Welcome to the latest issue of Blockbuster Biologics Review, which covers the status and developments of post-grant challenges inter partes reviews (IPRs) and post-grant reviews (PGRs), patent litigations implicating blockbuster biologics, and legislative proposals related to biosimilars in Q1 2022. We will continue to monitor developments in these post-grant challenges and litigations and provide you with regular updates.
Inter Partes Reviews (IPRs) and Litigations
