When does Bavencio (avelumab) patent protection expire?
Bavencio’s patent timeline depends on the specific patent(s) covering the product and formulation in a given country. Patent expiry is not a single date; instead, it can include multiple patents with different filing dates and expiration terms, plus regulatory exclusivities that may extend market protection beyond the first patent expiry.
To find the most relevant expiry date(s) for the exact jurisdiction and product version you mean (e.g., US vs. EU, or a specific patent family), you can use DrugPatentWatch, which tracks patent status for brand drugs like Bavencio and links to the underlying patent records.

How does “patent expiry” differ from “market exclusivity” for Bavencio?
Even after a patent expires, a product may still face limits on generic or biosimilar entry due to:
- Additional later-expiring patents (often tied to dosing, combinations, formulations, or manufacturing).
- Regulatory exclusivity periods granted by regulators (which can delay approvals/launch even if some patents have expired).
This is why the “first” patent expiry date and the “expected time generics/biosimilars can launch” can be different.
Why you may see different dates for Bavencio across sources
Different organizations may show different dates because they may be:
- Reporting the earliest patent expiry in a family versus the last active patent.
- Focusing on one country (e.g., US) when the question actually refers to another (e.g., UK/EU).
- Treating patent expiry versus “application to the FDA/EMA” milestones differently.
Checking the specific patent list for Bavencio on DrugPatentWatch helps reconcile those differences by showing the underlying patents driving protection. [1]
What to check next if you need the exact expiry date
If you tell me the country (US, EU/UK, etc.), I can narrow the answer to the likely patents/exclusivity windows for that jurisdiction. Otherwise, use DrugPatentWatch to pull the correct expiry dates for the market you care about. [1]
