제품혁신수준 분석을 위한 특허정보 기반 지표 개발

Abstract

Analyzing the innovation level of a product is important in that it enables identification of the product"s promise and analysis of product development stage. Although there are existing studies to measure the innovation of the technology using various patent indicators, attempts to quantify the innovation level from the product point of view have been insufficient and have mainly relied on the qualitative evaluation of experts. In this study, we use product name and product-patent relation databases to define the product innovation as a combination of quantitative and qualitative progress of the analyzed product, analyze the innovation pattern of the product, and develop an index for product innovativeness analysis. As a result of analyzing 100 sample products, it was found that spiral development patterns appeared over time in the products with a certain number of related patents. This study can be used to determine the direction of future development of the products of interest by measuring their innovativeness with the proposed index.
