More complicated question than you think.

In US, the basic patent for Lipitor (active ingredient- atorvastatin) expires on March 24, 2010.

The second patent covering the calcium salt of atorvastatin (Lipitor) expires on June 28, 2011.

In Europe, the basic patent for Lipitor (active ingredient- atorvastatin) expires in 2007. The second patent covering the calcium salt of atorvastatin (Lipitor) expires in July 2010.
