Named an "IP Trailblazer" by The National Law Journal, Dr. Tamera (Tammy) Weisser is leader of Jones Day's global patent prosecution group and has more than 25 years of experience in global patent portfolio development, management, and enforcement in biotechnology, particularly in the areas of antibodies, cell therapies, gene therapies, and diagnostics. Her practice also includes performing patent validity and freedom-to-operate analyses and conducting due diligence of patent portfolios for clients, including potential investors, acquirers, and licensees.

On behalf of BioMarin, she established a worldwide patent portfolio for Palynziq®, an FDA-approved enzyme replacement therapy for phenylketonuria treatment. On behalf of NGM Biopharmaceuticals, Tammy coordinates the global patent strategy concerning aldafermin in clinical trials for the treatment of nonalcoholic steatohepatitis (NASH), as well as the therapeutic antibodies NGM707, NGM831, and NGM438 for the treatment of cancers and tumors. She has developed IP strategies for dozens of antibody therapeutics for clients, including AbbVie, Astellas/Agensys, BMS/Celgene, Kyowa Kirin, Merck & Co., and Xencor. Commercial products for which Tammy has experience include Carvykti®, Embosphere®, Humira®, Kynamro®, Otezla®, Palynziq®, Pomalyst®, Revlimid®, and Synagis®.

In addition, Tammy has in-depth experience in inter partes review (IPR) proceedings. For example, she successfully defended AbbVie in two IPRs brought by Amgen, five IPRs brought by Coherus, and another IPR brought by Sandoz in connection with patents related to formulations for AbbVie's antibody adalimumab, marketed as Humira®, in which the PTAB denied institution of each petition.

Most recently, Tammy served on the board of governors of BIOCOM, and she is consistently recognized as a top lawyer and for her leadership and contribution within the community.
