Jens Grabenstein
Senior Associate

Jens advises a range of organisations including established biotech and big pharma companies. His practice covers various technological areas such as enzyme replacement therapies, vaccines, therapeutic antibodies, metabolic engineering and drug delivery. He assists clients in all stages of patent prosecution, including the initial drafting and filing of patent applications as well as representing clients at oral proceedings before examining divisions. He also has experience in defending or attacking patents in EPO opposition proceedings. He is particularly interested in the interface of patent and regulatory protection and has advised clients on paediatric extension requests and orphan market exclusivity. He frequently provides validity and freedom-to-operate opinions.

Before joining the firm in 2011, Jens spent four years working in the life sciences practice group of a global US law firm both in the US and Germany. He entered the patent profession in 2007 and was registered to practice before the United States Patent and Trademark Office in 2008, before qualifying as a European patent attorney in August 2012.

Before entering the patent profession, Jens conducted post-graduate research with a particular focus on host-pathogen interactions. He was awarded a doctoral degree in molecular genetics and microbiology from Stony Brook University (State University of New York) in 2005 for his research on microbial factors involved in the intracellular survival of Yersinia pestis in macrophages. He received the Abrahams Award for Outstanding Achievement as a Graduate Student and has co-authored several scientific articles. As a postdoctoral fellow at the NYU Medical Center, he studied the cellular signalling pathways which Mycobacterium tuberculosis exploits to inhibit efficient macrophage activation.

Jens is a native German speaker. He enjoys spending time with his family and is an avid reader. His interests include nature, gardening and photography.
