Additionally, Paul has extensive expertise in prosecuting and investigating patents related to bioproduction methods and therapeutic formulations. He is a recognized leader in understanding the significance and challenges of bioprocessing patents from both an originator and biosimilar perspective.

The first edition focused on the new contested proceedings under the America Invents Act that year, while the second edition provides a fresh and comprehensive exploration of these proceedings. Both books examine how the proceedings interact with other aspects of patent procurement and enforcement, and deliver practical analysis and advice.
