Dr. Martin Masar has varied experience in patent litigation and prosecution, with emphasis in the scientific fields of chemistry, pharmaceutical arts, nanotechnology and biotechnology. Marty’s recent focus and experience has been in pharmaceutical patent litigation relating to the Hatch-Waxman Act and other pharmaceutical and cosmetic contexts, including participating in more than half a dozen trials, arguing motions, deposing fact and expert witnesses, and preparing opinions, briefs and Paragraph IV Notice letters for more than three dozen pharmaceutical or cosmetic products. He has also been involved in trademark, antitrust and unfair competition litigations.

Marty has authored a number of articles and advisories related to pharmaceutical patent litigation.

Marty began his career in patent law as a technical specialist and patent agent at an independent intellectual property firm. He 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.

While attending law school, Marty 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. He graduated in the top 5 percent of his class.

As part of his doctoral studies, Marty worked with Professor Chad A. Mirkin at Northwestern University. 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. Marty received one of the 100 annual fellowships from the Multidisciplinary University Research Initiative (MURI), a division of the US Department of Defense.
