Dispute Summary
Amgen petitions the PTAB to invalidate Bristol‑Myers Squibb’s ’529 patent covering anti‑PD‑1/anti‑CTLA‑4 regimens for MSI‑H colorectal cancer, citing anticipation and obviousness over multiple clinical‑trial disclosures. The petition argues no secondary considerations or discretionary grounds support the patent’s validity.
