What is the commercial value of gene patent?

Gene patent is the basis of developing gene-related products. The right holders of gene patents can not only make profits through patent cooperation or transfer, but also get a certain percentage of commission from the later sales income of gene drugs and other derivative products based on gene patents. The patent transfer value of a disease-related gene with important functions is generally tens of millions of dollars, and the annual sales of gene drugs developed by this method can reach billions of dollars.
