Abstract Glyphosate-tolerant crop currently takes the biggest share of GM cultivation area all around the world. Thus, the cloning, expression and function of EPSPS become main focuses of modern bio-molecular breeding, and putting the function genes and transformation techniques into their own exclusive property rights by IP protection, such as patent, becomes the general developmental strategy of developed countries and bio-technology companies. The current situation of IP protection, core patent distribution and industrialization of EPSPS gene throughout the world were analyzed by retrieving data of global EPSPS gene patents and transformation events. The result shows that applications of EPSPS patents soared up in recent years and the applicants were mainly from the US, France and China etc., but most of the key technologies and industrialization were owned by international companies like Monsanto, Bayer, Pioneer Hi-bred, and Syngenta, and the initiative of certain industrial development was controlled consequently.
