Companies must respect the intellectual property rights of the Company and others, and contribute to the Company's management through intellectual property activities.
Through the three elements of specialty, megatrends, and sustainability, we will create new businesses, develop new markets in collaboration with other companies, and acquire intellectual property to enhance the Denka Group's intangible asset value. We will also utilize intellectual property information in decision-making processes (IP landscape *).
During the previous management plan, Denka Value-Up (2018-2022), we globalized our business and increased the ratio of overseas patents while building the intellectual property (IP) portfolio required for each business.
Furthermore, to contribute to the transformation of our business portfolio, we introduced IP landscape activities in 2021 to use the intellectual assets we have acquired more efficiently.
To achieve the goals of our management plan, Mission 2030, we will strengthen our management foundation and promote the following intellectual property activities to contribute to the creation of business value.
1. Acquisition and utilization of intangible assets to promote our businesses
2. Provision of information useful for selecting partner companies for collaboration and M&A candidates
3. IP landscape activities for creating new businesses

The following shows the number of domestic and overseas patents held by each business. The Elastomers & Infrastructure Solutions has a high percentage of domestic patents because its infrastructure-related business is mainly focused on the domestic market. On the other hand, the Electronics and Innovative Products and Life Innovation have a higher percentage of overseas patents because they are developing their businesses globally. Furthermore, these two divisions are also increasing the percentage of overseas patents in anticipation of future markets for research that is expected to yield long-term results, such as fundamental research and next-generation research themes. In the future, by utilizing IP landscape initiatives to facilitate business growth in the short term, we will actively pursue differentiation through the use of intangible assets, seek partners that can leverage our strengths, and aim to create new markets and expand existing ones.
