Gaby is sought out by innovator and generic pharmaceutical companies world-wide for her insights and knowledge of intellectual property and Hatch-Waxman law.
Gaby counsels biopharmaceutical clients from around the world in all areas of patent procurement, including domestic and foreign patent preparation and lifecycle management strategies. Gaby also counsels clients in IP due diligence evaluations for raising and investing in growth capital, executing strategic partnerships and M&A transactions, and going public. Gaby practices primarily in the fields of biotherapeutics, small molecules, biologics, immunotherapy, antibody technologies, microbiome-based technologies, synthetic biology, DNA amplification/PCR, diagnostics, vaccines, viral vectors and drug delivery.
Capitalizing on her extensive generic pharmaceutical expertise, Gaby is uniquely qualified to evaluate complex innovator IP portfolios from a generic perspective, including method-of-use claim coverage relative to the product label, Orange Book patent listing and data exclusivity, 505(b)(2) strategies, labeling carve-outs, and Patent Term Extensions.
Gaby has rendered more than a thousand invalidity, non-infringement, freedom-to-operate, and patentability opinions in the following areas among others: small molecules; polymorphs; crystal forms and salts; chemical synthesis; agricultural chemicals, pharmaceutical formulations, including oral dosage forms and parenterals; transdermal patches; ophthalmics, creams, gels, suspensions, nasal and oral inhalation forms, pharmacokinetics, nucleic acids, medical devices and therapeutic antibodies.
In addition, Gaby has strong experience in biopharmaceutical Inter Partes Review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB).

The book provides a fresh and comprehensive exploration of patent office litigation proceedings, including how the proceedings interact with other aspects of patent procurement and enforcement, while delivering practical analysis and advice.
In addition to maintaining a vibrant practice, retaining and advancing female lawyers is important to Gaby. She is a member of the firm’s Diversity & Inclusion Committee as well as one of the organizers of “INSPIRED by the Women of Sterne Kessler," an affinity group designed to engage female attorneys through participation in a variety of programs that support personal and professional development.

Gaby is a sustaining member of the Women’s Bar Association of the District of Columbia.
