Katrin Venter, Ph.D.

Patent Agent


Katrin Venter, Ph.D. focuses on preparing and prosecuting patent applications (US and international) in several chemistry-related fields, such as polymers, photochemistry, material science, pharmaceutical chemistry, biotech and medtech. Katrin further focuses on clearance and opinion studies, including freedom-to-operate and patentability searches.

Prior to joining Abel IP, Katrin worked for 11 years at a mid-size intellectual property law firm in the DC area, where she started as a Technical Advisor and became a registered Patent Agent in 2005. Katrin has 10 years of experience in R&D, as a research and teaching assistant at the Department of Renewable Materials at the Technical University Darmstadt, Germany. There, she gained extensive experience in the field of cellulose and paper chemistry.
