“…For this reason, the process of matching a company-owned patent with a company owner is not always accurate. Accordingly, Hall et al (2001), He et al (2018), Julius and De Rassenfosse (2014), and Thoma et al (2007) have aimed to standardize the names of applicants, with Kim et al (2016), Lee et al (2019), and Kang et al 2019focusing on Korean firms. This study uses the OECD Harmonised Applicants' Names (HAN) database, which is based on text-matching algorithms such as the one presented by Kang et al (2019).…”

The principle of relatedness, which helps estimate the affinity between economic activities, suggests that cities, regions, and countries are more likely to undertake new economic activities when they already perform related activities. This empirical principle has been confirmed for various dimensions---cities, regions, and countries---and their activities--- developing new technologies, products, and industries. However, the technological diversification of firms is yet unexplored. Is a firm more successful at entering a new technology when it has already accumulated related technologies? Here, we explore this issue using a unique dataset that contains firms' patent data and financial and market information. In particular, we examine Korean firms listed in the Korean stock market that published patents at the patent offices in Korea, Europe, and the United States from 1984 to 2004. We develop a technological relatedness measure to estimate whether a firm has already published patents with similar technologies. We find that firms are more likely to develop a new technology when they already have related technologies. Interestingly, technological relatedness shows an increasing return to related knowledge. We also check the robustness of this effect using propensity score matching and find that the effects of technological relatedness and its increasing return behavior remain significant when controlling for potential confounding effects. These findings extend the concept of relatedness to a firm's technological diversification and show that the development of a firm's technological knowledge is shaped by its technological relatedness.

“…In all cases, the Latin names of the attorney firms were harmonized using a bigram match as per the procedure used in Julius and de Rassenfosse [2014]. A business executive, fluent in Japanese and Chinese, Ms Helen Szaday, reviewed the method of firm name identification.…”

Is the Patent System an Even Playing Field? The Effect of Patent Attorney Firms

The patent system underpins the business model of some of the fastest‐growing companies. Used appropriately, it should support frontier technologies and nurture new firms. Used perniciously, it can stifle innovation and protect established technological behemoths. We analyze patent examination decisions at the American, European, Japanese, Korean, and Chinese patent offices and find evidence that patent attorneys have a surprisingly significant role in the patent system. Our results suggest that some forces within the examination system maintain the uneven playing field by allocating monopoly rights to inventors with better access to influential attorneys, rather than leveling it by favoring inventors with better, nonobvious ideas. Attorney quality is most important, vis‐à‐vis invention quality, in less codified and more rapidly changing technology areas such as software and ICT.

“…For example, while the International Business Machines Corporation is the same as IBM, they may be regarded as different applicant names in the patent data. To address this issue, scholars have developed methods for standardizing applicant names [49]- [51]. Kang et al [52] used the OECD Harmonised Applicants Names (HAN) database, which includes unique applicant identifiers, to disambiguate applicants' names.…”

Technological Leadership in Industry 4.0: A Comparison Between Manufacturing and ICT Sectors Among Korean Firms

et al. 2023

View full text Add to dashboard Cite

This paper examines the technological structures of the manufacturing and the ICT sectors in Korea to examine the potential shift of dominant technological sectors in the era of the Fourth Industrial Revolution (4IR). By using patent data of Korean firms from 1990 to 2021, we find that the manufacturing sector has been the dominant technological leader in Korea in terms of both the number of patents and the diversity of technologies, even in the era of 4IR. Although the ICT sector has shown an increasing focus on Industry 4.0 (I4) technologies after the 2000s, indicating the potential for a shift in dominance in the future, the gap between the two sectors is still significant. The study also reveals that the manufacturing sector tends to diversify technologies, while the ICT sector specializes in several target technologies. Our analysis also suggests that both sectors exhibit path-dependency, with the ICT sector exhibiting stronger characteristics, and firms in both sectors exhibit the tendency of intensive and extensive margin in their patenting activities, but this tendency is stronger for firms in the manufacturing sector.
