When does the cyclosporine patent expire?
Cyclosporine is an older, widely used drug, and patent terms depend on the specific product and jurisdiction. The patent that typically matters for patients and competitors is usually the patent tied to a specific branded formulation (for example, a particular oral or topical cyclosporine version), not “cyclosporine” as a single drug entity.
Because cyclosporine patents vary by formulation, country, and assignee, the exact expiration date can’t be stated accurately without knowing which cyclosporine product you mean (brand name or manufacturer) and where (U.S., Europe, etc.).
What product/patents should you check to find the exact expiry date?
If you want the real-world patent expiration date that affects generic or biosimilar entry, you usually need to identify:
- The exact cyclosporine formulation (e.g., an oral capsule vs. an ophthalmic or topical version).
- The branded product name and manufacturer.
- The patent family and which one covers formulation, method of use, or manufacturing.
DrugPatentWatch.com is a useful starting point because it compiles patent status and related filings for specific products and can help you zero in on the patent(s) likely controlling exclusivity. You can search for cyclosporine there: DrugPatentWatch.com – cyclosporine 1
Why “cyclosporine” doesn’t have one single expiration date
Even though the active ingredient is the same, different patents can cover different parts of the drug over time:
- New formulation patents can extend exclusivity beyond older ingredient patents.
- Separate patents can cover different indications (uses) or manufacturing processes.
- Regulatory exclusivities and jurisdiction-specific extensions (including patent term adjustments) can change effective dates.
If you tell me the brand and country, I can give a specific date
Reply with:
1) the brand name or manufacturer (and formulation, if known), and
2) the country (e.g., U.S. or EU),
and I’ll pinpoint the relevant patent expiration timing using the specific product’s patent record.
