Dr. Valerie L. O’Shea Murray is a patent agent in Montgomery McCracken’s Intellectual Property Department.

Valerie focuses on the preparation and prosecution of domestic and foreign patent applications. She provides litigation support in areas such as due diligence, freedom-to-operate, patentability analyses, and invalidity and non-infringement analyses. Valerie is experienced in chemical biology, enzymology, protein and nucleic acid biochemistry, biophysics, structural biology, and cellular biology.

Prior to joining Montgomery McCracken, Valerie worked at a boutique Intellectual Property firm based in Washington D.C.

Prior to working as a patent agent, Valerie was a NIH NRSA Postdoctoral Research Fellow for the department of Molecular and Cell Biology at University of California, Berkeley where she researched elucidating mechanisms of ATPase motors and switches involved in DNA replication initiation under Professor James Berger. Her research continued with Berger’s lab through its move to Johns Hopkins University’s department of Biophysics and Biophysical Chemistry, where she then became the Senior Research Specialist of her department.

Valerie conducted graduate research under Sheila David for the Department of Chemistry at the University of Utah, which consisted of mechanistic and structural investigations of a DNA repair Glycolase, MutY. This research exhibited that MutY utilizes a similar mechanism to retaining glycosidases for repairing oxidative DNA damage.
