Basic stance on intellectual management

The Terumo Group strives to create intellectual property that will help strengthen its competitiveness. In doing so, we establish a priority for allocating resources, based on R&D and business strategies. Development directions are considered and intellectual property portfolios are built from a strategic perspective. In this perspective, development and intellectual property departments initiate development activities by collaborating in identifying other companies’ patents and the characteristics of their products and services. As we expand our business operations globally, we are strengthening cooperation with overseas Group companies to further the effective application of the Group’s intellectual property and taking steps to improve our management of intellectual property risk.
