Oona Johnstone focuses her practice on US and foreign patent prosecution, IP due diligence, client counseling and post-grant proceedings, including inter partes review (IPR), in the areas of biotechnology, pharmaceuticals and cleantech. Her knowledge spans a wide range of technologies including RNA-based therapeutics, transgenics, antibodies, immune-modulating agents, metabolic engineering, systems and synthetic biology, and drug delivery.

Oona has experience advising clients on maximizing patent term through patent term adjustment (PTA), patent term extension (PTE) and Supplementary Protection Certificates (SPCs).

Oona additionally has experience advising clients on biosimilar/biobetter issues.

Prior to joining Wolf Greenfield, Oona was a postdoctoral researcher in the Department of Systems Biology at Harvard Medical School. Her research, focusing on posttranscriptional gene regulation, was part of a large-scale initiative to use genome-wide technologies to characterize networks of RNA-protein interactions in the developing mammalian brain.

Oona’s doctoral research on RNA helicases helped to elucidate cell biological questions related to RNA localization and translational regulation, while placing these mechanistic insights within the context of the developing embryo.

Oona has authored and co-authored publications in journals including Molecular Cell, Development, Developmental Biology, International Review of Cytology, and Annual Review of Genetics.
