Candesartan patent?

Candesartan (the active form) and its prodrug candesartan cilexetil have been covered by several patents over the years (covering the chemical itself, its salts, formulations, and some fixed‑dose combinations). In many major markets the core patents have expired or are near expiry, but there can still be active patents on specific uses, formulations, or combinations in certain jurisdictions.

If you want precise, current patent status, I can help you look it up—just tell me:
- Which country/region you care about (US, EU, Japan, etc.)
- Whether you want expiration dates, patent numbers, or just a quick status summary
- If you’re interested in a specific aspect (e.g., candesartan cilexetil, salts like candesartan potassium, fixed-dose combinations with hydrochlorothiazide, etc.)

Note: For anything involving freedom-to-operate or licensing, it’s best to consult a patent attorney or a patent database (USPTO, EPO/Espacenet, Google Patents) to confirm current status.
