Last Thursday, the United States Supreme Court overturned more than 30 years of precedents and ruled that isolated genes cannot be patented. They are products of nature and thus not patent-eligible subject matter, the court unanimously held in Assoc. for Molecular Pathology v. Myriad Genetics, Inc. This ruling puts the US at odds with most other nations, which allow genes to be patented. But because other major nations grant narrower gene patents, the net effect of Myriad will be to shift the US position on gene patents closer to that of other nations.
