The strategic measure is required to operate industrial property rights and patents become more and more important in the world. Engineers and scientists need to assume excercise of right for patent application from R&D stage while special technological knowledge is required to excercise the right.

We devote ourselves to meet these demands and have tried to make specifications aiming for technical proposal and endeavors of aquisition of right.
