Value Creation

NOF's Intellectual Property

This is a image related to Value Creation

To create new value in the three fields of Life/ Healthcare, Environment/Energy, and Electronics/IT, the NOF Group utilizes the IP landscape (IPL) to advance the development of new products and technologies while actively pursuing the acquisition of intellectual property rights.
We also respect intellectual property rights, along with putting our efforts into talent development.

Status of applications in the three prioritized business fields

In the Life/Healthcare, Environment/Energy, and Electronics/IT fields, we formulate intellectual property strategies based on management strategies and acquire the necessary rights. We also recognize that investment in intellectual property is an initiative for medium- to long-term value creation, and will link intellectual property to business domain expansion and market creation.
Currently, the number of overseas patents we hold in the Life/Healthcare field has been growing in line with the expansion of our global operations.

This graph shows the number of domestic patents held by NOF Corporation by fiscal year. The breakdown of domestic patent holdings is as follows: in the Life & Healthcare field, 643 patents in FY2022, 666 in FY2023, 674 in FY2024, and 675 in FY2025; in the Environment & Energy field, 281 in FY2022, 271 in FY2023, 275 in FY2024, and 255 in FY2025; in the Electronics & Information field, 274 in FY2022, 286 in FY2023, 283 in FY2024, and 283 in FY2025; and in other fields, 6 in FY2022, 5 in FY2023, 5 in FY2024, and 3 in FY2025. The totals are 1,204 patents in FY2022, 1,228 in FY2023, 1,237 in FY2024, and 1,216 in FY2025.

Based on our corporate philosophy of “contributing to humanity and society as a corporate group that creates new value through the power of chemistry, from the biosphere to outer space,” we work to create new businesses by actively promoting open innovation and the discovery of promising topics both inside and outside the Company.
Centered on the research divisions of the NOF Group, including the Advanced Technology Research Laboratory (current Health Science Research Laboratory and Material Science Research Laboratory)*, we promote the development of new products and technologies through joint and commissioned research with industry, academia, and government, as well as acquiring the effective rights to these products and technologies.
In addition, we offer invention rewards for patents that make a significant contribution to the Company’s profits. By increasing incentives for inventors, we are working to increase motivation toward producing inventions that contribute significantly to profits.

The Advanced Technology Research Laboratory has been abolished.

Utilization of IPL

In activities such as application exploration, search for co-creation partners, and research theme exploration, NOF actively utilizes IPL, with the Corporate R&D Division, laboratories of each business division, and the IP Department working together. We have established standardized analysis flows for the purpose of investigations, and provide information that contributes to identifying the direction of R&D and searching for new applications and co-creation opportunities, by visualizing trends in technologies, competitive dynamics, and the potential of application areas. We also hold IPL liaison meetings attended by senior personnel from the research and IP departments to decide on investigation policies and manage progress, thereby boosting collaboration between IP strategy and research strategy. Through these activities that promote the utilization of IPL, we aim to improve research efficiency in each division and shorten the time required for commercialization, thereby accelerating the development of new applications and new products, as well as pioneering new markets, leading to enhancement of corporate value.
We are also promoting the utilization of IPL through enhanced internal training. In addition to basic training on searching and patent analysis, we provide training on analysis tools such as data visualization and text mining, supporting the improvement of skills of researchers.

Expansion of human resources for intellectual property

We hire qualified patent attorneys and provide support for the acquisition of patent attorney qualifications to enhance the expertise of personnel working in this area. We also provide training on intellectual property to inventors in order to raise the level of intellectual property throughout the Group.

Response to risks

In order to respect the intellectual property rights of others and avoid disputes, we conduct regular patent searches to ensure patent clearance.

Reward for employee invention

In April each year, NOF screens employee inventions and grants rewards to inventors.

This is a group photo taken at the awards ceremony for employee inventions, featuring two rows of people. The six award recipients are seated in the front row holding their certificates, with the Chairman and President seated on either side of them, while four executives stand at equal intervals in the back row.
