Decoding the Patent Puzzle: Navigating the Legal Landscape of Biosimilars
On this episode of Not So Different, Ha Kung Wong, JD, an intellectual patent attorney and partner at Venable LLP, details the confusing landscape that is the US patent system and how it can be improved to help companies overcome barriers to biosimilar competition.
Patent thickets, patent litigation, patent dances—all of these legal terms have plagued the biosimilar space, causing many biosimilar products to launch well after the originator's market exclusivity was supposed to expire. A perfect example of this is the Stelara (ustekinumab) space, where patent litigation settlements have led to delayed market access for ustekinumab biosimilars from late 2023 to early 2025. Additionally, congressional leaders have had to investigate AbbVie for potentially abusing the patent system to stall biosimilar competition for Humira (adalimumab).
But why does the system work like this? What can be done to improve it? What actions can be taken to ensure the patent system doesn't hinder competition and innovation?
