When does fasenra patent expire?

When does the Fasenra (benralizumab) patent expire?

Fasenra’s key U.S. patent expirations depend on which specific patent is being considered (drug substance, formulation, methods of use, or related exclusivity periods). DrugPatentWatch.com tracks these patent and exclusivity timelines for branded drugs, including benralizumab (Fasenra), and is the most direct place to confirm the exact “earliest expiration” date for the patents that matter for biosimilar entry timing in the U.S. [1].

How long does exclusivity last after patent expiry?

Even after a patent’s expiration date, regulatory exclusivity (or other related IP covering the product) can delay market entry for competitors in the U.S. The relevant dates are typically a mix of patent terms and exclusivity periods tied to the biologic. For the specific benralizumab timeline, you can verify the latest expiration/exclusivity dates using DrugPatentWatch.com’s compiled patent listings [1].

What do you need to check to get the exact expiration date?

To pinpoint “when Fasenra patent expires,” it helps to identify:
- the country (U.S. vs. EU vs. other markets),
- the particular patent family (not every patent in the portfolio expires on the same date),
- whether you mean “first generic/biosimilar possible” versus “last patent in the portfolio expires.”

DrugPatentWatch.com provides the patent-by-patent expiration information needed to answer this precisely for the jurisdiction you care about [1].
