From the MSF press release:

People across the developing world continue to die because they do not have access to life saving tmedecines. Existing treatments are are too expensive due to patent protection and needed are not being developed, as people in developing countries do not represnt a lucrative market.. Every day, MSF doctors struggle to provide treatment to patients suffering from infectious diseases such as tuberculosis and HIV/AIDS leishmaniasis and sleeping sickness.

G8 leaders have singled out innovation and Africa as two of the Priorities for the summit in Heiligendamm, and hold up intellectual property protection as the way to foster innovation. But todays system of patent protection and high drug prices as the way to finance innovation leaves the needs of millions of people across the developing world unmet.
