글로벌 폴더블 디스플레이 시장은 최근 업체들 간 치열한 경쟁이 벌어지고 있어, 정확한 기술 동향 분석을 통한 전략적 기술기획이 요구되고 있다. 기술기획을 위한 분석 방법으로서의 특허분석은 그 개방성, 정형성, 기술에 대한 상세정보 등의 데이터 특성으로 인해 현장에서 자주 활용되고 있다. 그런데 이 가운데 정성분석은 특허의 내용을 건별로 파악하여야 하는 관계로 시간과 비용의 문제가 발생하며, 전통적인 정량분석은 주로 특허의 수에 의존함으로써 특허의 내용 및 기업별 핵심기술을 파악하는 데 한계가 존재한다. 따라서 본 연구에서는 특허의 동시분류 네크워크 분석 방법을 활용하여 기업별 핵심기술을 분석해 보고자 하였다. 분석 결과, 폴더블 디스플레이 관련 특허 출원은 2014년부터 급격히 성장하여 출원 기업의 92%가 한국의 2개 패널 제조사(SDC 및 LGD)와 2개 세트 제조사(SEC 및 LGE)의 출원으로 확인되었다. 동시분류 네트워크를 분석해 본 결과, 패널 제조사인 SDC와 LGD는 핵심기술 분야가 서로 유사한 반면, 세트 제조사인 SEC와 LGE는 눈에 띄는 차별성이 존재함을 확인하였다. 이러한 결과는 본 분야 기업의 기술전략에 대한 시사점을 제공한다. 또한 특허 동시분류 네트워크를 통해서만 확인이 가능한 것으로, 이 분석이 기업 기술전략에 유용하게 활용될 수 있음을 확인하였다.

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.

This study identified technological trends through an analysis of patents for the industrialization of personal protection and convenience equipment using information and communication technology (ICT) as a part of efforts to prevent farm work-related disasters. The analysis was conducted on patents registered and published between January 1974 and May 2016 by the world's five largest intellectual property offices, including the KIPO, USPTO, JPO, EPO, and SIPO. The results of the analysis indicate that the US (36.8%) and South Korea (30.9%) led technological research and development (R&D) with frequent patent applications. An analysis of the technological market revealed that these countries are in the growth and maturity stages, in which the number of patents and number of patent applicants grow rapidly. In terms of the technological market shares of major countries, the US recorded the highest market shares in the field of sensing systems for workers' dangerous conditions and convenience protection equipment based on the internet of things (IoT) convergence. South Korea marked the highest share of 41.8% in the field of sensing devices for dangerous conditions in the working environment. An analysis of the trend of patent applications by specific technologies disclosed the following results: sensing systems for workers' dangerous conditions accounted for the highest share (49.2%), followed by IoT convergence-based convenience protection equipment (26.3%) and sensing devices for dangerous conditions in the working environment (24.6%). Based on this study, ICT-based personal protection and convenience equipment technologies are expected to be actively developed in the future. It will be necessary to secure national competitiveness through R&D investments and commercialization in personal protection and convenience equipment appropriate for farm work as well as through the acquisition of patent technologies and intellectual property rights.

지금까지 특허분석에 관한 연구는 특허지도(Patent Map; PM)분석을 수행하여 기술동향을 분석하고 있으나, 주제에 대한 검색결과를 엑셀 등을 이용하여 그래프화하여 출원빈도에 대한 추이를 나타내는 것이 대부분이다. 이러한 분석은 특정주제에 대한 것으로 국가의 산업이나 국제적인 산업의 동향을 직접 비교 분석하기에는 미흡한 실정이다. 본 연구에서는 PM분석의 신뢰성을 높이기 위해 통계분석의 필요성을 제시하고, 1990년부터 2004년에 출원된(출원번호 기준) 한국특허 전체를 대상으로 연도별, 분류별(IPC Section 분류)로 각 국가(한국, 미국, 일본, 독일)의 출원빈도를 통계적으로 유의한 수준을 분석하였다. 또한 국가 및 기술 분류에 대한 출원빈도에 대해 포아송 회귀분석을 수행하고, 통계 적으로 유의한 수준에 따른 평가를 R&D에 활용할 수 있도록 하였다.

Background Innovation has molded the current landscape of plastic surgery. However, documentation of this process only exists scattered throughout the literature as individual articles. The few attempts made to profile innovation in plastic surgery have been narrative, and therefore qualitative and inherently biased. Through the implementation of a novel innovation metric, this work aims to identify and characterise the most prevalent innovations in plastic surgery over the last 50 years. Methods Patents and publications related to plastic surgery (1960 to 2010) were retrieved from patent and MEDLINE databases, respectively. The most active patent codes were identified and grouped into technology areas, which were subsequently plotted graphically against publication data. Expert-derived technologies outside of the top performing patents areas were additionally explored. Results Between 1960 and 2010, 4,651 patents and 43,118 publications related to plastic surgery were identified. The most active patent codes were grouped under reconstructive prostheses, implants, instruments, non-invasive techniques, and tissue engineering. Of these areas and other expert-derived technologies, those currently undergoing growth include surgical instruments, implants, non-invasive practices, transplantation and breast surgery. Innovations related to microvascular surgery, liposuction, tissue engineering, lasers and prostheses have all plateaued. Conclusions The application of a novel metric for evaluating innovation quantitatively outlines the natural history of technologies fundamental to the evolution of plastic surgery. Analysis of current innovation trends provides some insight into which technology domains are the most active.

This study analyzes not only the direct impact of R&D investment on corporate growth for 578 private firms in 2007-2016, but also whether corporate innovation activities play a role as a mediating parameter between R&D investment and corporate growth. For this purpose, we classify companies into IT and non-IT companies and measure the mediating effect by dividing innovation activities into the number of registered patents, applied patents, and sum of them. In addition, this study is based on both the systemGMM which is considered to be effective in solving the endogenous problems caused by the cross-sectional analysis in previous studies and ML-SEM which is a new method recently, and then compares two results. According to the empirical results, innovation activities has a role as partly mediating parameter on sales growth in non-IT companies. On the other hands, in IT companies, the increase in R&D investment leads to a decrease in sales of the company, and the increase in innovation activities increases the sales of the company. However, it was confirmed that IT companies also had positive effects by adjusting the lag of the R&D. In other words, this suggests that securing patents is more important than R&D investment for direct sales growth of IT companies. It is also evidence that immediate introduction of technology is necessary to respond to the speed of technological change since the cycle time of technologies of the IT field is relatively shorter compared to that of other fields.
