When does Yervoy’s patent expire?
The specific expiration date depends on which patent family and jurisdiction you mean (for example, primary composition-of-matter patents versus later patents covering formulations, specific uses, or process claims). The information provided here does not include any patent numbers or a country-by-country timeline, so an exact “Yervoy patent expiration date” can’t be stated reliably from the available data.
What you need to pin down an exact expiration date
To determine the correct expiration date, you typically need:
- The patent number (or the patent family) you’re asking about
- The country/region (U.S., EU, UK, etc.)
- Whether you mean the earliest patent expiration, the last-to-expire patent, or the effective exclusivity date after adjustments (such as term adjustments or pediatric extensions)
How exclusivity can differ from a patent’s “headline” expiry
Even when a patent expires, additional protections may still delay market entry, depending on the jurisdiction. Those can include:
- Patent “evergreening” via related patents in the same family (different claims with later expiry)
- Regulatory exclusivity periods that are separate from patent terms
Next step: share the jurisdiction or patent number
If you tell me whether you mean the U.S. or another country (and, if you have it, the patent number or link), I can give the precise expiration date for that specific Yervoy patent and clarify which exclusivity it corresponds to.
