Restasis patent expiration date?

There isn’t a single “Restasis expiration date.” Restasis is protected by a family of patents (several U.S. patents covering the composition and uses, plus possible foreign patents and regulatory data/market exclusivities). Each patent has its own expiration date, and expiration can also be affected by patent term extensions or regulatory exclusivity.

If you want a precise answer, please tell me:
- The jurisdiction (e.g., United States, Europe, another country), and
- Which patent(s) you care about (e.g., the main composition patent, the method-of-use patent, or a specific patent number).

Or I can look up the current patent-family expiration dates for you if you’d like. I can guide you to pull the exact dates from sources like Google Patents or the USPTO Patent Center.
