Kristy Markos, Ph.D.

Registered Patent Agent


Dr. Markos is a registered patent agent in the firm's Biotechnology/Chemical Group, where she aids in the preparation and prosecution of U.S. and foreign patent applications, drafts non-infringement and invalidity opinions, conducts freedom-to-operate, due-diligence, and pre-launch clearance and patentability searches, prepares ANDA notice letters, detailed statements, and patent certifications, and provides litigation support.  Dr. Markos's technical areas of expertise include immunology, oncology, tumor immunotherapy, biochemistry, and molecular and cellular biology.

Prior to joining Sterne Kessler, Dr. Markos completed a postdoctoral research fellowship at the National Cancer Institute, NIH.  Her research involved the use of adoptive immunotherapy to study the role of apoptosis in cancer progression and tumor escape.

Dr. Markos's graduate research focused on the role of opioids in immune system development and function.  Her studies revealed that opioids skew T helper cell development towards a type 2 phenotype leading to an asthmatic profile and susceptibility to infections.

Dr. Markos was a recipient of the NIH Fellows and Research Excellence Award, pre-doctoral and post-doctoral training grants from the NIH, a doctoral fellowship from The George Washington University, and a travel award from the Society on Neuroimmune Pharmacology.
