Patent indicators were used to analyze the movements of local industries in order to derive blank technologies due to rapid changes in technology in the 4th Industrial Revolution and to discover promising technologies. Currently, Changwon-si is gathering a lot of technical information to develop hydrogen electric vehicle technology as a future regional flagship industry to discover it as a promising technology in the future. Collecting technical information has many problems in terms of time and cost due to classification methods, technical trends, and similar technologies. Therefore, a systematic classification of technical information and a method for easily deriving technical trends are needed. In this paper, we analyzed the blank technology and promising technology trends for the future core industries of the region through the method of measuring the growth rate of patents and the frequency of patent application through the patent indicators.

Recently patented rights affect the competitive power of each country. Specially the situation of that country will be superiority if one country has lots of basic invention patents in advanced technology. In the near future, research results in universities or research institutes should be involved with patent application so that the investment of research funds improves our technology. Alloy is used to adjust magnetic characteristic in invention for magnetic recording medium. In this case there must be cautious in make out the patent claims of invention about such alloys. The patent for alloy invention is considered with following standard. (1) composition range and structure aspect according to the need of a composition metal (2)characteristics of the alloy and for use.
