The increasing number of technology transfers from public research institutes in Korea has led to a growing demand for patent recommendation platforms for SMEs. This is because selecting the right technology for commercialization is a critical factor in business success. This study developed a patent recommendation system that uses technology transfer data from the past 10 years to recommend patents that are suitable for SMEs. The system was developed in three stages. First, an item-based collaborative filtering system was developed to recommend patents based on the similarities between the patents that SMEs have previously transferred. Next, a content-based recommendation system based on TF-IDF was developed to analyze patent names and recommend patents with high similarity. Finally, a hybrid system was developed that combines the strengths of both recommendation systems. The experimental results showed that the hybrid system was able to recommend patents that were both similar and relevant to the SMEs' interests. This suggests that the system can be a valuable tool for SMEs that are looking to acquire new technologies.

A turbo engine is used to improve engine volumetric efficiency by using the energy of exhaust gas with a device such as a turbocharger. Recently, it has been attracting attention as a solution for responding to environmental issues such as exhaust gas regulation, and its use is being expanded to gasoline and CNG engines as well as diesel engines. However, as electric and hydrogen vehicles enter the automotive market more rapidly, traditional turbo engines also confront many challenges. In this paper, to examine the current status and prospects of the turbo engine, we analyze the related patents in the turbo engine field applied to patent offices in seven major countries, including Korea, USA, China, Japan, Germany, France, and the European Union Patent Office, and analyze the patent application trend. Using ‘the pie’ system of Korea Institute of Science and Technology Information (KISTI), family patents were refined, patent application trends were diagnosed, and the technology and market competitiveness of major applicants were compared and analyzed. Even within the turbo engine market, where traditional automakers and turbocharger manufacturer participate, it was possible to examine the dynamic changes in the market through the analysis of technology and market competitiveness. The main companies leading the technology and market aspects and the companies specialized in the technology and market aspects were observed.

우리나라에서 빅데이터 분석 기술과 특허 소송에서 활용 가능한 지식재산 서비스 또는 법률 서비스 사이의 격차를 줄이기 위한 방안을 제안하였다. 지식재산 서비스에서 국내 기업은 해외 기업과 비교하여 데이터의 양과 질적인 측면에서 열세에 있으므로 국내의 지식재산 서비스를 제공하는 기업들은 데이터에 대한 정보처리 기술을 고도화하여 경쟁력을 확보할 필요가 있다. 또한 특허 빅데이터 분석 기법에 관한 다양한 연구를 활용할 수 있는 알고리즘과 데이터를 오픈소스 방식으로 공개할 수 있는 플랫폼을 제공하여 연구결과의 활용성을 강화할 필요가 있다. 지식재산 서비스의 활용도를 높이기 위해서는 데이터와 알고리즘에 대한 객관성과 투명성이 확보되어야 할 것이다. 법률 서비스에서는 법률산업 선진화와 신성장 동력 발굴 차원에서 리걸테크 산업을 육성하기 위한 산업투자 및 기반 확충에 나서야 한다. 또한 적정한 수준의 비식별화가 이루어진 판결문에 대해서는 연구자들이 손쉽게 접근할 수 있는 데이터베이스 구축이 필요하다. 우리나라는 영미법과 달리 디스커버리 제도가 존재하지 않고 기본적으로 성문법주의를 채택하고 있는 점을 감안하여 판결문 검색을 위한 공공 서비스 등 우리나라 제도에 필요한 부분에 집중할 필요가 있다. 현행 변호사법에 따라 비변호사가 빅데이터 분석 기술을 활용하여 유상으로 고객들을 상대로 법률사무를 취급하는 것은 금지된다. 그러나 변호사법 제109조 제1호의 궁극적인 목적이 일반 국민을 보호하기 위한 것임을 고려했을 때 적어도 알고리즘의 투명성과 데이터의 객관성이 확보되는 것을 전제로 변호사가 아닌 개인 또는 기업이 빅데이터 분석 기술을 활용해 법률 서비스를 제공하는 것을 일부 허용할 필요가 있으며 변리사 법에 의한 규제도 마찬가지의 고민이 필요하다.

