Simvastatin paten?

Do you mean the patent status of simvastatin (the drug itself) or a specific patent number/country? I can help clarify, but I’ll need a bit more detail.

General point:
- The core patent protection for simvastatin has expired in many major markets, and generic versions are widely available.
- Some patents may still cover specific things like salt forms, particular formulations, dosing regimens, or combination products in certain jurisdictions. Those can extend protection in those places even if the core patent is gone elsewhere.

If you want precise status, tell me:
- The country or region (e.g., US, EU, UK, Canada, Australia, etc.)
- Whether you want expiring dates, patent numbers, or just a yes/no on whether any active patents exist

I can then guide you to the best sources (Google Patents, USPTO Patent Center, Espacenet, WIPO PATENTSCOPE) or summarize the current status for that market. Note: for legal decisions, consult a patent attorney.
