In order to make a decision about the acquisition of command control communication weapon systems considering the client's technology level requirements, the improvement of the domestic technology level and security of core technology, the person in charge can perform technology evaluation/analysis based on command control communication weapon system patent data. As a method of collecting such patent data, we can collect the patent data of government-designated (Defense Acquisition Program Act Article 35) companies (11 Major defense companies/9 General defense companies) through the Korea Intellectual Property Rights Information System (KIPRIS) of the Korean Intellectual Property Office (KIPO) In this way, we collected 1,526 patents and 134 International Patent Classification (IPC) types through the KIPRIS of the KIPO. Based on these data, we performed three types of analysis, General information analysis, Principal Components Analysis (PCA) and Network analysis, and extracted 27, 19 and 13 IPC types from them, respectively. Based on the above three analysis results, we confirmed 8 IPC types (F41A, F41G, G06F, G01S, H04B, H04L, H04M and H04W) as the key technologies and representative technology fields of domestic communication-electronics defense companies.

With the explosively increasing intellectual property rights, securing technological competitiveness of companies is more and more important. In particular, since patents include core technologies and element technologies, patent analysis researches are actively conducted to measure the technological value of companies. Various patent analysis studies have been conducted by the International Patent Classification(IPC), which does not include the latest technical classification, and the technical classification accuracy is low. In order to overcome this problem, the Cooperative Patent Classification(CPC), which includes the latest technology classification and detailed technical classification, has been developed. In this paper, we propose a model to analyze the classification of the technologies included in the patent by using the detailed classification system of CPC. It is possible to analyze the inventor's patents in consideration of the relation, importance, and efficiency between the detailed classification schemes of the CPCs to extract the core technology fields and to analyze the details more accurately than the existing IPC-based methods. Also, we perform the comparative evaluation with the existing IPC based patent analysis method and confirm that the proposed model shows better performance in analyzing the inventor's core technology classification.

A technology is continuously developed in a rapidly changing global market. A company requires an appropriate R&D strategy for adapting to this environment. That is, the technologies owned by the company needs to be thoroughly analyzed to improve its competitiveness. Alternatively, technology classification using IPC codes is carried out recently in an objective and quantitative way. International Patent Classification, IPC is an internationally specified classification system, so it is helpful to conduct an objective and quantitative patent analysis of technology. In this study, all of the patents owned by company C are investigated and a matrix representing IPC codes of each patent is created. Then, a structured association map of the patents is made through association rules mining based on Confidence. The association map can be used to inspect the current situation of a company about patents. It also allows highly associated technologies to be clustered. Using the association map, this study analyzes the technologies of company C and how it changes with time. The strategy for future technologies is established based on the result.

The government-led top-down development approach for weapons system faces the problem of technological obsolescence now that technology has rapidly grown. As a result, the government has gradually expanded the corporate-led bottom-up project implementation method to the defense industry. The key success factor of the bottom-up project implementation is the ability of defense companies to plan their technologies. This paper presented a method of analyzing patent data through data mining technique so that domestic defense companies can utilize it for technology planning activities. The main content is to propose corporate selection techniques corresponding to the defense communication-electronics sectors and conduct principal component analysis and cluster analysis for the International Patent Classification. Through this, the technology was classified into four groups based on the patents of nine companies and the representative enterprises of each group were derived.

Biotechnology is considered a new propeller to national economic growth. Although BT-based converging technology is one of keywords in nowadays, few studies analyze the characteristics of Korean BT convergence market. This study has conducted the analysis of BT-based converging technology market by using patent database in KIPO (Korean Intellectual Property Office) from 2000 to 2010. We, especially, have classified BT convergence into homogeneous and heterogeneous ones, and compare the nature of BT convergence market with that of non-convergence one. To achieve the object of this study, the following methods are used: concentration across IPC technological classes; concentration of patenting activity across firms; PFS (Patent Family Size) index. Furthermore, according to FOS technology-industry table, we have intended to find new converging industry of BT heterogeneous converging technologies. As very few studies have focused on Korean converging technology market so far, this analysis is considered to be meaningful. It is found that the market of BT converging technology is rather robust than that of BT non-converging one, which refers that BT convergence shows the tendency of concentration towards few technologies by few conglomerate firms in Korea. Meanwhile, we have derived a BINET keyword map to research the convergence of sub-technologies in detail and the related industries. We expect the implications of this study to be utilized in establishing the BT-based converging technology policy.

4차 산업혁명의 도래와 더불어 ICT 기계, ICT 금융, ICT 의료, ICT 나노 등과 같이 기술분야별 영역의 장벽이 허물어지고, 학제간 연구(Interdisplinary Research)가 일상화됨에 따라 무형자산의 가치평가시에도 융합기술의 가치평가 모형에 대한 니즈가 증대되고 있다. 특히, 기술의 매매, 현물출자, 기술금융(투자유치, 담보 보증), 인수 합병, 청산 소송 등 다양한 용도로 사용되고 있는 기술가치평가 모형은 융합기술의 입력변수 결정에 대한 체계적인 로직을 제공하지 못하고 있는 실정이다. 일반적으로 실제 거래사례가 존재할 경우, 국제가치평가기준(IVS)에 의하면 시장접근법이 우선적으로 적용될 수 있다고 권고된다. 그러나 융합기술의 이전거래를 비롯한 평가 활용사례를 수집하기도 어렵고 그렇다할 평가모델이 존재하지 않는 것이 사실이다. 융합기술에 대한 기술 및 시장의 사업화 환경을 고려하는 경우 소득접근법 기반의 평가기법이 유용하게 활용될 수 있는데, 기술수명, 매출액추정, 할인율, 산업기술요소 등의 핵심변수 결정에 관한 정형화된 로직이 존재하지 않으므로 본 고에서 융합기술 사례에 대해 실용적으로 활용가능한 변수추정 로직을 제시하고자 한다. 기술수명의 경우, 복수 개의 국제특허분류(IPC)별 피인용특허수에 따라 가중 적용하여 수명 추정을 위한 기준값을 정하며, 사업화소요기간 및 비용의 경우 평가대상 융합기술이 속하는 업종별 메타데이터값을 가중평균하여 현금흐름 추정기간을 최종 도출할 수 있다. 소득접근법에서의 매출추정, 할인율, 산업기술요소 변수 추정 이외에도 로열티공제법 적용을 위한 로열티율 결정에 있어서, 융합기술이 응용가능한 산업(업종)별 매출액 기반으로 가중 적용하여 각 변수값을 산출할 수 있다. 본 연구에서 개발된 융합기술 가치평가 모형은 향후 기술의 융복합화 특성을 반영하여 적정 가치를 산출하는 평가 가이드라인을 제공할 수 있을 것으로 기대된다.
