When does Yervoy’s patent expire?
You can’t get a single, reliable “Yervoy patent expiry date” from the information provided here because the exact expiration depends on the specific patent(s) covering Yervoy and the jurisdiction (for example, the US versus Europe), including whether those patents have different claim types, enforcement timelines, or extensions.
Why there isn’t one simple expiry date for Yervoy
Originator biologic and small-molecule products like Yervoy typically have multiple layers of IP protection, which can include:
- patents on the active ingredient or specific formulations
- patents on manufacturing processes
- additional patents that extend protection for particular uses or improvements
That means “patent expiry” can differ by patent number and by country, so users often see multiple dates rather than one clear day.
What you should look up to get the exact date(s)
To clarify the patent expiry date(s) precisely, you would normally identify:
- the country/jurisdiction you care about (e.g., United States, EU/UK, Canada, etc.)
- the exact product code and legal name used in the patent records (Yervoy could be associated with multiple related patent families)
- the specific patent(s) listed as covering the product (not just the brand name)
If you tell me your country, I can narrow it down
If you share the country/region (US, EU/UK, etc.), I can help you determine which specific Yervoy patents are likely to control and what their expiration dates are, then summarize the earliest relevant date.
