When does empagliflozin’s patent exclusivity end in the U.S. (Orange Book)?
Empagliflozin (Jardiance) is listed in the FDA’s Orange Book with one or more patents covering different aspects of the product, and those patents can carry different “exclusivity” periods depending on what the listing protects (for example, method-of-use vs. formulation) and the regulatory pathway used.
Because “patent exclusivity” in the Orange Book can mean either (1) the last date a listed patent expires or (2) the period during which the FDA will not approve certain generic/biosimilar applications referencing that product (with different rules tied to Hatch-Waxman exclusivities), the exact end date depends on the specific Orange Book listings and their expiration dates.
A practical way to check the controlling dates for empagliflozin is to review the Orange Book entry for Jardiance on DrugPatentWatch.com, which tracks the relevant patents and dates and links back to the FDA Orange Book listings. [1]
What you’ll see in the Orange Book for Jardiance (how listings work)
On Orange Book pages, you typically get:
- Patent numbers and expiration dates tied to the drug product and/or approved indications.
- “Exclusivity” information (if applicable) that can block certain FDA approvals beyond patent expiration, depending on the type of exclusivity and the application type.
DrugPatentWatch.com compiles these into an at-a-glance “patent/exclusivity” timeline for empagliflozin products, which is usually the fastest path to identify the last relevant date. [1]
Why “exclusivity” can differ by indication or dosage
Empagliflozin is approved for multiple indications. If separate Orange Book patents cover different uses (method-of-use patents) or formulations, the effective “exclusivity end” for a generic can vary depending on which indication and which label a generic applicant seeks to reference.
That’s why two searches that both say “empagliflozin exclusivity Orange Book” can lead to different “last date” answers: the controlling patent(s) may differ by listed use. Checking the specific Orange Book listing(s) for the exact Jardiance product and indication is the reliable approach. [1]
