R&D Initiatives Related to Intellectual Property

Basic thinking about intellectual property

The Daicel Group respects intellectual property rights held by third parties, recognizes that the intellectual property rights held by the Company (patent rights, utility model rights, trademark rights, design rights, etc.) are important assets, and strives to maintain and protect those rights.

Code of Conduct of Daicel Corporation(8-3 Maintenance and protection of intellectual property (IP) rights)

Investing in Intellectual Property and Intangible Assets

With the basic philosophy of remaining a company that makes lives better by co-creating value, the Daicel Group invests in intellectual property and other intangible assets in order to continue providing value. At the same time, we remain committed to meeting the needs of society while sharing a philosophy that transcends the limitations of companies and industries.

Investing in Intellectual Property and Intangible Assets

Internal system related to intellectual property

In the Intellectual Property Center, under the slogan of "Proactive IP," we are engaged in intellectual property activities led by an intellectual property activity team consisting of (1) Business and Planning Divisions, (2) the Research & Development Division, and (3) the Intellectual Property Center. By "creating" and "exploiting" intellectual properties, we support our monozukuri manufacturing, and by "combining" intellectual properties, we promote innovations that lead to new business creation, enhance Daicel's brand power, and bolster business of the Daicel Group. As clarified in Daicel's "Accelerate 2025" Mid-term Management Strategy, along with "Research" and "Development," we will strengthen intellectual property activities as one of the means to accelerate "Innovation and Business Development."

Intellectual Property Center's Vision

Intellectual Property Activity Team

Approximately 35 intellectual property activity teams in Daicel and its group companies are involved in the certification of inventions, decision-making on whether to file a patent application for an invention or keep it as confidential know-how, patenting, judgments on the necessity of patent maintenance, patent exploitation, examination and avoidance of possible infringement of other companies' patents, and response to patent litigation.

Mid-Term Management Strategy

Promoting the IP Landscape, "a Compass for Management, Business and Research"

In 2019, Daicel's Intellectual Property Center established a dedicated team to promote IP Landscape (IPL), and in 2022 this IPL team was reorganized to incorporate all our IP staff and positioned our IPL as a fundamental part of all Daicel's intellectual property activities. By IPL, we mean "to tap into all available information, not only intellectual property but also technologies, papers, markets, companies, politics, laws, etc. so that we can visualize the situation in which Daicel's management, business, and research are placed, and plot a path to ensure these activities are successful." Based on this idea, we view an IPL as "a compass for management, business, and research" and promoting our activities.
In addition, since these activities cannot be achieved by the Intellectual Property Center alone, we are proceeding in close cooperation with relevant divisions on individual specific R&D themes and business planning themes. Now that the awareness of our IPL is growing within our company, this IPL is beginning to play a role in the decision-making of each business unit. We are making efforts every day so that our IPL can help open doors to the future of Daicel.

Human Resources Development

We are working to improve the intellectual property literacy of our engineers through a human resources development program implemented in collaboration between the Intellectual Property Center and Personnel Group.

  1. 1Implementation of rank-specific training (new employees, mid-career employees, new managers)
  2. 2Provision of e-learning (protection of patents, trademarks, copyrights, trade secrets and know-how; patent search and analysis, etc.)
  3. 3Introduction of “Intellectual Property Management Technician Grade 3” qualification as one of the requirements for promotion to managerial positions in engineering departments

Activity Results

Utilization of Intellectual Property in Standardization

A quantification method of sparkle phenomenon on displays*, which was jointly developed with Komatsu NTC Ltd., was adopted as Japan Industrial Standards (JIS) under the title of "Determination of magnitude of display sparkle" (JIS C 1006) on December 20, 2019.
The method and equipment to numerically calculate sparkle have been patented as “Equipment and Method of Determining Sparkle” (JP Patent No. 6294904), and Daicel and Komatsu have announced they will license this patent on reasonable and non-discriminatory (“RAND”) terms.

  • *A phenomenon in which the uneven structure of anti-glare display surface diffuses the light emitted from the display, causing sparkle of the screen.
