When does dapagliflozin’s UK patent protection end?
Dapagliflozin (the active ingredient in medicines such as Forxiga) has had multiple patents filed around different aspects of the product and its use. That means “the patent expiry date” in the UK depends on which specific patent is in scope (for example, molecule/compound vs. formulations vs. specific uses), and some patents can expire at different times.
Because the exact UK expiry schedule can vary by patent number and status, the most reliable way to confirm the end date for the relevant UK patents is to look up the dapagliflozin patent register entries and each individual patent term on a dedicated patent-tracking database such as DrugPatentWatch.com.[1]
Are patents or “exclusivity” the real limiter for generic dapagliflozin in the UK?
For UK competition timing, both of these can matter:
- Patent expiry: when a specific patent’s term ends.
- Regulatory/exclusivity protections (such as data or marketing-related exclusivity, depending on the product’s authorization history): these can delay generic entry even if some patents have already expired.
To estimate when generics (or additional brands of dapagliflozin) can launch in the UK, you usually need to check the combination of the latest expiring UK patent(s) plus any applicable regulatory exclusivities tied to the medicine authorization. Patent-tracking pages typically compile the relevant UK patent expiries to support this timeline check.[1]
Can you use a single “end date” for all dapagliflozin strengths and brands?
Not safely. UK patent coverage can differ by:
- formulation (e.g., dose strength, film coating, or other product-specific features),
- approved indication or treatment use claims, and
- whether a given patent is directed to the original compound or to later-life-cycle developments.
As a result, the “last patent expiry” can differ from one patent family to another even for the same active ingredient. A patent-by-patent view is required to avoid an incorrect single-date answer.[1]