The technology competitions of automobile manufacturers are getting hot. The characteristics of the environment friendly automobile are not only lowering the emission of harmful exhaust gas through the change of the power source, but also paying great attention to improvement of the power efficiency. As the market for pure electric vehicles continues to grow, we have analyzed the global technology competitiveness by DCT (Dual Clutch Transmission) patents. Clustering can be classified into five types ; 1) a cluster associated with a dual clutch transmission system, 2) a cluster of a torque transmission device and a reverse speed ratio, 3) a cluster of co-planar sets and dual clutch assemblies related to transmitting devices, 4) Device clusters, and 5) a cluster of synchronizers and clusters to prevent simultaneous operation of dual clutch transmissions. In recent years, demand for pure electric vehicles has been rapidly increasing, and patent applications related to DCT have been steadily increasing for energy efficiency of motor power sources.

Using the data of patents granted by USPTO during 2013~2017 from WIPO IP Statistic Data Center, this paper examines the general trend and the main technical fields of international patents granted to Korea, China and Japan. The Patent Activity Index(PAI) was used to analyze the dynamic changes of international patents in the top 5 technical fields. The results show as follows. First, the number of international patent applications and registration by China has been increasing rapidly in recent years. Second, the technical fields of international patents granted by China and South Korea are mainly concentrated in several fields, such as computer technology, semiconductors, digital communication, audio-visual technology and electrical machinery, apparatus, energy. Third, through the PAI index analysis, the technology innovation and concentration of South Korea and China surpassed Japan in telecommunications technology field, and China’s development in the semiconductor field is the strongest. The technological innovation performance of Japan was analyzed as to be relatively higher than that of China and South Korea in the field of electrical machinery, apparatus, energy.

본 연구에서는 국가연구개발사업의 성과물로서 창출되는 특허정보의 거시적ㆍ미시적 분석을 통해 기술혁신 특성을 파악하고자 하였다. 특허성과의 기술군별 비중을 분석한 결과 국가연구개발사업이 IT계열 기술군으로 편중된 것으로 나타났다. 기술군별 상대적인용도지수(RCI)의 분석은 향후 BT계열 기술군이 부상할 것임을 시사하였다. 또한 상대적시장확보지수(RFI)는 BT계열 및 IT계열과 같은 기술적 파급이 큰 기술군에서 높은 것으로 나타났다. 기술 융ㆍ복합화, 연구개발 주체 간의 협력-개방 관계에 대한 신규지표를 설계하고, 네트워크 분석 기법을 활용하여 기술군 사이의 흡수-파생 관계, 연구개발주체 간의 협력-개방 관계를 분석하였다. 이종기술간 기술 융ㆍ복합화가 증가하고 있으며, 상이한 연구개발주체들 사이의 연구개발 협력성과가 급증하고 있는 것으로 나타났다.

This study suggests new approach to identify core technologies through patent analysis. Specially, the approach applied data mining technique and multi-criteria decision making method to the co-classification information of registered patents. First, technological interrelationship matrices of intensity, relatedness, and cross-impact perspectives are constructed with support, lift and confidence values calculated by conducting an association rule mining on the co-classification information of patent data. Second, the analytic network process is applied to the constructed technological interrelationship matrices in order to produce the importance values of technologies from each perspective. Finally, data envelopment analysis is employed to the derived importance values in order to identify priorities of technologies, putting three perspectives together. It is expected that suggested approach could help technology planners to formulate strategy and policy for technological innovation.

Technological convergence is yielding new values and affecting various fields not by single technology but by convergence between technologies. This study aims to analyze the IT -BT-NT convergence and differences between technologies in respect of collaboration within (inventor) and between (assignee) organizations. Among the main technologies leading the technological convergence, IT is the most active of converging with other fields. BT is knowledge-intensive and strong cooperative networks are important in this area. NT is applied in various industrial fields upon the basic technology. Using the data on applied and granted patents by Korean applicants in the U.S., this study conducted quantitative analysis and ANOVA to gain the following results. First, the degree of convergence in between IT-BT-NT is continuously increasing since 2002. Second, BT is where the collaboration within and between organizations is the most active among IT-BT-NT. Third, there were certain differences in the degree of convergence according to the years and the fields of technologies in all the IT-BT-NT. Organizations cooperate with other institutions to sustain their competitiveness with limited internal resources. Companies in these fields are recommended to perform diverse strategies to pursue further collaboration with the outside.
