Geophysical prospecting technologies are employed to environmental site assessments and monitoring, subsurface investigation, geologic hazard monitoring since they are able to provide information and imaging regarding the subsurface. In this study, we carried out several analysis on patent documents for the geophysical prospecting technologies. The patents including abstracts, claims and drawings from 1976 up to 2005 were surveyed and 904 patents were collected finally. The patents were investigated as to countries, years, assignees and technologies. Furthermore, we carried out the comparative analysis for technological level of assignee countries with United States patents. The top 5 assignee countries are United States, United Kingdom, Japan, Norway and France. Especially United States and United Kingdom play important role in this area as holding 663 patents.

For the human body shape information, body measurement techniques using a tape measure or image analysis are used. However, there is a demand for a method with high measurement accuracy and reproducibility while being simple. In this paper, domestic and foreign patent research related to body size measurement technology was conducted to identify the development trend of the related technology. WISDOMAIN DB was used to search for patents published in Korea, the United States, Japan, and Europe, and valid patents were derived by defining the technical scope of major and medium classifications and sub-categories. For the derived patents, patent trends by year, major applicants by country, and the status of technological fields were analyzed. In the field of body size measurement technology, the proportion of patent applications filed in Korea is high, indicating that Korea is leading the patent application in this field. Although the number of patent applications in the field of sensor-type measurement technology was not large, it has an advantage in measurement simplicity, so the development of related technology is expected to contribute to the improvement of measurement accuracy related to body composition analysis.

Video surveillance industry as a high-tech industry has traits that a pace of source technology development is slow while a pace of application technology development is fast. Unlike domestic companies have shown technological excellence in the field of video surveillance hardware, global leading companies are leading technologies in the field of intelligence video surveillance which would lead the future of the industry. Therefore, technology selection of the domestic companies determines the viability of the company with respect to the terms of market competitiveness reinforcement. In order to achieving this, find out the technology areas where the global leading companies are focused on analysis of global patents. After global patents analysis, identify the status of domestic technologies and analyze the difference between the global leading companies and the domestic companies. Decompose the technologies by element technology-application matrix which is obtained through a panel discussion of domestic SMEs' CTO, CEO, or other experts, they derive the necessary R&D opportunity technologies to ensure the future competitiveness of the company.

This study aims to establish an efficient future technology development strategy in the information and telecommunications industry by grasping related technology trends and fusion complexity through an analysis based on standard patents. Analyzing 1,983 patents related to the information and telecommunications industry identified the trends in major patent applicants and detailed technologies in the world. In addition, technology trends were investigated through keyword analysis to examine the degree of complexity in information and communications technology, confirming the direction of research in information technology. Electronic component and wireless communications fields have relatively few standard patents, but they are highly convergent with other industrial technologies. Computer information processes and communication and broadcasting technologies are highly related to each other, so they can be used as standard fusion technologies in standard patents. In addition, standardization activities in optical and image/sound devices are found to be high.
