Pfizer
Seeking to Extend Lipitor Exclusivity To 2016
March
26, 2008--Pfizer
filed a suit against Ranbaxy Laboratories, claiming Ranbaxy’s
generic Lipitor would infringe two patents covering the process
for making Lipitor that do not expire until 2016. Pfizer has asked
for a court order that would ban Ranbaxy from making, selling, or
importing generic Lipitor until that time. Lipitor (atorvastatin)
brought in $12.7 billion in 2007, about 26% of Pfizer's total, but
faces generic competition in March 2010. MarketWatch
