No 12-year reference-product exclusivity is listed in the Purple Book, and the reference product was first approved Jun. 30, 2006 — before BPCIA (March 23, 2010), so any 12-year exclusivity has long expired.
Marketing-entry ceiling (litigation risk)
Patents do not gate FDA licensure of a biosimilar — FDA licenses biosimilars (full or carved label) without adjudicating any patent. These are a practical marketing-entry ceiling resolved in the § 262(l) patent dance and ordinary litigation. A formulation/compound patent caps practical skinny entry via litigation (Regeneron v. Mylan); a method-of-use patent is carveable and gates nothing.
Latest formulation/compound patent 12209121(composition)· AI-discovered, not Purple-Book-listed · relevance 80/100. This caps practical skinny-label entry; it does not move the licensure floor above.

Approved Biosimilars
Disclaimer: Identifying an available carve-out is not a prediction that FDA will approve the particular carved label, nor that marketing it is free of infringement risk. For biologics, availability turns on exclusivities, not patents: FDA licenses a biosimilar (full or carved label) without adjudicating any patent, and patent disputes run through the § 262(l) patent dance and ordinary litigation, outside this availability view.
