Professional Profile 

With extensive knowledge in complex chemistry, Jane advises clients in life sciences, with a particular focus on small molecule pharmaceuticals. She has a deep understanding of the entire lifecycle of product development and aids her clients in protecting innovations from the initial discovery and testing through all later stage drug development, including protection for specific formulations and platform technologies. Through her extensive network of global contacts, she has strategically helped her clients build commercially valuable worldwide patent portfolios in over 50 countries and regions. Jane is also highly skilled in patent appeal and reexamination in front of the Patent Trial and Appeal Board. Beyond patent practice, she has extensive experience in IP due diligence connected to licensing and financing transactions, patent landscape, infringement and invalidity analyses, product clearance, and general IP strategy.

Jane advises and counsels a diverse range of clients from publicly traded companies, venture-funded start-ups, research institutions, to individual inventors. She has worked on numerous technologies, including a variety of pharmaceutical inventions for treatment of obesity, metabolic syndrome, cancers, idiopathic pulmonary fibrosis, bacterial infections, and liver diseases, as well as liposome delivery technologies. Outside of small molecule pharmaceuticals, Jane also manages portfolios involving next-generation sequencing applications, flowcells and microfluidic devices, polymer materials, medical devices, and aesthetics and personal care products. She also advises foreign internet and media clients on matters related to copyright protection, enforcement and data privacy.

Jane obtained her doctorate in organic chemistry at Pennsylvania State University, where her research concentrated on the design and synthesis of small molecule chiral ligands for transition metals catalyzed asymmetric reactions. Prior to joining Knobbe Martens, she worked as a patent agent in an IP boutique in New Jersey.
