David J. Zelner
Registered Patent Attorney
David J. Zelner’s practice at McHale | Slavin focuses on patent prosecution, and advising clients on patent portfolio strategies. Mr. Zelner has an advanced degree in cell biology in addition to a law degree and specializes in biotechnology.
Prior to pursing his legal degree, Mr. Zelner spent over seven years in the research laboratories at Northwestern University Medical School, Chicago, Illinois, in the Department of Urology developing technical experience in a variety of cellular and molecular biology related technologies. In support of multiple NIH-funded projects, Mr. Zelner conducted research developing novel prostate cancer treatment strategies and identifying prostate cancer markers, including the development of advanced prostate cancer screening tools. Mr. Zelner also performed research examining the role of TGF-β in prostate cancer and the use of this growth factor as a target for gene therapy and immunotherapy. Additionally, Mr. Zelner conducted research in the area of molecular mechanisms of neuropathic erectile dysfunction and the neural control of prostate development and function.
