The Kikkoman Group aggressively seek patents for inventions, which are determined to greatly contribute to our business by registering it as a patent, with a purpose of exclusively executing it, thereby aiming at acquiring such rights. In addition, if we determine that patent registrations by other companies would greatly limit the execution of such rights, we may make a defensive patent application to stop other companies from registering such patents.
Change in number of patents owned by the Kikkoman Group in the past five years is as follows.
With regard to patents owned by the entire group, we are executing the periodical review every year for inventory, etc. regarding whether maintaining or discontinuing the rights and are maintaining the quality of intellectual properties.
