Gilead emerges victorious in HIV drug patent lawsuit against US government.

A federal jury in Delaware has ruled that the US government does not have an ownership claim to lucrative drugs to prevent HIV that are sold by Gilead Sciences. The verdict marked a defeat for the government and activists who have pushed it to more aggressively assert its financial and legal rights to medicines developed with the help of public funding. The legal dispute centered on who devised the idea of using a Gilead medication for people at high risk of contracting HIV, which causes AIDS.
