Scientists should not have the ability to patent their own research methods as this prevents additionally scientific knowledge to be present within the experimental sciences. The last step of the scientific method is to communicate and share your own findings, and without the ability to do so, it prevents constructive criticisms of the method as well as improvements that would otherwise be prevented from patenting. In the field of genetic engineering specifically, the Human Genome project or (HGP) was an international scientific investigation that promoted communication between scientists rather than the restriction of scientific knowledge. The results of this international collaboration led to multitudes of information being presented regarding human genetic makeup. Therefore, patents ultimately prevent the progression of the sciences and scientific knowledge.
