Dr. Carmella L. Stephens, a patent attorney with over 25 years experience, counsels a wide range of clients including biotechnology and pharmaceutical corporations as well as academic institutions on issues relating to biotech and pharmaceutical patents.  Her experience includes development and management of complex U.S. and foreign patent portfolios based on assessment of the client’s business interests.  The majority of her patent practice focuses on patent prosecution, IP due diligence and preparation of opinions relating to patent eligibility, validity, infringement and freedom-to-operate.

Dr. Stephens’ patent practice covers an array of different life science technologies including those relating to endonuclease based genome editing systems; immunobiology; diagnostic and prognostic tests based on gene expression profiles; viral based expression systems for use in gene therapy and stem cell based therapies, to name a few.

Prior to pursuing a legal career, Dr. Stephens received her Ph.D. from SUNY Stony Brook after completion of her thesis research at Cold Spring Harbor Laboratory followed by a post-doctoral fellowship conducted at Memorial Sloan Kettering Cancer Center.  Her technical background in the life sciences provides her with the ability to successfully interface with scientists to maximize protection of their intellectual property.
