Johnson & Johnson, which holds patents on three key new HIV drugs desperately needed throughout the developing world, has so far refused to license these patents to the Medicines Patent Pool. The Pool has been set up to increase access to more affordable versions of HIV drugs, including fixed-dose combinations that include multiple medicines in one pill, and to develop much-needed pediatric HIV drugs. The Pool would license patents on HIV drugs to other manufacturers and the resulting competition would dramatically reduce prices, making them much more affordable in the developing world. However, since the Pool is voluntary it will only work if patent holders like Johnson & Johnson choose to participate.
