Abstract: An evaluation-data acquisition unit acquires evaluation data on a target intellectual property right which is an intellectual property right to be evaluated. A necessity determination unit determines the necessity of the target intellectual property right on which the evaluation data is acquired by the evaluation-data acquisition unit by using an evaluation model that is generated by machine learning using evaluation data on intellectual property rights and determination results on the necessity of the intellectual property rights as training data and that receives input of evaluation data and outputs necessity determination data indicating the necessity.

Abstract: Provided are a laser machining device and a laser machining method capable of stably operating an autofocus function without causing an unfavorable state such as an overshoot etc. A laser machining device and a laser machining method of the present invention performs a normal AF (autofocus) control when a scan position of the machining laser light and the detecting laser light is located in a work central portion, and performs a slow-tracking AF (autofocus) control with a trackability to a displacement of a main surface of a work reduced to be lower than a trackability of the normal AF control when the scan position of the machining laser light and the detecting laser light is located in a work end portion.
