As business environment has become more competitive, the R&D strategies of firms have been regarded more important. Patent has information about technology which affects a firm's profit and it is considered as resources which have provided appropriate data for research of innovations and trends in technology. And patent indicators are known as qualitative representation of technology quality in an objective view. Also, they are available for the continuous and systematic analysis. However, most previous studies have focused on developing patent indicators to investigate patent value and characteristics. Furthermore they have limitations that most results is not significant that patent indicators have effect on firm performance-Tobin's q, Intangible assets based on balance sheet, sales and etc. Thus, the purpose of this paper is to propose proper a factor to represent a firm performance and to analyze causal relationship between patent indicators and firm performance. Intangible assets based on market value are employed as one of most significant firm performance indicator. The results indicate that intangible assets are appropriate for analyzing causal relation between patent and a firm performance with 7 significant indicators among 10 patent indicators. Considering firm's exogenous factors, regression analysis of each data for five years is performed. This result is similar to regression analysis of full data for all years.

Now days, firm's technology capability is recognized as important factor to forecast and to evaluate firm's business performance. There are many efforts to develop useful indicators by applying patent information that includes concrete description about technology. Many previous studies analyzed relationship between patent indicators and firm's performance. But they didn't consider time gap between a point of firm's invention activity and a point of firm's performance improvement. They didn't considered a character of industrial fields either. To overcome these limitations, we selected IT industry for target analysis industry. Time-series patent data and financial data from 41 American IT firms between 2000 and 2011 were used to analyze. In this study, We empirically analyzed subsequent effect of patent indicators on firm's business performance by using correlation analysis and regression analysis.

Patents are system to promote the development of industry by disclosing technology. The importance of recent patent is being emphasized. For this reason, companies apply for many patents. And they analyze the patent. Patent analysis helps to protect and foster their technology. Previously this method has been carried out by experts. Expert-based patent analysis, however, has the disadvantage of being time-consuming and expensive. Consequently, we try to solve this problems by developing prediction model. Therefore, this paper proposes a data-based patent analysis method using quantitative indicator and textual information. We confirmed the practical applicability of the proposed method through 1,831 autonomous vehicle patents. As a result, it was possible to confirmed that safety and lane detection related technologies are important.

With the advent of a recent knowledge-based society, interest in patents is steadily increasing. The patent is an important indicator that can capture the level of R&D investment and technology development. In an era of deepening new protectionism and the pandemic of COVID-19, patents play an important role in sustainable economic development and establishing a strong domestic industrial ecosystem. In this paper, we analyze the impact of patent applications on the corporate performance of the Korean manufacturing industry over the past 21 years from 1999 to 2019. We divide patents into overseas patents and domestic patents and analyze the respective effects on the entire manufacturing industry, ICT industries, and non-ICT industries. Major findings are summarized as follows. First, patents have a positive effect on both exports and sales of Korean manufacturing companies. Second, overseas patents have a greater impact on corporate performance than domestic patents. Third, Patents have a more positive effect on ICT industries than on non-ICT industries.

Along with the rapid development of industrial technology, the industrial structure has been continuously changed. Accordingly, safety technologies have been gradually developed to be applied into various industrial fields as well, not limited to a specific industry area. As a result, it became important to analyze and predict trends of safety technology development in order to establish technology strategies for industrial safety. In particular, since patents are easily accessible to gather the technology and business information, many studies have highlighted technology forecasting using patent information. Thus, this study proposes the patent analysis of monitoring trends of safety technologies of industry fields, taking into account both static and dynamic aspects through index and text analysis. First, patent documents containing safety-related keywords are collected from the WIPSON database for extracting technology information. Then, the development trends of safety technologies by industry fields are identified and analyzed through the analysis of indicators such as marketability, growth, and activation. The results of various indicator analyses of safety technologies are visualized to compare among industrial safety technologies for businesses and technology developers. Second, textmining algorithm is applied to identify trends of specific technology keywords of major industries extracted from patent index analysis. As a result, it is expected that the safety manager uses the patent analysis of safety technologies to provide safety technology information with safety-related companies and institutes. The extracted safety technologies are applicable to business practice and predict future promising technologies.

There have been studies to evaluate valuation of firms by using patents in various ways. Also, the theory that value of patents helps enterprise's growth is valid in economics. However, when evaluating the value of the company, through the patent evaluation has not been used. Because of previous studies researched relation between patents and firms only at certain points. To solve this problem, this study intends to analyze lag between patent and profitability of the firms. In this study, we classified top 100 software firms in the United States through PBR, PER and value of intangible assets by using cluster analysis. And we applied Almon's distributed lag model to each cluster to find out lag between patent and profitability of the firms. As a result, in the cluster of more valuable companies, patents have an effect on profitability of the firms at regular lags. This study indicates that the patents are an important indicator to assess companies.

과학이 기술발전을 이끄는 주요 추진력이며 기술혁신이 궁극적으로 경제발전에 기여한다는 것이 밝혀짐에 따라 선진국은 과학과 기술간 상호작용을 중요하게 다루고 있다. 그러나 한국의 기술발전을 이끈 과학적 기반에 관한 연구가 거의 이루어지지 않았으며 한국의 기술과 강력한 연계를 맺고 있는 학문분야에 대한 연구도 미약한 실정이다. 따라서 이 연구는 특허에 인용된 과학논문을 이용하여 과학기술자의 인용행태를 추적하고, 인용행태 이면에 놓인 과학과 기술간 상호작용을 측정하고자 하였다. 과학논문이 특허의 혁신가치에 어떠한 영향을 미치고 있는지를 살펴봄으로써 기술개발에 있어 과학논문의 중요도를 밝히고자 하였다.

본 연구에서는 급진적 혁신을 수행하는 기업의 특징을 특허 데이터를 중심으로 살펴보았다. 1980년도부터 특허 정보는 기업의 성과를 측정하기 위한 중요한 지표로 활용되어 왔지만, 급진적 혁신을 대표하기는 어려웠다. 따라서 본 연구를 통하여 특허 집약 산업(Patent Active Industry)인 제약 산업에서 특허 정보가 급진적 혁신 지표로서 활용 될 수 있는지 알아보고자 하였다. 분석을 위해 약 10년간의 FDA 승인 데이터, 국외 기업의 특허 데이터를 활용하였으며 네트워크 중심성 분석(Centrality Analysis)과 비모수적 분석법인 윌콕슨 부호 순위 검정(Wilcoxon Signed Rank Test)을 실시하였다. 네트워크 분석 결과 급진적 혁신을 수행하는 기업의 경우 다른 기업들보다 대학 및 타 제약 기업과 협력 활동이 활발함을 시각적으로 확인 할 수 있었으며, 통계분석 결과 급진적 혁신을 수행하는 기업과 그렇지 않은 기업 간 연결 중심성(Degree Centrality)과 근접 중심성(Closeness Centrality)에 차이가 있음을 확인 할 수 있었다. 본 연구의 결과는 기업의 연구개발 전략 및 정책 수립에 활용 될 것을 기대하며, 향후에는 기업의 급진적 혁신에 영향을 미치는 요소가 무엇인지 정량 분석이 가능할 것이다.
