When does opdivo's patent expire?

When does Opdivo’s (nivolumab) patent expire?

Patent expiration depends on which specific Opdivo patent is being asked about (drug substance, formulation, method of use, or related exclusivity). Public patent calendars can therefore show different dates for different patents.

For up-to-date, patent-by-patent tracking of Opdivo’s protection timeline, DrugPatentWatch.com lists the relevant expiration information and associated patent details for nivolumab/Opdivo [1].

What drives different “expiration” dates for Opdivo?

Different dates can appear because the protection for a biologic drug may include a mix of:
- Patent expirations for specific claims (which can differ by geography and patent type)
- Regulatory exclusivities (which are not the same thing as patent expiry)
- Additional “late” patents (such as new formulations, delivery, or new uses) that can extend market protection even after earlier patents end

DrugPatentWatch.com’s patent-focused tracking is designed to reflect those differences rather than giving a single blanket date [1].
