先前有大量关于创新与专利之间关系的研究。这些研究表明，专利中含有大量噪音，除非对单个专利的价值进行修正，否则简单地统计专利数量并不能构成一个非常有用的指标。从以寻找这样的指标来表示单个专利的价值的目的（即，确定有价值的专利的特征的研究）为目的进行的研究中，已经提出了多种价值指标。然而，迄今为止的研究主要集中于拥有专利所带来的商业或私人价值，而很少关注技术知识或社会价值方面的价值。 RIETI在2007年对发明人进行的一项调查中，在向发明人询问单个专利的价值时使用了描述宽泛概念的术语，这为分析专利价值背后的多种因素及其相互影响提供了绝佳的机会。本研究的目的是利用RIETI的发明人调查数据和结构方程模型方法，阐明专利的技术价值和商业价值之间的关系以及影响它们的潜在因素。研究结果表明，发明人的科技动机会对商业和技术价值产生积极影响，同时，金钱或促销动机不会对专利价值产生任何直接影响。该模型还表明，学术联系将对技术价值产生强烈的积极影响，但对商业价值产生微弱的负面影响。此外，这些关系根据技术领域的不同而存在更显着的差异。
There is a considerable volume of prior research on the relationship between innovation and patents. Those research studies reveal that patents contain a great deal of noise, and unless a correction is made in terms of the value of individual patents, a simple count of the number of patents does not constitute a very useful indicator. From research that has been conducted for the purpose of finding such an indicator to show the value of individual patents (that is, research to identify the characteristics of valuable patents), many kinds of value indicators have been proposed. Nevertheless, research hitherto has focused primarily on business or private value derived from the possession of patents, and little attention has been paid to value in terms of technical knowledge or social value. In a survey of inventors conducted by RIETI in 2007, terminology describing broad concepts was used when questioning inventors about the value of individual patents, and this has provided an excellent opportunity to analyze the multiple factors lying behind the value of patents and how they impact one another. The purpose of this research is to use data from the RIETI survey of inventors and structural equation modeling methods to elucidate the relationships between the technological and business value of patents, and the latent factors that influence them. The findings show that a scientific-technological motive for inventors would have a positive effect on both the business and technological value, meanwhile, the monetary or promotion motive would not have any direct effects on the value of a patent. The model also suggests that academic linkage would have a strong positive effect on the technological value but a weak negative effect on the business value. Furthermore, these relationships differ more markedly according to technological field.
