Gilead (GILD) invented Tamiflu, the popular antiviral drug, but licensed it to Roche Holding Ltd. in 1996 (RHHBY).
Between 2001 and 2004, Tamiflu's annual sales were $200 million, which earned Gilead royalties of between 7% and 11%.
But fear of the Avian flu and a possible pandemic has prompted 30 governments, including that of the U.S., to stockpile the drug.
Gilead has launched a legal battle to wrest control of Tamiflu from Roche. If it's successful, that would be a major coup: Citigroup's Werber projects Tamiflu's sales will reach $850 million in 2005.
