Global Intellectual Property Strategies

The Tsubaki Group is globally advancing aggressive intellectual property strategies by extending patent application and acquisition of industrial property rights in Japan and overseas through an approach aimed at strengthening product competitiveness. Guided by this strategy, the number of patents held by the Group has been increasing, and as of the end of the fiscal year ended March 31, 2020, we held 838 patents in Japan and 1,209 overseas for a total of 2,047 patents.
As the Tsubaki Group has been promoting the rapid expansion of its business in China, emerging countries, and other parts of the world, the expansion of patent application efforts and thorough measures to prevent infringement of intellectual property rights in these countries is an important and ongoing task. We applied for 130 patents in these regions and increased our coordination with overseas patent offices during the fiscal year ended March 31, 2020.
Tsubakimoto Chain’s intellectual property division centralizes affairs regarding the application of industrial property rights and the prevention of infringement, while the legal affairs division has established internal regulations on managing confidential business information and spearheads Groupwide management of information on confidential technologies and business information in cooperation with the intellectual property division.
Similarly, these two divisions also cooperate on the drafting and review of contracts.

⁎ The term “intellectual property rights” refers not only to the patent rights, utility model rights, design rights, and trademark rights that come into effect through patent office procedures (collectively referred to as “industrial property rights”), but also to the rights that come into effect without the need for a procedure, namely copyrights and trade secrets (know-how).
