Abstract
Comparative study of the claim number, the examination time, the inventors number and the maintenance time of granted patents in the physics technological field in China, France and Germany in 1994, conclusions as following: the patents renewal time are mainly decided by the qualities or values of patents, and these information are influenced by the patent systems of countries and the patent management capabilities of patentee, and the difference of patents renewal information have a specific expression in the physics technological field. What’s more, the average number of claim, the average examination time, the average inventor number and the average maintenance time of patents granted by China are lower than that of patents granted by France and Germany in this technological field.
This paper was published at the 2015 3rd International Conference on Material, Mechanical and Manufacturing Engineering, authors are Yongzhong Qiao and Yan Zhang.

Reason why choose patents granted in 1994 is that the legal maximum of patents protection period are 20Â years from the date of filing patents in China, France and Germany. In December 2014, the maintaining state of each patent has been determined that there is no effective patent point in time in the future uncertainty whether also continue to be valid.
