미래의 기업 환경은 유형 자산으로서의 물질적인 자산보다는 지적재산권 등의 무형 자산에 대한 중요성이 더욱 강조될 것이다. 지적재산권 중 특허의 가치를 통하여 기업의 성과가 변화함을 보인 많은 선진국의 사례 연구-Machluo(1958)으로부터 시작하여 Mansfield(1965), Beck. R(1976), Parker. J(1978), Rosegger. G(1980), Scherer. F(1980) 등 1990년 이후는 무수히 많음-는 미래 기업 경쟁력이 질적 가치가 우수한 특허를 얼마나 보유하고 이를 얼마나 효율적으로 관리하는가에 달려있음을 보여주고 있다. 본 연구는 국내 화학기업의 특허관리 유형을 5가지 특허 지표들-국내특허출원건수(relative patent applications), 국내특허등록건수(patent granted), 유효특허건수 (valid patents), 집중도(concentration of patents in subclass), 국제특허출원건수(overall international patent applications)-을 통하여 구분하였으며, 이들 변수를 가지고 군집화 하였을 때 각각에 해당하는 클러스터에서 기업성과에 차이가 나타나는지 알아보았다. 본 연구에서 특허를 기업성과와 관련시켜 설명한 점은 기술혁신 능력 내지는 기술경쟁력을 측정하는 척도로서 특허를 바라본 것이며, 특허의 전략적 관리와 활용이 독점적 시장 우위의 확립과 경제적 성과 향상, 통합적인 경쟁력 강화 측면에서 기업의 성공을 가져올 것으로 보기 때문이다.

Zinc Sulfide (ZnS) is one of the II-VI semiconducting materials, having novel fundamental properties and diverse areas of application such as light-emitting diodes (LEDs), electroluminescence, flat panel displays, infrared windows, catalyst, chemical sensors, biosensors, lasers and biodevices, etc. However, despite the remarkable versatility and prospective potential of ZnS, research and development (R&D) into its applications has not been performed in much detail relative to research into other inorganic semiconductors. In this study, based on global patent information, we analyzed recent technical trends and the current status of R&D into ZnS applications. Furthermore, we provided new technical insight into ZnS applicable fields using in-depth analysis. Especially, this report suggests that ZnS, due to its infrared-transmitting optical property, is a promising material in astronomy and military fields for lenses of infrared systems. The patent information analysis in this report will be utilized in the process of identifying the current positioning of technology and the direction of future R&D.

Objective: The purposes of this study are to survey general and ergonomics relevant patents of major foreign countries, to classify the ergonomics patents into some categories frequently found in the patents lists surfed and to compare the results with those of Korea. Background: Under today's severe competitions between countries and between companies, the intellectual property has never been more important. It is needed to investigate Korea's positions and worldwide status of patent applications and grants for general and ergonomics patents. Method: This study was mainly based on relevant websites surfing such as KIPRIS, FPO, EPO, WIPO, etc. Results: The results showed that while Korea placed fourth in patent applications and grants in 2012, following US, Japan and China, Korea ranked seventh in the number of ergonomics patents. Of the overseas ergonomics patents, the proportion of tool/device was the second highest to category of others, followed by chair/desk, grip/handle and keyboard, etc. Compared to the overseas ergonomics patents, Korea showed a slightly different trend that there were less patents for specific fields of ergonomics such as grip/handle, keyboard, tool/device, etc. Conclusion: The number of ergonomics patents of Korea was behind most foreign countries surveyed in the number of patent applications and grants of, and there were many categories of overseas ergonomics patents. Application: This study would be used as a reference or guideline when developing varying ergonomic products or applying to ergonomics patents.

