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.

In this paper, We tried to analyze the patent trend on constitution diagnosis and treatment related technologies. For this, constitution diagnosis and treatment related technologies divided into 16 sub-technology by the advisory committee. And we analyzed patents applied in Korea, Japan, U.S.A., China, and Europe. The 16 sub-technology consist of pulse analyzer, skin diagnosis, tongue analyzer, face and body detector, face analyzer, voice analyzer, intelligence ontology, meridian diagnosis, infrared thermography, electric stimulation, laser, high and low frequency, physical, magnetic, and ultrasound therapy. As a result we found that patents of constitution diagnosis and treatment in Korea has been growing steadily in both quality and quantity since 1980s. The number of patent the pulse analyzer and low frequency therapy are larger than others. But applied relevant international patents, marketability of the patent and Cites per Patent (CPP) index are shown to be very low. In conclusion, to occupy key original technologies of the Oriental medical device, we need to apply more patent of the whole related technology and international patents.

The development of liquid CO₂ storage tanks and liquid CO₂ handling technology are key for liquid CO₂ carriers, and it is necessary to extract core patents of competitors that may lead to patent disputes in the future, establish response strategies, and strengthen the IP portfolio by creating new IPs. As a result of patent analysis for this purpose, patent applications and technology development are being led by the three large domestic shipbuilding companies(Hyundai, Samsung, and Hanwha) and the large Japanese shipbuilding company(MHI), and the handling of liquid CO₂ storage tanks and liquid CO₂ (prevention of dry ice formation) Technology-related patent applications and technology development are actively taking place, so there may be concerns about patent infringement. Currently, It has been confirmed that there are no core patents that are likely to cause patent disputes in the future. However, the technology concept in question lacks patentability as it is a combination of known technologies, so the creation of new IP is necessary to establish exclusive rights. Accordingly, through this project, four new IP creations and patent applications based on competitors' patents were completed. ① Technology to prevent the release of dry ice during unloading using filters, ② Technology to prevent the creation of dry ice in the unloading piping during unloading, ③ BOG reliquefaction technology to respond to CO₂ emission ban regulations, and ④ Technology that can utilize BOG within ships.

Patent and utility indicate international competitiveness in the knowledge-based society of the $21^{st}$century where both the quantity and quality of the nation's scientific intelligence and innovative technology represent key criteria to evaluate its strength. Thus, discerning the trends of patents is inevitable for further development. This research is centered on apprehending the technological current of the functional clothing of Korea, through an analysis of patents and utility models. The number of patent applications in Korea was low until the mid-1990s. However, it began to grow rapidly in the 2000s and the number of patents surpassed the number of utility starting in 2006. The technological level of invention in this field has been turned into a higher level. The IPC code with the strongest application was the field related to temperature controllable clothing (A41D 13/005), followed by surgeon or patient apparel related fields (A41D 13/12), and reflective or luminous safety devices (A41D 13/01).The main technological idea was to give functionality that could protect the human body from various hazards and represents the goal of various applied techniques. About 66% of domestic patent applications belong to individuals; however, the proportion of corporate or institutional applications(including universities) remains poor. Consequently, more systematic and long-term support for research on patents is required.
