Core technologies and key industries in Taiwan from 1978 to 2002: A perspective from patent analysis

Summary This paper uses United States patent classification analysis to study the development of core technologies and key industries in Taiwan over the last 25 years, from 1978 to 2002. After counting the number of Taiwan-held United States granted utility patents, the authors divide the years into three phases: from 1978 to 1994, with less than 500 patents each year; from 1995 to 1999, with 500-2,500 patents each year; from 2000 to 2002, with annual patents greater than 2,500. The results show that for both Taiwans core technologies and key industries, there was a great diversity at the first phase, while a mainstream forms and matures at the second and the third phases. However, industrial development at the third phase was more concentrated and focused than previous ones. Overall, Taiwan has clearly moved from a manufacturing-based economy to an innovation-based one, with its focus on high-tech industries during the previous 25 years.     

Prediction of emerging technologies based on analysis of the US patent citation network

The network of patents connected by citations is an evolving graph, which provides a representation of the innovation process. A patent citing another implies that the cited patent reflects a piece of previously existing knowledge that the citing patent builds upon. A methodology presented here (1) identifies actual clusters of patents: i.e., technological branches, and (2) gives predictions about the temporal changes of the structure of the clusters. A predictor, called the citation vector, is defined for characterizing technological development to show how a patent cited by other patents belongs to various industrial fields. The clustering technique adopted is able to detect the new emerging recombinations, and predicts emerging new technology clusters. The predictive ability of our new method is illustrated on the example of USPTO subcategory 11, Agriculture, Food, Textiles. A cluster of patents is determined based on citation data up to 1991, which shows significant overlap of the class 442 formed at the beginning of 1997. These new tools of predictive analytics could support policy decision making processes in science and technology, and help formulate recommendations for action.

Identifying key technologies in Saskatchewan, Canada: Evidence from patent information

This study attempts to identify the areas of technological strength of the province of Saskatchewan, Canada, whose economy is heavily based on natural resources, by analyzing patent information. 606 US patents held by Saskatchewan organizations were identified. The results show that inventive activities are steadily growing and Saskatchewan’s technological development has experienced three stages. The Initial stage (1971–1985) was dominated by traditional resource-based technologies; the Emerging stage (1986–1995) was characterized by the emergence of new technologies in the Drugs & Medical field; and the Developing stage (1996–2009) was marked by more of a balance between traditional and new technologies. In Canada and worldwide, inventive activities in Computers & Communication field have been most prominent since the last decade. However, Saskatchewan demonstrates a different path from the rest of the world. While traditional technological fields still dominate in the province, it is gradually building its strength in the Drugs & Medical field. The results present a possibility to diversify the provincial economy if policy makers develop strategies to facilitate the transfer of new technologies to industries.

Mapping countries cooperation networks in photovoltaic technology development based on patent analysis

Research activities on solar energy has been growing and use of patents becomes an important innovation source for many types of studies. This paper aims to analyze solar photovoltaic (PV) patents and describes its assignees cooperation profile. PV patents based on IPC Green Inventory code were selected from 1990 to 2014, filtered out co-ownership patents and use social network analysis (SNA) to find PV technology development networks. Main findings are an increase of patents assignees over the years and a general concern for develop technologies “Devices adapted for the conversion radiation energy into electrical energy”, “Assemblies of a plurality of solar cells” and “Silicon; single-crystal growth”. SNA enabled to identify four countries clusters that presented cooperation behavior and shared similar concerns in PV technology development. The USA, China, Spain and Korea were main countries of each cluster. Furthermore, through network statistics, it implied that a country that had more patents was not the most important on that technology development. The USA, Germany and UK were the most relevant countries in PV technologies because they were the ones with more cooperation with other countries and with the most collaborative countries overall. Thus, these countries are the largest holders and influencers in PV technologies development. Based on the structure and interaction between country clusters, it is possible to understand who cooperates or competes with whom. So, this information allows establishing strategies of partnerships, or even of competition, between countries, firms and research centers.

Technological collaboration patterns in solar cell industry based on patent inventors and assignees analysis

This study examines technological collaboration in the solar cell industry using the information of patent assignees and inventors as defined by the United States Patent and Trademark Office. Three different collaborative types, namely local (same city), domestic (different cities of the same country), and international collaboration, are discussed. The general status of solar cell patent collaborations, transforming trends of collaborative patterns, average numbers of assignees and inventors for three collaborative types, and international collaboration countries are studied. It is found that co-invented patents and co-assigned patents have both increased in numbers during the four decades studied, and that collaboration between technology owners is very low while the collaboration between inventors is active. Domestic collaboration is the main collaborative pattern for both assignee collaboration and inventor collaboration. The other two collaborative types show contrary trends: international collaboration has slowly risen in the past decades while local collaboration has dwindled. The US has the largest number of internationally collaborative patents worldwide, though such patents account for a low portion of total US patents. In contrast, China has a small total number of patents and internationally collaborative patents, however its international collaborative shares are higher. The international collaboration patents among countries are few. A co-assigned patent analysis indicates that the main international cooperation partner of the United States is Japan. Based on an international co-invented patent analysis, the main international collaboration partners of the United States are Britain, Japan, and Germany; and the United States is also the most important collaboration partner of China.

Exploring pathways of regional technological development in China through patent analysis

Recently, China has experienced a surge in patenting and become the leading applicant nation worldwide. The technological substance of this growth, however, has become increasingly doubted as China's governments continue to promote patenting as a target per se. Against this background, the paper explores the structure of Chinese patenting from a regional perspective. Firstly, it analyses the technological profile, public component and outward orientation of specific provinces' technological ecosystems. Secondly, it connects these specific profiles to regions' recent growth in patent applications. Concluding, it finds that there are indications of both politically induced and technologically substantial growth in applications.
