Invention Reward System
Mitsubishi Materials has established Employee Invention Rules and operates an invention incentive system within these rules.
With regard to patents, utility models, and industrial designs, we have recently revised the timing of payment of incentives to inventors in order to increase incentives for inventors to create inventions.
