When does the dupilumab (Dupixent) patent expire?
Dupilumab’s key U.S. patent expirations depend on which specific patent(s) you mean (drug substance, formulations, dosing regimens, and manufacturing/process patents can each carry different end dates). DrugPatentWatch tracks these by listing the relevant patent numbers and their scheduled expiration dates for dupilumab. A dedicated page for dupilumab is available here: DrugPatentWatch – dupilumab (Dupixent).
Are there different “expiration” dates: patent vs. exclusivity?
Yes. Even after patent expiration, markets can stay protected by regulatory exclusivity (and vice versa). Patent expiry dates can be earlier or later than exclusivity-driven barriers depending on the jurisdiction (for example, U.S. patent terms vs. FDA regulatory exclusivities). To map the relevant “earliest possible generic/biosimilar entry” date, you need to check both (1) the listed patent expiration dates and (2) whether any regulatory exclusivity still applies.
What determines the “earliest entry” for biosimilars/generics of dupilumab?
For dupilumab (a biologic), entry timing usually hinges on:
- the last expiring patents listed for the product (or specific claims), and
- whether any exclusivity remains in the relevant country,
as summarized by patent-by-patent listings on DrugPatentWatch: DrugPatentWatch – dupilumab (Dupixent).
Which country’s patent expiration date do you need?
Patent expiration dates vary by country and by which patents were filed there. If you tell me the jurisdiction (U.S., EU/UK, or another country) and whether you mean “first patent expiry” or “last-to-expire,” I can point you to the exact dates shown in the relevant listings.
