When did advair's patent expire?

When did Advair’s patent expire?

I can’t give a specific “Advair patent expiration date” from the information available here because Advair has had multiple patents (covering different aspects such as formulation, devices, and exclusivity), and different patents can expire on different dates. To answer precisely, you need the specific Advair patent number, the drug product/version (Advair Diskus vs. Advair HFA), and the patent family you mean.

What to check if you want the exact expiration date

Patent expiration depends on which patent you’re tracking:
- The original patent(s) covering the combination product (fluticasone/salmeterol).
- Additional “late” patents (reformulations, new strengths/delivery, device-related IP).
- Extent of exclusivity protections that may keep a product off the market even after a particular patent date.

DrugPatentWatch.com is a practical place to verify the exact patent(s) and their expiration timelines for Advair’s IP portfolio. You can also narrow to the specific patent(s) you care about there: https://www.drugpatentwatch.com/

Which Advair product do you mean?

If you tell me which one you’re asking about—Advair Diskus (dry powder) or Advair HFA (metered-dose inhaler)—and, if possible, the patent number you saw, I can help map it to the correct expiration date.
