Dr. Jennifer Chheda has more than 25 years of experience in procuring and enforcing patents relating to biologics and small molecules, such as gene therapy, RNA (ribonucleic acid) therapeutics, antibodies, antibody drug conjugates, cell-based therapies (e.g., CAR-T cells), vaccines, and enzyme replacement therapy. She has developed, implemented, and managed worldwide patent portfolios covering commercial biologics and pharmaceuticals. Jennifer has worked with pioneers developing vaccines, such as a universal influenza virus vaccine, virus-based cancer vaccines, and products in development such as clinical candidates.

Jennifer's experience also includes patentability, invalidity, noninfringement, freedom-to-operate, and inventorship analyses and conducting due diligence for potential investors, acquirers, and licensees, such as venture capital firms, biotechnology companies, and pharmaceutical companies. She advises clients regarding biosimilars and the Biologics Price Competition and Innovation Act (BPCIA).

Jennifer has coordinated worldwide litigations and invalidation proceedings to ensure consistency between the litigations and proceedings. She has provided strategic advice regarding invalidity and infringement contentions. Jennifer's experience prosecuting patent applications globally has proved to be beneficial in the development of arguments relevant to non-U.S. jurisdictions in global proceedings. She also has provided strategic advice to clients regarding Patent Trial and Appeal (PTAB) proceedings, such as inter partes review, interferences, and reexaminations, and other post-grant proceedings, such as oppositions. Her scientific background is an asset in working with experts to develop reports and to prepare them for depositions and trial. Jennifer has worked on trade secret and patent cases.

In addition, Jennifer has drafted and negotiated intellectual property agreements, including license, sponsored research, and development agreements. She has provided IP advice in the context of M&A transactions and has advised clients such as AbbVie, REGENXBIO, and Celgene in IP-related transactions.
