Sterne Kessler’s Christopher Gallo, Ph.D., and Pratibha Khanduri, Ph.D. examined the battleground surrounding follow-on biopharmaceutical patents, discussing strategies for obtaining these patents and approaches to defending and challenging them before the PTAB and in district court litigation.

The session explored the ongoing debate as these patents face criticism as “patent thickets” that delay low-cost competitors. The underlying follow-on research regularly delivers significant public health benefits, including optimized drug delivery systems, repurposed life-saving indications, and improved dosing regimens.

Attendees gained insights into navigating this complex landscape, which requires patent owners and challengers alike to understand competing operational strategies, emerging trends, and the rapidly evolving judicial environment.
