Even better is that the patent expires March 27.
May not be so.
Here is an update I found from the original article that has been referenced on Wikipedia, BNET and many other high authority trusted sources:
The fight between Pfizer and Teva escalated June 15 through July 13, 2011 as the 12 day bench trial took place. Teva was shot down in it’s hopes to put a generic Viagra on the market.
Pfizer’s patent stands solid until 2019. There are pages and pages devoted to the procedural history of the case, which began in March 2010 when Pfizer Inc. sued Teva Pharmaceuticals after Teva gained tentative approval from the Food and Drug Administration to market a generic version of Viagra.
"We are pleased that the court recognized the validity and enforceability of our Viagra patent for the treatment of erectile dysfunction," said Amy Schulman, executive vice president and general counsel for Pfizer, in a statement. "Protecting the intellectual property rights of our innovative core is critical, and Friday's court decision acknowledges Teva's clear violation of our patent rights."
