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.

It is becoming increasingly difficult to identify promising technologies due to the influx of new technologies and the high level of complexity involved in many of these technologies. Identifying promising information and communications technology (ICT)-based converging technologies holds the key to finding new sources of economic growth and forward momentum. The goal of this study is to identify cutting-edge ICT-based converging technologies by examining the latest trends in the US patent market. Analyzing the US patent market, the most competitive of such markets in the world, can yield certain clues about which of the ICT-based converging technologies may be the next revolutionary technologies. For a classification of these technologies, this study follows the International Patent Classification system. As for ICT, there are 58 related fields at the subclass level and 831 fields at the main-group level. For emerging and converging technologies, there are 75 at the main-group level. From these technologies, a final selection for cutting-edge ICT-based converging technologies is made using a composite index reflecting the converging coefficient, emerging coefficient, and technology impact index.

Forecasting of emerging technology plays important roles in business strategy and R&D investment. There are various ways for technology forecasting including patent analysis. Qualitative analysis methods through experts' evaluations and opinions have been mainly used for technology forecasting using patents. However qualitative methods do not assure objectivity of analysis results and requires high cost and long time. To make up for the weaknesses, we are able to analyze patent data quantitatively and statistically by using text mining technique. In this paper, we suggest a new method of technology forecasting using text mining and ARIMA analysis.

The rapid demand for electric vehicles and energy storage systems has increased interest in energy storage devices worldwide. New technological alternatives are needed to reliably supply energy storage mineral resources such as lithium and vanadium, which are key materials for energy storage devices. Already, research and development activities are taking place in various countries on technologies that can directly secure lithium and vanadium. Accordingly, it is very important to analyze each country's technological trends through patent and paper analysis to establish effective research and development strategies and to set future technological development directions. This study analyzed trends in the development of new technologies and the current status of research and development at home and abroad through patent data from Korea, the United States, Europe, and Japan that were disclosed or registered from 1970 to October 2019, and the data searched for papers from January 2000 to October 2019. According to the analysis, the current growth stage of the technology related to energy storage minerals is in the beginning stage. Therefore, it is believed that a strategy to rapidly upgrade technology by combining the development of new technologies and demonstration of developed technologies is needed in order to lead the technology market and strengthen the competitiveness of technologies.

Innovation is the development of new customers value through solutions that meet new needs, inarticulate needs, or old customer and market needs in value adding new ways. This is accomplished through more effective products, processes, services, technologies, or ideas that are readily available to markets, governments, and society. Innovation differs from invention in that innovation refers to the use of a better and, as a result, novel idea or method, whereas invention refers more directly to the creation of the idea or method itself. Therefore, the utilization of patents is the most important of the three aspects (creation, protection and utilization) in the patent system for getting to actual innovation. In order to increase the patent use, the rates of the applied patents to a real industrial process and the bargain and license of patent rights should be promoted. For promoting technological innovation substantially, there is necessary to escape from dichotomy of weakening or enhancing patent protection in the discussion on the changes of patent system for "Adequate patent guarantees". Furthermore, the legal and institutional improvements to enable the use of patent should be discussed together. Recently, open innovation is a new paradigm that assumes that firms can and should use external ideas as well as internal ideas, and internal and external paths to market, as the firms look to advance their technology" or "Innovating with partners by sharing risk and sharing reward." The boundaries between a firm and its environment have become more permeable; innovations can easily transfer inward and outward. The central idea behind open innovation is that in a world of widely distributed knowledge, companies cannot afford to rely entirely on their own research, but should instead buy or license processes or inventions (i.e. patents) from other companies. In addition, internal inventions not being used in a firm's business should be taken outside the company. In the era of open innovation, more flexible patent use strategy is essential. It is important that improvements for the legal system in order that patented technology can be applied for products and processes in a real industrial between outside and inside of the firms.

To the analysis and discussion whether to conceptualization between the basis and LCM(Life cycle management) of patentability decisions and evergreening through research on patent application strategies and litigation cases. The Stakeholders have said that the LCM and evergreening strategies are an innovative effort to develop new pharmaceuticals, while others say that it is an effort to block generic pharmaceuticals from entering the market and permanently dominate the market by generic pharmaceuticals manufacturers or health economic perspectives. To achieve the goal of research, to discuss for conceptualization LCM and Evergreening strategies through patent application strategies for 14 pharmaceuticals for APIs and case studies for litigations. As a results, the LCM is getting patent rights for the results of research at the initial R&D stage and as such this shall be regarded as part of an effort for technology innovation. However, Evergreening is granting patent rights for the results by making high permission barrier to prevent the market entry of generic pharmaceuticals in the late development period during the pharmaceuticals development process or after their launch. This may lead to the problem of getting weak in health economic aspects and consumer welfare aspects by lowering the market accessibility of cheap generic pharmaceuticals.
