We Were Forced To Create HIV Virus To Wipe Off African Race - Dr. Robert Gallo

Unfortunately, a large part of the damage has already been done, and that among other articles has helped foster the continued existence of a completely unfounded theory based primarily on not understanding what a patent is in molecular biology. A patent on Ebola or HIV is not the same as a patent on an engine.
Whereas the engine’s patent is reserving the production of that type of engine to the patent holder, a patent on HIV or Ebola is a patent meant to specify how the virus was isolated, how the genotype was determined, and what this consensus genotype is.

In biology, you can patent things you found to concretely identify that component, potentially for use in a more complex system later. Keep in mind that you can even patent seeds obtained from cross-pollination: the patent does not mean the species was genetically modified in a laboratory.
