This study is the basic research about the patent information analysis to predict the technology trend based on the IPC(International Patent Classification) code. We investigated the patents in the field of Business Method(G06Q) since 2011. Consequently the most frequently IPC code in G06Q are as follows. G06Q 50/10(1,652), G06Q 30/02(816), G06Q 50/30(735), G06Q 40/02(713), G06Q 50/22(530), and G06Q 30/06(489).

The ICT technology by using smartphone is leading the world. Apple opened the smart age with its smartphone on the first place in the world. In 2013, Samsung of Korea is spotlighted in the world, but China will run after Samsung with medium- and low-priced smartphones equipped with functionality and low and medium prices after 2014. That is, the life cycle of ICT technology gets shorter, and the volume of investment is increased. There is increasing uncertainty of enterprises and nations because the expanded volume of investment. Therefore, it is very important to predict emerging ICT technology, and investment development. Korea based on the creative economy is at the point of strengthening ICT. Therefore, this study aims to analyze intellectual property rights (patent) and the ICT market environment for the emerging ICT technology. The result of analysis will contribute to studying the intellectual property rights (patent) and the R&D matrix module in the ICT market environment for discovering and predicting national emerging ICT technology.

Parkinson's Disease (PD) is one of the three major old-age onset neurodegenerative diseases, its incidence rate is increasing worldwide as being an aging society. The number of PD patients has increased from 3 million in 1990 to 6.2 million in 2015 and is expected to increase to 12.4 million by 2040. Although many therapeutic candidates have been under development, but not yet been suggested the therapeutics of PD. For analyzing the trends and the status of convergence of technologies in the PD therapeutics, we classified into six sub-categories using global patent information and analyzed the level of technical competitiveness and technology convergence according to year, country, applicant, and technical description. These results can be used as a fundamental understanding for the current technical trend and the status of convergence of PD therapeutics, and establish the direction and strategy of R&D.

Objective : To build a basis of patent analysis for development of Korean ginseng as a competitive medical product in the world market. Methods : Survey of all patents related to ginseng or ginseng products in Korea and other rival countries such as the USA, Japan or EU, using KIPRIS. Results : Korea has more patents of ginseng itself , however has fewer patents related to functional goods, higher value-added businesses or medical technologies using ginseng than rival countries. Conclusion : The Oriental medical world should make more effort to verify the pharmacological effects of ginseng, develop high value-added functional products or medical technologies using ginseng and apply for more patents in such fields.

This study attempts to explore the difference of innovation sources between high-tech industry and mid-tech industry through patent analysis. After extracting 119 corporates, commonly surveyed in 2007 HCCP(Human Capital Corporate Panel) and 2005~2006 Korea Innovation Survey, their patents applied for the Korean Intellectual Property Office in 2007~2012 are analysed mainly through negative binomial regression model. Analytical results shows that external information source could be opposite effects to technological innovation depending on technological level and industrial characteristics. The current results are still bounded in the statistical significance, mainly due to the limited observations and information.

This study aims to find the major creative ideation patterns embedded in the commercially valuable patents in the mobile communication industry. For the purpose, we analyze 171 cases of the patent infringement lawsuit filed by Nokia in the United States. It is examined that what kind of TRIZ inventive principles and SIT thinking tools were applied to resolve technical contractions in each of the 171 cases respectively. Among the 40 inventive principles of TRIZ, 'feedback' principle was used mostly and 'division' principle the next. Among the 5 thinking tools of SIT, 'attribute dependency' mostly used, and 'division' the next. This suggests that what kind of inventive principles or thinking tools should be considered preferentially to resolve technical contradictions in practically important technical problems in the mobile communication industry.

Within the framework of brake-by-wire technology, this paper presents five types of novel models of electro-mechanical disk brake calipers with self-servo mechanism which provides self-servo effect of boosting a friction force generated between the brake pad and the rotor disk surface. The models have been developed utilizing patent map analysis results of previous invents of electro-mechanical brake calipers. The feasibility of the developed motor-driven brake caliper models have been validated through the dynamic simulation analysis. Among the developed models, the caliper mechanism with separated pressure plate was designed especially in detail and was made as a pilot. The pilot caliper has been installed on the simple test bed constructed with domestic passenger car brake components, and its function and effectiveness have been validated through several types of experimental tests.

Recently, the notion of National Innovation System (NIS) has attracted considerable attention as a key driver of the economic success. Amongst others, the Northeast Asian countries deserve highlight as central cases of NIS. This research attempts to examine inter-industrial knowledge flows and structure among Northeast Asian countries. To this end, Korea, Japan and Taiwan are selected and the patent citation data, a proxy of disembodied knowledge flows, from United Stated Patents and Trademark Office (USPTO) are employed for cluster analysis and network analysis. Some meaningful findings are presented and distinctive characteristics of respective countries are contrasted.

To accommodate various mobile communication frequency bands, the study of metamaterial antennas have begun since the mid-2000s to solve the Trilemma problem between antenna gain-occupied bandwidth-size. As an adaptive reconfiguration function is required in a multi-array antenna system since 4G, the metamaterial array antenna using low-power variable elements has been used to change the basic structure of the antenna. Recently, reconfigurable intelligent surface (RIS), which is made of metasurface with reconfigurability, has been studied to effectively cope with the randomly varying radio channels and be used for various purposes such as reflection/transmission/modulation. As a result of RIS-related patent information analysis in this study, it was confirmed that most of the patents are metamaterial antennas and metamaterial array antennas, but the metasurface antenna technology was in the early stages. Particularly, as the intelligent metasurface antenna is in a more initial stage, the investment to R&D of RIS is urgent to secure patent competitiveness in B5G and 6G.
