“…Our study joins previous studies using patent statistics as measures of technology innovation performance and regards patent statistics as a measure of the results of technology innovation performance (Kapoor et al 2015;Kim and Lee 2015;Picard 2012;Yun et al 2010). Additionally, we analyze the relationship between R&D collaboration and technology performance through business innovation using joint patents.This rest of the paper is structured as follows.…”

Purpose: This study aims to examine the strategic alliance portfolio and the characters of focal firm partners in the eco-friendly car market, and also suggest the important managerial implications and suggestions for firms' managers and policy-makers using the patent information of Toyota and Hyundai as examples. This study identifies the fundamental differences in Hyundai's strategic partnerships through the comparison with Toyota's alliance portfolio. Key literature reviews: This study analyzes the configuration of alliance portfolio using the patent citation information and various patent citation indexes. Many previous studies use patent citation information to analyze the flow of technological knowledge and the relative importance of the technology that companies produce (Hall, Jaffe, & Trajtenberg, 2005). Patents contain a lot of information, which researchers use to derive multiple properties related to technological innovation or technological excellence (Ernst, 2003). Especially, the Current Impact Index (CII), the Technology Strength (TS), the Technology Independence (TI) and the Science Linkage mean the technological innovation of companies (Chang, Chen, & Huang, 2012;Z. Huang et al., 2003;Sung, Wang, Huang, & Chen, 2015).Design/ methodology/ approach: The paper employs patent data for collection of partnership data for both Hyundai and Toyota using joint patent filings, and the alliance portfolios are configured by using co-assignees as partners. In addition, we use patent citation indexes to analyze the relationship between firms' technological alliance and innovation capability.(Expected) findings/results: The results of this study show that; 1) Toyota is actively developing joint R&D activities but, Hyundai is not. Because of this, Toyota has the advantageous position to obtain knowledge and technology than Hyundai due to the high centrality in alliance portfolio. 2) The alliance portfolio of Toyota and Hyundai can be categorized four groups by the degree of collaboration and patent quality. 3) There are differences in the properties of four groups of Toyota's alliance portfolio and Hyundai's alliance portfolio. Research limitations/ implications: This study has several limitations. First, patent information indicates only the cross-section of the company's innovation. Second, joint patents are not the only outcome of joint R&D, and comprise only a very small part of the output from joint R&D activities. In spite of these limitations, the findings suggest how firms can catch up to access the automotive bioplastic market, and offers contributions to theories related to portfolios.

“…However, some limitations in this research are summarized as follows: (1) The US is the biggest market and the USPTO patent database is regarded as the most reliable data source for innovation study [73,76]. However, the results based on only USPTO does not fully reflect a global view.…”

“…However, this study aims to use patent as a proxy for measuring the global landscape of international R&D for the following reasons: (1) patent has been widely accepted in innovation study [69][70][71][72][73]; (2) patent document provides information of inventor and assignee countries which readily facilitate international comparison and internationalization study; and (3) the use of patent to measure internationalization has been confirmed by OECD [74,75]. Accordingly, patent was adapted in this study to understand internationalization of R&D.…”

“…This motivates international patent filing at USPTO and also increase both quality and quantity of information disclosed in USPTO patent document. In addition, USPTO database provides patent citation information which allows diverse patent analysis and therefore is regarded as an reliable data source for investigating global innovation pattern [73,76]. Further, US patent system is a well-established patent system and USPTO is a well-maintained database which encourages researchers to conduct researches in the field of technology, innovation, economics, etc.…”

Global Interdependence of Collaborative R&D-Typology and Association of International Co-Patenting

Economic globalization implies a growing interdependence of resources across countries. Technological R&D and cross-border collaboration are often identified as the primary driving forces in the process. This study aims to holistically analyze global landscape of international collaboration and identify influential countries and the interdependencies among countries. A total of 458,381 international patents granted by the United States Patent and Trademark Office (USPTO) from 1976 to 2013 are analyzed and the structure of international collaboration network is created. It is found that highly developed and small countries usually show a higher degree of internationalization. However, emerging countries such as China present high collaborative influences. The highly skewed collaboration distribution indicates significant inequality of internationalization, which is indeed a hurdle to a country's technological mobility. It can be observed that most pairs of interdependent countries are neighboring or even bordering countries because of their similar historical, linguistic and cultural heritages. Several contributions of this study are summarized as follows: (1) this study first proposes the II, IA, II-IA, IA-AA, and II-IA-AA system for classifying international patent; (2) all international patents (38-year time span) from USPTO are examined without sampling; (3) association rule mining is used to evaluate the interdependency of international collaboration; and (4) network structures illustrating 38 years international co-patenting are visually presented.

“…Text mining of simple patent family titles was used to determine what topics emerged most often as the subject of a patenting process related to data anonymization. Reducing the size of the variability of words utilizes different approaches like filtering, lemmatization or stemming [9]. We used the Statistica Text Mining software to utilize the stemming method.…”

Abstract. The omnipresent, unstoppable increase in digital data has led to a greater understanding of the importance of data privacy. Different approaches are used to implement data privacy. The goal of this paper is to develop a data anonymization patent landscape, by determining the following: (i) the trend in data anonymization patenting, (ii) the type of technical content protected in data anonymization, (iii) the organizations and countries most active in patenting data anonymization know-how; and (iv) the topics emerging most often in patent titles. Patents from the PatSeer database relating to data anonymization from 2001 to 2015 were analyzed. We used the longitudinal approach in combination with text mining techniques to develop a data anonymization patent landscape. The results indicated the following. The number of single patent families is growing with a high increase after 2010, thus indicating a positive trend in the area of patenting data anonymization solutions. The majority of patenting activities relate to the G Physics section. Organizations from the USA and Japan assigned the majority of patents related to data anonymization. The results of text mining indicate that the most often used word in titles of data anonymization patents are "anonym*, "method", "data" and "system". Several additional words that indicated the most frequent topics related to data anonymization were: "equipment", "software", "protection", "identification", or "encryption", and specific topics such as "community", "medical", or "service".
