Recent amendments to the Pandemic and All-Hazards Preparedness and Response Act (PAHPARA) authorize HHS to study alternative economic models for the pharmaceutical business that essentially divorces research and development costs from drug prices by taking away the state-sanctioned monopolies such as exclusivity periods and patents.  Should pharma be forced to make money without patents? Or are there fixes to the patent system that could cut down the delay of entry of lower-cost generics?

In February 2023, United States Senator Elizabeth Warren penned a letter to Kathi Vidal, Director of the USPTO, asking what the Patent Office can do to blunt Merck’s use of patents to stall entry of lower-cost alternatives for Keytruda.  Unfortunately for consumers, the answer may be, not that much.

Senator Warran recently asked what the Patent Office can do about patent thickets. Yet, the courts are in the unique position of having to contend with scores of patents asserted within a single suit.  When a brand pharmaceutical company shows up with 20, 60 or 100 patents in a single suit, those challenges can be exacerbated by orders of magnitude. So, how have courts face this challenge?  Regeneron’s pending patent suit against Mylan over its prospective biosimilar for Eyelea® is an interesting example.
