Abstract
We have built efficient other companies' patents evaluation system which Intellectual property group and engineers do work together. By this system, it was easy for either party to see the progress of the other party and management status is easily visible using the patent investigation tool. I would like to report a summary of the system and matters that require attention relating to the operation of the system. In addition, I would like to report data utilization example, which is building of a patent map using the original keywords that is one of the important items of the system.
