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.
