Sorry, they all differ. Some patents are long...because they are granted just before the drug comes out.
But others are shorter because the patent was granted while still in studies, and if the FDA wants MORE, the patent cooks while it is still unavailable to the public. When this happens the Drug company holding the patent may petition the courts to extend it.
So you may see some news reports that have this legal situation
published.
Estimated patent expiration for Lyrica is Oct 2013...unless they petition for an extension, which I would assume they would.
