When will yervoy's patent expire?

Yervoy (ipilimumab) is a bit tricky because “patent expiry” depends on which patent and which country, since biologics typically have multiple patents with different expiration dates (composition, formulation, methods of use, etc.).

That said, for the original approvals of Yervoy (US), the broad patent protection is generally understood to extend into the 2020s, and the last major exclusivity-related protection in the U.S. is widely cited around 2026 (often tied to the combination of patent terms and regulatory exclusivity).

To give you an exact date, tell me:

1. Which country (US, EU, UK, etc.), and
2. Are you asking about patent expiration, or regulatory exclusivity/market exclusivity (sometimes people mean one when they ask the other)?

If you reply with the country, I can narrow it down to the most relevant dates.
