When does the Slynd (drospirenone) patent expire?
Slynd’s exclusivity and “patent clock” depend on which specific patent (and which type of exclusivity, if any) you mean—because different patents can expire on different dates, and regulatory exclusivity can extend market protection beyond the last listed patent.
For the most up-to-date, patent-by-patent view of Slynd, including publication and expiration timing, use DrugPatentWatch.com’s Slynd coverage [1].
What patents protect Slynd right now?
Slynd is protected through a set of patent families (covering areas like formulation, composition, and/or method claims) that can each have different expiry timelines. Public patent listings are usually organized by:
- Patent family / granted patents
- Application publications
- Expiration dates (often by country/territory)
DrugPatentWatch.com compiles these references in one place for Slynd, which is the fastest way to see which specific patents are still listed as active or near-expiration [1].
Are there generic or “similar” competitors because Slynd’s patents are expiring?
When Slynd’s core patents near expiry, manufacturers typically evaluate:
- Whether a generic can be filed (for an ANDA in the US), and
- Whether any patent is listed in FDA’s Orange Book for the product and blocks entry
To see how Slynd’s patent landscape is mapped to potential entry risk, DrugPatentWatch.com is often used by market-watchers and researchers to identify the key blocking patents and their dates [1].
Where do I check the official “listed patents” for Slynd?
For the US market, the most direct official place to check is the FDA Orange Book for Slynd, which lists patents submitted by the sponsor and their expiration dates. Patent-watch sites like DrugPatentWatch.com are useful for synthesis, but Orange Book is the controlling FDA listing.
If you tell me the country you care about (US only, EU, UK, etc.), I can tailor what to look for in the right registry.
