 In March 2004, Pharmasset was willing to reveal details of its formulas on the call because it was led to believe everyone on the call would be subject to the confidentiality agreement.But the participants included Merck patent attorney Phillippe Durette, who wasn't firewalled and was in a position to turn what he heard into a potential goldmine for Merck.Durette lied about being on the conference call under oath and then Merck's legal team advised him to blame it on poor memory.
