“…Previous studies have asserted that the number of IPCs that a company is involved with can be used as an indicator to assess the company's innovation performance (Hu and Rousseau, 2015). Studies have also claimed that an increase in IPCs that the patents of a company have corresponds to increases in both the diversification of technologies possessed by the company and the probability that the company enters a new technical area (Chen, Jang and Wen, 2010). The present study focussed on the number and values of IPCs for a single patent.…”

Patents play a crucial role in determining the economy, industrial development, and R&D of a country. Extant patent literature has focussed on the decision model of the econometric method, which enables researchers to understand the short-term explanatory power of various factors for patent value. However, this method cannot be used to observe the degradation rate and growth trajectory of the patent value. In this study, we proposed a dynamic time-series design to further explore the growth trajectory of patent value by using the latent growth curve model. The results show that backward citation, non-patent reference, and number of claims positively affect the patent value growth rate. Patent disclosure information and characteristics are crucial for exploring the value of patents. Patent value is typically established on the basis of knowledge stock, patent breadth and international linkage. Therefore, this study applied an experimental map to validate the linkage relationship of the studied dimensions to provide governments, industries and patent assignees with some practical suggestions.

“…The most common of these is the lawsuit for patent infringement. At the beginning of production, if a manufacturer fails to carry out a detailed patent analysis of the relevant technology, it will face a painful price in the face of foreign manufacturers' recovery of royalties [27]. For the industry, the more detailed the patent information, the easier and more accurate it is for manufacturers to draw up the company's business strategy, R&D strategy, and patent strategy.…”

Recently, the application of blockchain to the setting, management, and trading of the energy system has formed an innovative technology and has attracted a lot of attention from industry, academia, and research. In this study, we use patent analysis technology to explore the development trends of the energy system with blockchain technology. During the patent analysis process, this study makes corresponding analysis charts, such as patent application numbers over time, patent application numbers for main leading countries, applicants, patent citations, international patent classification (IPC), and life cycle. Relative research and design (R&D) capability of the top ten applicants is estimated and the cluster map of the technology is obtained. The technical features of the top five IPC patent applications are related to the cluster map to show the development of energy blockchain technology. Through this paper, first, the basics of the blockchain and patent analysis are illustrated and, moreover, the reason why and how blockchain technology can be combined with the energy system is also briefly described and analyzed. The results of the patent analysis of energy blockchain technology indicate that the United States leads the way, accounting for more than half of the global total. It is also interesting to note that the participants are not from traditional specific fields, but included electric power manufacturers, computer software companies, e-commerce companies, and even many new companies devoted to blockchain technology. Walmart Apollo, LLC and International Business Machines Corporation (IBM) have the highest number of patent applications. However, Walmart Apollo, LLC ranks first with a greater number of inventors of 36, an activity year of 2 years, and a relative R&D capability of 100%. IBM ranks second with an activity year of 3 years and a research and development capability of 91%. Among various applicants, IBM and LO3 energy started earlier in this field, and their patent output is also more prominent. The IPC is mainly concentrated in G06Q 50/06, which belongs to the technical field of the setting and management of the energy system including electricity, gas, or water supply. Currently, most projects are in the early development stages, and research on key areas is still ongoing to improve the required scalability, decentralization, and security. Thus, energy blockchain technology is still in the growth period, and there is still considerable room for development of the patent in the later period. Moreover, it is suggested that the novel communication module such as the combination of the consortium blockchain and the private blockchain cold also provide their own advantages to achieve the purpose of improving system performance and efficiency.

“…Next, based on the improved vocabulary query methods, a patent retrieval strategy was formulated by selecting keywords in every subfield. As shown in Figure 2, the determination of the ICM technology classification system and patent retrieval strategy refer to three kinds of documents: (1) research literature related to the ICM, whose research contents can be divided into patent bibliometrics [12,[39][40][41], developing situations [11][12][13]15], technology fields [14,18], etc. ; (2) industrial information related to the ICM, which includes industrial research reports [49,50], popular science books [51], etc.…”

“…For example, in an earlier study, patents issued to ICM enterprises from 1975 to 1994 were utilized to examine the effects of the value of a firm's technological advancement and of the newness of its technology on the probability of its failure [12]. In 2010, another study showed a bibliometric analysis of the patent publications of 73 Taiwanese IC design firms covering the period from 1995 to 2007 [39]. Using the patents from Taiwan and U.S. IC design and manufacturing firms, Tsai [40] shed light on the patent and Research and Development (R&D) spillover effects on productivity.…”

Abstract:With the intensification of international competition, there are many international technological collaborations in the integrated circuit manufacturing (ICM) industry. The importance of improving the level of international technological collaboration is becoming more and more prominent. Therefore, it is vital for a country, a region, or an institution to understand the international technological collaboration characteristics of the ICM industry and, thus, to know how to enhance its own international technological collaboration. This paper depicts the international technological collaboration characteristics of the ICM industry based on patent analysis. Four aspects, which include collaboration patterns, collaboration networks, collaboration institutions, and collaboration impacts, are analyzed by utilizing patent association analysis and social network analysis. The findings include the following: first, in regard to international technological collaboration, the USA has the highest level, while Germany has great potential for future development; second, Asia and Europe have already formed clusters, respectively, in the cooperative network; last, but not least, research institutions, colleges, and universities should also actively participate in international collaboration. In general, this study provides an objective reference for policy making, competitiveness, and sustainability in the ICM industry. The framework presented in this paper could be applied to examine other industrial international technological collaborations.
