Litigator turned prosecutor, Mary prepares your patents to stand up in court

Mary prepares and prosecutes US patent applications, counsels clients on strategies for increasing commercial value of their intellectual property portfolios, prepares opinions, and practices before the US Patent and Trademark Office (USPTO) in post-grant proceedings in the areas of biotechnology, pharmaceuticals, medical devices, and solid particles. Mary has been recognized as an IP Star by both Managing Intellectual Property and LMG Life Sciences. Her value-adding approach to building her clients’ IP portfolios is backed by more than a decade 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 novel and nonobvious 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 companies, research foundations, universities, and multi-national companies. She has experience with a broad range of life science technologies, including antibodies; recombinant organisms, genes, and proteins; ribozymes; RNA interference; gene therapy; virology; cell-based therapies; orthobiologics; biochemistry; protein purification; small molecule therapeutics; salt and polymorph forms; solid particles; pharmaceutical formulations; diagnostics; treatment methods; and biological aspects of medical devices.

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

Mary focused her doctoral and post-doctoral research on embryonic and fetal gene therapy 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 and adenovirus); in utero gene therapy methods in mice and nonhuman primates; catalytic RNAs (ribozymes); and lysosomal protein (acid alpha-glucosidase) 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 is involved with several Life Science organizations including SEBIO, Georgia BIO, North Carolina Biotechnology Center, North Carolina Council for Entrepreneurial Development, and BioFlorida. She has served as Chair of the SEBIO Networking Committee and was an SEBIO Early Stage Company Mentor. Mary is also a past vice-chair of the PTAB Bar Association PTAB Appeals Committee.
