdisciplinary area between chemistry and pharmacology/biophysics. Yichen’s doctoral research includes synthesis and characterization of model compounds, spectroscopic studies of peptide folding in organic solvents, MD simulation for molecular conformation and solvation, and construction of mathematical model to predict drug permeation across model membrane.

Before entering the legal world, Yichen also worked as a scientist at Coldstream Laboratories, Inc., where he was responsible for developing lyophilized/sterilized injectable formations, and as a summer intern at Abbott Laboratories (now AbbVie Inc.).
