Abstract
The comparative analysis of the prior art search was made using the training program which National Center for Industrial Property Information and Training performs. The correct answer rate was high when longer years of experience, experiences such as search/retrieval in charge or database. Depending on a technical field, there was the feature according to consideration of search/retrieval or timing of doing prior art search. The improvement in skill of the prior art search according to a technical field and the personnel training for it are important as a premise for protecting valuable invention and performing the practical use. The comparative analysis beyond technical fields is needed.
