“…Research in this category focuses on which patents are important in a patent network. Chang, Lai, and Chang [32] utilized a patent citation network analysis for finding basic patents and relationship between cited patents. This study tried to analyze groups of technology diffusion from basic patents by using the hierarchical cluster analysis.…”

Abstract:The aim of this paper is to propose a method to investigate a firm's strategic changes. Technologies or technological capabilities are a major resource for achieving competitive advantages, so a firm's R&D effort to improve capabilities on specific technologies is aligned with strategic direction. Therefore, this research analyzes changes in R&D efforts by identifying key R&D personnel using patent co-inventor network and social network analysis. Based on characteristics of application and granted patents, the method analyzes current and future R&D efforts and so identifies strategic changes of a firm. We conducted an empirical analysis using the patents of Samsung Electronics. Our method analyzed the current and future strategies of Samsung Electronics and the result shows clear strategic changes in their focal technologies and business.

“…Patent citation networks model was studied by graph theory based on nodes (patents) and their linkages [24]. This was researched and used in diverse fields of technology analysis for improving the technological competition of a company [21,22,24,25]. To construct a network model for technology analysis, patent citation networks uses the citation results between patents.…”

A Network Analysis Model for Selecting Sustainable Technology

Most companies develop technologies to improve their competitiveness in the marketplace. Typically, they then patent these technologies around the world in order to protect their intellectual property. Other companies may use patented technologies to develop new products, but must pay royalties to the patent holders or owners. Should they fail to do so, this can result in legal disputes in the form of patent infringement actions between companies. To avoid such situations, companies attempt to research and develop necessary technologies before their competitors do so. An important part of this process is analyzing existing patent documents in order to identify emerging technologies. In such analyses, extracting sustainable technology from patent data is important, because sustainable technology drives technological competition among companies and, thus, the development of new technologies. In addition, selecting sustainable technologies makes it possible to plan their R&D (research and development) efficiently. In this study, we propose a network model that can be used to select the sustainable technology from patent documents, based on the centrality and degree of a social network analysis. To verify the performance of the proposed model, we carry out a case study using actual patent data from patent databases.

“…Patents that are often cited have more linkages, suggesting the representativeness of the technology and the significance to guide innovation toward future technologies (Albert et al 1991;Carpenter et al 1981;Ernst 1995). Patents that are cited less have lower linkages, suggesting that the technology has no representativeness and little influence on future technologies (Albert et al 1991;Chang et al 2009). The core technology is situated in the center of a network that plays a crucial role, thus promoting technology diffusion.…”

Abstract. In recent years, the issues of energy use reduction and sustainable development have garnered considerable interest. This study has conducted a patent search using United States Patent and Trademarks Office (USPTO) data to investigate technological trends in sustainable development, using shading devices for buildings as an example, because they have the potential to save energy by effectively preventing heat from coming indoors, and lowering the indoor heat load. The purpose of this study was to explore the status of shading devices and analyze patent activity, major assignees, assignee countries, core technology fields, patent citations, potential competitors of patent assignees, and developmental path based on patent analysis using a database that spanned the years from 1974 to 2011. The results provide a clear picture of, and evidence for, the pattern of shading device technology; they suggest that automatic sensing shading devices are the focus of current technological developments, thus saving time and costs in future research development.
