A prosecutor and former litigator preparing your patents to stand up in court

Mary counsels clients on strategies for increasing commercial value of their intellectual property portfolios, prepares and prosecutes patent applications, manages international patent portfolios, performs diligence investigations, prepares opinions, and advises clients on IP transaction provisions in the areas of biotechnology, pharmaceuticals, and medical devices. Mary has been recognized as an IP Star by Managing Intellectual Property and as a US Life Sciences Star for Intellectual Property by LMG Life Sciences. Her value-adding approach to building her clients’ IP portfolios is backed by more than 15 years prosecuting and defending life science patents before the USPTO and several US district courts. Using her unique combination of experience, Mary identifies and seeks protection for aspects of technologies that otherwise may have gone overlooked and works closely with clients to align their IP portfolios with their company’s business goals.

Mary uses her value-adding approach to life science technology at any stage of development—from early discovery to block-buster product—and for any-sized life science business. She works with emerging startups, publicly-traded US companies, research foundations, and multi-national companies.

Mary leverages her litigation experience to reinforce her client’s IP portfolios. Her experience includes preparing and defending fact and expert witnesses at deposition; preparing expert discovery; drafting pleadings, motions, and briefs; participating in Markman proceedings and trials. Mary was also an attorney of record for amicus briefing before the district and Federal Circuit courts in the Myriad case.

Mary’s expertise in counseling gene therapy clients is backed by hands-on experience in the field. Her doctoral and post-doctoral gene therapy research involved investigated AAV therapies for the prevention and treatment of Pompe disease and other inherited metabolic and muscular disorders, and immunological considerations related to gene therapy. During the course of her research, she was involved in the clinical trial testing of the Myozyme® drug product. Mary also investigated murine embryonic stem cell transduction and differentiation; production, purification, and quantification of recombinant viral vectors (adeno-associated virus (AAV) and adenovirus); in utero gene therapy methods in mice and nonhuman primates; catalytic RNAs; and recombinant protein production, purification, and characterization. She was awarded post-doctoral funding from the National Institutes of Health and several pre-doctoral fellowships from the American Heart Association for her research.

Prior to joining McNeill Baur PLLC, Mary practiced as an attorney for over 9 years in the Atlanta office of Finnegan, Henderson, Farabow, Garrett & Dunner, LLP. Prior to that, Mary also gained life science patent preparation, prosecution, and interference experience working as a summer associate and law clerk at several intellectual property boutique firms throughout the Southeast.

Mary has been involved with several Life Science organizations including SEBIO, Georgia BIO, North Carolina Biotechnology Center, North Carolina Council for Entrepreneurial Development, and BioFlorida. She has also served as Chair of the SEBIO Networking Committee and as an SEBIO Early Stage Company Mentor. Mary is also a past vice-chair of the PTAB Bar Association PTAB Appeals Committee.
