When does the patent for dupixent expire?

See the DrugPatentWatch profile for dupixent

When does Dupixent’s patent protection expire?

I can’t give a specific expiration date from the information available here, because patent terms for Dupixent depend on which particular patent (and country/region) you mean. Different patents covering different aspects of Dupixent (for example, composition, formulation, or specific uses) can expire on different dates, and some terms can also be extended by regulators in certain jurisdictions.

Which patents matter for Dupixent expiration dates?

For Dupixent (dupilumab), “patent expiry” usually refers to the end of protection for one or more of these:
- the original compound/composition patents
- formulation or delivery-device related patents
- patents covering specific indications or dosing regimens

Because those are separate legal assets, the practical date when biosimilar or competing products can enter may be later than the earliest theoretical patent expiry, depending on what remains protected and what regulatory exclusivities apply.

What should you check to get the exact date?

To pin down the correct expiration date, you need:
- the jurisdiction (US, EU, UK, etc.)
- the patent number or application family you care about
- the relevant claims scope (compound vs. use vs. formulation)

If you tell me the country (for example, “US” or “EU”) and whether you mean first generic/biosimilar market entry or the legal end of the main patents, I can narrow the answer to the right kind of expiration date.
