Martin S. Masar III, PhD

Chicago Office

Dr. Martin Masar has varied experience in patent prosecution and litigation, with emphasis in the scientific fields of chemistry, pharmaceutical arts, nanotechnology and biotechnology. He began his career in patent law as a technical specialist and patent agent at an independent intellectual property firm. Martin has prepared and prosecuted patent applications for a number of clients from an array of technical fields, including nanotechnology-based mass spectrometry methods and apparatus, nanotechnology-based computer chip coolers, radiation therapy methods for cancer treatment, breathable polymers, fire detection systems, medicine dispensing systems and methods and dietary supplements.

Martin has experience in pharmaceutical patent litigation relating to the Hatch-Waxman Act and other pharmaceutical and cosmetic contexts, including participating in four trials, arguing motions, deposing fact and expert witnesses and preparing opinions, briefs and Paragraph IV Notice letters for more than two dozen pharmaceutical or cosmetic products. He has also been involved in antitrust and unfair competition litigations.

Martin previously served as Industrial Liaison and Scientific Officer for the International Institute for Nanotechnology, headquartered at Northwestern University. In these roles, he initiated and fostered collaborations between the Institute and corporations and universities from around the world, secured funding for the Institute through corporate partnerships and drafted grant applications and annual reports to federal and state governmental agencies.

While attending law school, Martin was a member of the DePaul Law Review. He received awards in patent law courses including the 2007 Robert Chambers Award in Patent Law and CALI Awards in Biotechnology Patent Strategies, Advanced Patent Law Seminar and Patent Law. He also received CALI Awards in Legal Writing, Evidence, Legal Profession and Pre-Trial Civil Litigation. Martin graduated in the top 5% of his class.

As part of his doctoral studies, Martin worked with Professor Chad A. Mirkin. His dissertation research related to the synthesis and development of protein mimics that were useful in catalysis and sensing applications. This work led to six publications in peer-reviewed technical journals, including Journal of the American Chemical Society and Accounts of Chemical Research. Martin received one of the 100 annual fellowships from the Multidisciplinary University Research Initiative (MURI), a division of the Department of Defense.
