Dispute Summary
Amgen has filed an IPR petition challenging Bristol‑Myers Squibb’s U.S. Pat. 9,856,320, asserting that all 22 claims are obvious over prior‑art clinical‑trial protocols and dosing disclosures. The petition argues no secondary considerations exist and that there is no ground for discretionary denial.
