Strategic Intellectual Property Formation Activities and Strengthening the Governance System

While utilizing intellectual property information analysis, we promotes "strategic dialogue" between business divisions and intellectual property divisions with the aim of forming strategic intellectual property.
In addition, we have strengthened its governance system through regular reports to the Strategic Management Committee and the Board of Directors and deliberations in the Meeting of Executive Officers and the Board of Directors.

Strategic Intellectual Property Formation Activities and Strengthening the Governance System

Strategic Dialogue (Strategic Utilization of Intellectual Property Information)

From the development policy review stage, We, Intellectual Property Dept., make strategic analysis of intellectual property. We have conversations (strategic dialogue) with business divisions (including top management) to add intellectual property perspectives to management and business policies.

Strategic Dialogue (Strategic Use of Intellectual Property Information)

As an effect of the strategic dialogue, we aim to reduce various risks that occur during the commercialization stage and at the same time to form intellectual property rights that contribute to our business.

Promotion of Branding

Mitsubishi Materials has branded new materials and is actively building them.


GloBrass and ECO BRASS are lead-free brass with excellent machinability alloys that are controlled to a lead content of 0.09% or less and complies with the EU's ELV Directive, RoHS Directive, and various regulations such as drinking water.


MOFC is a lineup of high-quality, high-performance oxygen-free copper products incorporating our core technologies-oxygen-free copper production technology and material-design technology.
In 2021, an oxygen-free copper MOFC-HR that meets high strength and heat resistance was newly added.


CLEANBRIGHT is an alloy that maintains the sterility and antiviral properties of copper but does not cause discoloration. It combines high strength and processability as a material, and can be processed into a variety of parts that require antimicrobial properties.

Invention Reward System

Mitsubishi Materials has established Employee Invention Regulations in which an invention reward system is implemented.
In addition to providing a fixed amount of reward at the time of filing and registration of patents, utility models, and designs, performance rewards are provided when there is a certain profit to which the patents, utility models, and designs contributed.
Through the revision of the regulations, we have attempted to promote inventions, such as eliminating the upper limit on the amount of incentive money and applying it to confidential inventions.
We will continue to improve our incentives for inventors so that they can be fairly evaluated.

Intellectual Property Education

We provide training for Group employees to improve their intellectual property literacy, utilize intellectual property information in business activities, and form effective intellectual property. In addition to Trainings by job grade for the purpose of acquiring knowledge about general intellectual property, practical trainings aiming for specialized and strategic utilization of intellectual property is provided as selective education.
