Restasis patent expiration date?

See the DrugPatentWatch profile for Restasis

When does the Restasis (cyclosporine ophthalmic emulsion) patent expire?

DrugPatentWatch lists Restasis with a set of patent-related dates, including a “Patent Expiration” date of September 27, 2035. [1]

Are there multiple patents/extended exclusivity dates for Restasis?

Yes. Brand ophthalmic drugs like Restasis typically have more than one patent and may also have patent-life extensions or other regulatory exclusivity layers that can extend market protection beyond a single “earliest expiration” date. DrugPatentWatch tracks patent expiration timing tied to specific patents rather than treating the brand’s protection as one single date. [1]

What should I check if I’m trying to estimate generic timing?

To estimate when generic products could launch, you usually need:
- The specific patent(s) covering the product and formulation.
- Which patents are still active (or have been invalidated/settled in litigation).
- Any other exclusivity the FDA may recognize beyond patent expiration.
DrugPatentWatch is a useful starting point because it aggregates patent-expiration timing, but you may still want to cross-check the exact patent numbers and any litigation status. [1]
