Paul E. Zarek, Ph.D.

Patent Agent / St. Louis Metro Office

With nearly a decade of experience as an Examiner for the United States Patent and Trademark Office, Paul knows the inner workings of patent examination and prosecution and is able to expertly guide innovators through the IP development process.  He focuses on inventors within the biological, biopharma, and life science industries, ranging from small molecule therapeutics, biologics, medical devices, and methods of treating a wide variety of diseases.

His previous years as a USPTO “insider” means that his clients gain Paul’s comprehensive patent experience and extensive knowledge of relevant patent laws.  He diligently leads his clients from invention through the filing and prosecution of domestic and international patent applications.  Amiable and efficient, with a razor sharp focus for his client’s success, Paul is a dedicated partner and adviser with years of experience to counsel inventors and entrepreneurs alike in the field of intellectual property.

Prior to joining Harness Dickey, Paul focused his examination efforts at the USPTO on small molecule pharmaceuticals and methods of treatment, particularly immunology and cancer.  As an Examiner, he utilized his comprehensive patent experience and extensive knowledge of patent laws and regulations to determine patentability of claimed inventions.  He approved patents for major pharmaceutical companies, academic research institutions, and pro se inventors.

Paul received his scientific training at The Johns Hopkins University School of Medicine within the department of Pharmacology and Molecular Sciences. He explored the role of extracellular adenosine and the adenosine A2A receptor on T cell tolerance and regulatory T cells, using multiple state-of-the-art biological techniques, including fluorescence activated cell sorting, flow cytometry, in vivo models of cancer and T cell activation, and cell culture.

A dedicated father and family man, Paul enjoys spending time with his wife and four children, and, as a family, rooting for the Georgetown Hoyas whenever they can.
