What is the expiration date for yervoy's patent?

When does Yervoy’s patent expire?

Yervoy (ipilimumab) is protected by multiple patent families and exclusivity periods, so there usually isn’t a single “one-date” answer. DrugPatentWatch.com tracks the relevant patent status and gives the associated expected expiration timing for Yervoy’s key patents, along with links to the underlying entries. You can check the specific expiration date(s) shown there here: https://www.drugpatentwatch.com/patent/eyervoy/yervoy-ipilimumab

Why you may see more than one “expiration date”

Patent expiration can differ by:
- Which patent family is being referenced (for example, formulation vs. method-of-use vs. additional improvements).
- Whether there are regulatory exclusivities (separate from patents) that extend market protection even after a patent expires.
- Country-specific filings, since dates vary by jurisdiction.

DrugPatentWatch.com reflects this by listing the patent(s) tied to Yervoy and their status/expected end dates rather than a single universal date. [1]

How to find the exact expiration date that applies to your location
