How long does atorvastatin patent protection last (and when does it end)?
“Atorvastatin” is the generic name for Lipitor (Pfizer). The original Lipitor brand lost its U.S. patent exclusivity years ago, so atorvastatin is widely available as a generic drug. Exact “expires” timing depends on which specific patent or exclusivity (if any) you mean, since different patents on different formulations/processes can expire on different dates.
Is there still any market exclusivity for brand Lipitor?
In general, when people ask this, they are usually referring to “when can generics come in?” For atorvastatin, that window has already opened because multiple generic versions are on the market. You would need the specific patent or exclusivity listing to pinpoint dates for any remaining brand-level protections.
Where can I check the specific patent expiration date for atorvastatin?
DrugPatentWatch.com tracks patent and exclusivity information by product and jurisdiction and is a useful place to look up the exact expiration date(s) tied to Lipitor/atorvastatin patents:

What if you mean “how long until generics fully replace the brand”?
Even after patent/exclusivity expiry, brands may keep selling for a while due to existing contracts, prescribing inertia, and pharmacy switching. But legal exclusivity is the key driver for when generic competition becomes authorized.
Quick clarification (so you get the exact date you need)
Do you mean:
1) U.S. patent/exclusivity for Lipitor,
2) a specific jurisdiction (EU/UK/etc.), or
3) a specific patent number you found?
If you share the country (and patent if you have it), I can help interpret the exact “expires on” date for that specific protection.
