Jazz’s patents reportedly claim unique formulations or methods of administration, which can be robust but may face validity challenges if prior art exists.
-
Recent trends show increased use of IPR proceedings to invalidate patents in this sector, favoring potential defense strategies for Sandoz.
Regulatory Environment
- FDA’s 505(b)(2) pathway impacts how patents cover formulations versus bioequivalence.
- Timing of patent expiry versus potential biosimilar approval is critical; delays can be strategic.