As basic research to develop HEV and EV agricultural field machinery, the present study analyzes the technical trend of electric agricultural field machinery through product analysis, paper analysis, and patent analysis concerning HEV and EV in the automobile, construction machinery, and agricultural machinery sectors. For product analysis, the homepages of companies in these sectors were consulted to analyze the number of products of each company. For paper analysis, key words related to HEV and EV were selected, a search formula was drawn up, and articles search sites were consulted. And for patent analysis too, key words were selected and then a search formula was drawn up to examine published patent applications or registered patent applications, and trends were analyzed by structure, country, and year. The number of HEV and EV products were 17 in the automobile area, 8 in construction machinery, and 4 in agricultural machinery. Notably, in the agricultural machinery area, all HEV and EV products were from advanced companies overseas. In terms of papers, papers published in the past 5 years were searched and 33,195 papers were from the automobile area, 3,806 were from construction machinery, and 2,687, the fewest papers, were from the agricultural machinery area. A search of patents in the electric drive technology area in Korea, USA, and Japan, and Europe showed 1,927 valid patents, with 1,120 in Japan, 497 in USA, 193 in Korea, and 117 in Europe. Analysis of the trend of research on electric agricultural field machinery by product, paper, and patent shows the development of HEV and EV technology in Korea is insufficient compared to USA, Japan, and Europe, which means rapid technological development is needed.

Digital twin is considered as a key technology of industry 4.0, thus being essential for the future of industrial production. Despite the significance, a systematic analysis of its technological landscape is lacking. This study aims to investigate the technological development trends and newly emerging technological convergence opportunities in the domain of digital twin by exploiting patent information derived from U SPTO. For this purpose, this study visualized and predicted the convergence dynamics among patent classification codes by adopting patent co-classification analysis and link prediction approach. The findings show that the number of digital twin-related patent applications has increased significantly since 2018. The CPC code G06F showed the highest eigenvector centrality, while G05B was characterized by highest betweenness centrality. According to the predictive model, 41 novel links were revealed, acting as potential technology convergence opportunities. These links were then categorized into 11 different domains. The most dominant category was "digital data processing and artificial intelligence", which could play a foundational role in the diffusion of digital twin technology. The presence of digital twin technology is dominant in manufacturing, but its applications are expected to expand, including "climate change", "healthcare" and "aerospace engineering". The derived insights can support R&D managers and policy makers in formulating R&D strategies and directing future R&D investment decisions.

Utilizing the patent application data between 1997 and 2002, this study focuses on analysing the impact of patents on firm value. Especially we attempt to examine the difference of patents between venture firms and general firms. This paper first shows that the number of the patent applications of general firms listed on the securities market is more than that of venture firms listed on KOSDAQ. It is thought that this result is originated from the facts that the size of firms of the securities market is usually bigger than that of the firms of KOSDAQ and that these large firms could manage R&D more efficiently. Second, this paper reports that there is no difference in the ratio of patent maintenance between venture firms and general firms. Both venture firms and non-venture firms would do their best to keep their patents after patent regisration. Third, in the regression of patent index and firm growth, we find that the excellence of patent and the number of patents per employee would have an impact on the growth of firms. Fourth, the regression of patent index and profitability shows that the excellence and the number of patents per employee might have an effect on the profitability of firms.

본 연구는 화웨이의 PCT 특허 출원 동향을 분석하는 것을 목적으로 하였다. 화웨이의 PCT 특허를 2000년대 초반, 2000년대 후반, 2010년대 초반으로 나누어 분석한 결과, 다음과 같은 세 가지 특징이 관찰되었다. 첫째, 2000년 초반에서 후반으로 들어서면서 PCT 특허 출원건수가 급격하게 증가했으며, 이 증가 추세는 2010년대 초반에도 이어졌다. 둘째, 집중했던 기술 분야는 2000년대 초/후반에는 'H04L: 디지털 정보전송(transmission of digital information)'이었지만, 2010년대 초반에는 'H04W:무선 통신 네트워크(wireless communication networks)' 로 변화하였다. 마지막으로, 특허맵 분석 결과 2000년대 초/후반에는 '사용자', '네트워크'와 관련된 일반적인 통신 기술이 주를 이루었다면, 2010년에는 '사용자 단말기', '기지국', 'MME'와 같은 이동전화 관련기술이 보다 활발히 개발되었음을 알 수 있었다. 특히 최근에는 화웨이가 4G의 주류 기술인 LTE 관련 특허 출원에 있어 애플, 삼성보다 더 적극적임을 고려할 때, 향후 글로벌 시장에서 더 큰 기술적 영향력을 지닐 것임을 시사한다.
