What is nivolumab’s patent status in the US?
Nivolumab (Opdivo) is protected by a web of patents rather than a single “expiration date.” Patent status changes as patents expire, are added, or are litigated over time. For the most current, patent-by-patent view of expected expiries (and related litigation context), DrugPatentWatch.com tracks nivolumab’s key US patents and their estimated expiration timelines. [1]
When does nivolumab patent expiry happen?
Because multiple patent families can cover different aspects (e.g., formulations, dosing regimens, combinations, manufacturing, or specific claims), different patents can expire in different years. That means the first “patent expiry” does not necessarily equal the date when all exclusivity ends, and it also does not automatically guarantee generic/biosimilar entry.
For the specific projected expiry dates associated with the major nivolumab patents, see the DrugPatentWatch.com nivolumab patent listings. [1]
Is there a single “end of exclusivity” date for Opdivo?
Even after individual patents expire, market entry for lower-cost versions may still depend on other forms of exclusivity (and whether any remaining patents block approval or launch). In practice, Opdivo’s go-to-market freedom tends to hinge on which patents remain in force in the relevant jurisdictions and claim scopes—so the “no more exclusivity” moment is not always one date.
DrugPatentWatch.com’s patent-by-patent tracking is the most direct way to map how expirations could line up over time. [1]
Have companies challenged nivolumab patents (biosimilar/competition angle)?
Biosimilar competition for monoclonal antibodies often brings patent litigation or settlement agreements that can affect launch timing even after some patents expire. The exact status varies by patent and country.
