  • This study analyzes the technological structure of artificial intelligence (AI) and technological capabilities of AI companies based on patent information. 2589 AI patents registered in USPTO from 2007 to 2017 were collected and analyzed by the Latent Dirichlet Allocation (LDA) to derive 20 AI technology topics. Analysis of technology development trends by AI technology reveals that visual understanding, data analysis, motion control, and machine learning are growing, while language understanding and speech technology are sluggish. In addition, we also investigated leading companies in each sub-field of AI as well as core competencies of global IT companies. The findings of this study are expected to be fruitfully used for formulation and implementation of technology strategy of AI companies.

  • Patents for postharvest technology of fresh fruits, vegetables and mushrooms fluctuated in their filing number until the 2000s, but then there has been a steady increase in the 2010s, indicating that the technology has high growth potential in the international agricultural market. Using 551 valid patents for fresh fruits and 337 for fresh vegetables of 5 countries, patent trend of postharvest technology was analyzed in this study with two categorized technologies as packaging and storage. In Korea, patents from national research institutes such as the Korea Food Research Institute and Korea (Rural Development Administration) are dominated, and a number of patents for the postharvest storage of fresh vegetables by Mitsui Chemicals, a Japanese chemical company, have been registered. Agrofresh, a multinational company in the USA, holds a number of patents for postharvest storage of fresh fruit not only in its own country, but also in Japan and Europe. Postharvest technology of fresh fruits and vegetables was found to has a number of patents, mainly from national research institutes and multinational corporations, and this suggests that R&D and commercialization of the technologies are actively taking place.

  • Metal prices are rapidly rising due to increasing demand of metals and limited available resources according to the industrial requirement. As a result, securing a stable supply of these metal resources has been recognized as a core element of national competitiveness and sustained economic growth. In the case of magnesium and its alloys which are entirely depending on import, low-grade magnesium scraps from end-of-life vehicles and 3C(Camera, Computer, Communication) parts and magnesium wastes such as sludge and dross generated during melting process are hardly recycled. Accordingly, the development and commercialization of recycling technology of low-grade magnesium scrap is desperately needed to improve efficiency of resource circulation and to establish the required proprietary of resource metal supply and demand. In this study, papers and patents on recycling technologies of waste magnesium were analyzed. The range of search was limited in the open patents of USA (US), European Union (EP), Japan (JP), Korea (KR) and SCI journals from 1974 to 2012. Patents and journals were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journals was analyzed by the years, countries, companies, and technologies.

  • Because the USV(Unmanned Surface Vehicle) is capable of remote control or autonomous navigation at sea, it can secure the superiority of combat power while minimizing human losses in a future combat environment. To plan the technology for the development of USV, the trend analysis of related technology and the selection of promising technology should be preceded, but there has been little research in this area. The purpose of this paper was to measure and evaluate the technology trends quantitatively. For this purpose, this study analyzed the technology trends and selected promising/declining technologies using topic modeling of papers and patent data. As a result of topic modeling, promising technologies include control and navigation, verification/validation, autonomous level, mission module, and application technology, and declining technologies include underwater communication and image processing technology. This study also identified new technology areas that were not included in the existing technology classification, e.g., technology related to research and development of USV, artificial intelligence, launch/recovery, and operation, such as cooperation with manned and unmanned systems. The technology trends and new technology areas identified through this study may be used to derive key technologies related to the development of the USV and establish appropriate R&D policies.

  • With the advance to the knowledge-based economy, science and technology (S&T) has been recognized as key factor in a nation's competitiveness. To cope with this kind of new trend Korean government has tried to increase the R&D investment and to streamline acts and regulations concerning national R&D activities. Korea's total R&D expenditure for the year 2007 amounted to about 31.3 trillion won including government R&D of 8.9trillion won. With these efforts the capacity of Korea S&T has made great strides recently. Korea was ranked world's top 7 in R&D investment, top 12 in S&T paper publication and top 4 in patent application. Korean government enacted several pieces of legislation concerning S&T : the "Technology Transfer Promotion Act (1999)"; the "Framework Act on Science and Technology (2000)"; and the "Presidential Regulation for Managing the Government R&D Programs (2001)." In addition, the government has put a lot of effort into promoting the commercialization of technologies developed in public sector and improving the infrastructure of technology transfer and commercialization. However in spite of these various efforts, the technologies obtained from the public sector have not been transferred to the industry properly. Only 24.2% of technologies developed in the public for the year 2005 were transferred to industry. The royalty revenues of the public for the year 2005 was 1.5% of their total R&D expenditure. It shows only a third of the percentage of royalty revenues for the public sector in the U.S.A. and a second of Europe. There are many obstacles of public technology transfer such as immaturity of technology market, lack of licensing experience, and inadequacy of legal system and government policy. In this study I compared the Korean legislative system of patent management of government R&D outputs with the American system, derived problems from Korean system, and suggested proper alternatives.

  • This paper analyzes the trends in generative AI technology based on patent application documents. To achieve this, we selected 5,433 generative AI-related patents filed in South Korea, the United States, and Europe from 2003 to 2023, and analyzed the data by country, technology category, year, and applicant, presenting it visually to find insights and understand the flow of technology. The analysis shows that patents in the image category account for 36.9%, the largest share, with a continuous increase in filings, while filings in the text/document and music/speech categories have either decreased or remained stable since 2019. Although the company with the highest number of filings is a South Korean company, four out of the top five filers are U.S. companies, and all companies have filed the majority of their patents in the U.S., indicating that generative AI is growing and competing centered around the U.S. market. The findings of this paper are expected to be useful for future research and development in generative AI, as well as for formulating strategies for acquiring intellectual property.
