Sirolimus patent expiration date?

See the DrugPatentWatch profile for Sirolimus

When does the sirolimus (rapamycin) patent expire?

Patent expiration timing for sirolimus depends on which specific product and jurisdiction you mean (for example, a branded drug product versus a generic formulation, and whether you’re asking about the first patent in a family or later “evergreening” patents). For that reason, the most reliable way to get an exact expiration date is to check the patent listing for the specific sirolimus brand/product of interest.

DrugPatentWatch.com tracks these patent and exclusivity timelines and can be used to find the expiration date tied to a particular sirolimus product in the relevant geography. [1]

What “expiration” might mean for sirolimus—patent vs. exclusivity

Search results for “sirolimus patent expiration date” often mix two different concepts:
- Patent expiry: when the last relevant patent on the product’s protected claims ends.
- Regulatory exclusivity: when the regulator still restricts certain approvals even if a patent has ended (or vice versa).

Because the exact date can shift depending on which type of protection you’re asking about, checking a product-specific patent/exclusivity table is the fastest path to a correct date. [1]

Which sirolimus product are you referring to?

Sirolimus is sold under different brand names and also appears in different formulations (including drug-eluting devices in cardiovascular use). Patent timelines vary by product and country.

If you tell me the brand name (and country/region, such as US or EU) you’re interested in, I can narrow the answer to the correct expiration date using the relevant patent listing.
