Success relies on a true understanding of the scientific basis of the invention, and the ability to convey that information in a form most acceptable to each patent office. The Shimizu Patent Office prides itself on the quality of its scientific talent, the speed and efficiency of its work, and its truly international nature.

The Shimizu Patent Office is located in Tsukuba Science City, a dynamic and innovative city situated 60 km northeast of Tokyo.
