As the domestic animation industry is shrinking, it is time to actively respond to changes in new technologies and animation production methods. From 2016 to 2020, through patent information registered in the United States, China, and Korea in the field of animation technology, applicants who are the subject of technology were analyzed and technical policies and strategies pursued by applicants in each country were reviewed. China registered the most patents, so the technical activity index was high, and the US family patent size was high. As a result of positioning analysis, the U.S. market expansion influence decreased over time, China's technological activity gradually increased over time, and Korea's technological activity and family patent size decreased. Reflecting China's rise as the world's largest animation producer, Korea should also develop a policy to support animation.

This paper analyses the effects of R＆D investment on patent in Korean manufacturing firms during the period 1984-99. The data contains 140 companies which listed in Korea Stock Exchange(KSE). We observed that the relative shares of R＆D investments and patent applications are much higher in scientific firms than in the other firms. The regression results show that R＆D investment has significantly positive effects on the growth of patent application and registration. And the effects of R＆D on patent turns out to be stronger in scientific firms than the other firms. The firm size and the capital intensity also have an important effect on the propensity to patent.

While there is a high prevalence of patent foramen ovale in adults, paradoxical embolism via a patent foramen ovale is rare. Previous echocardiographic studies indicated that paradoxical embolism might only occur in patients with high-risk features of patent foramen ovale (i.e., large defect size, presence of a Eustachian valve, and high right atrial pressure). Here, we present a case of patent foramen ovale with high-risk CT features for paradoxical embolism.

The Schizandra chinensis (Korean name : omija) is a fruit native to northeast Asia that is cultivated in South Korea and China. Using 1,938 valid patents of 6 group countries, we analyzed the patent trend based on year, countries, applicants, and technology. The technologies are categorized the 10 sub-technologies such as medicine, quasi-drugs, food, feed, cosmetics, cultivation, genome, manufacture, preprocessing, and etc. The technology level and competitiveness are analyzed using patent index such as cites per patent, patent impact index, patent family size and technology strength. In Korea, patent number rapidly increasing and individual technical level is lower than other countries. However, overall technical competitiveness is estimated high due to multiple patents. We suggest that cosmetics and cultivation fields are most likely to be developed in future omiza technology development in Korea. Our study will provides to the information of technical trend to support performing of new projects for omija plant.

Utilizing the patent application data between 1997 and 2002, this study focuses on analysing the impact of patents on firm value. Especially we attempt to examine the difference of patents between venture firms and general firms. This paper first shows that the number of the patent applications of general firms listed on the securities market is more than that of venture firms listed on KOSDAQ. It is thought that this result is originated from the facts that the size of firms of the securities market is usually bigger than that of the firms of KOSDAQ and that these large firms could manage R&D more efficiently. Second, this paper reports that there is no difference in the ratio of patent maintenance between venture firms and general firms. Both venture firms and non-venture firms would do their best to keep their patents after patent regisration. Third, in the regression of patent index and firm growth, we find that the excellence of patent and the number of patents per employee would have an impact on the growth of firms. Fourth, the regression of patent index and profitability shows that the excellence and the number of patents per employee might have an effect on the profitability of firms.

Background: Medicinal plants are widely used in Asia. They have proven to be an invaluable asset in modern drug discovery and their demand has been steadily increasing across various industries. Methods and Results: Using 4,867 valid patents related to 12 oriental medicinal plants of 10 country groups, the growth and development potential of patents was evaluated. The cites per patent (CPP) and patent family size (PFS) indices were used to evaluate the market capability and technological level of the collected patents. Meanwhile, the patent impact index (PII) and technology strength (TS) were used to compare the technological competitiveness of patents among various technology types and markets. Both CPP and PFS indices showed that magnolia-vine and balloon flower have numerous core or original patents. Furthermore, an increase in both PII and TS indices was observed. A newly designed intellectual property multi-layer (IPM) model predicted that the medicine, genome and cosmetic categories have a high possibility of patent application growth. Conclusions: The IPM model can be used to provide the scope of particular technology fields for patent development. In addition, this study can assist patents to advance in the international market and guide the development of a national industrial strategy.

In light of the fact that the effect of intellectual property rights like patent on enterprise competitiveness is growing, rational valuation of patent rights, which are own by enterprises, is required because accurate patent valuation can bring about the activation of the technology exchange market and enhancing the values of enterprises as well as the security of funds through technology security. However, in reality, interest in the value of patent rights is not great due to many variables, affecting patent rights, and diverse attributes, and non-generalized methods of valuation. Therefore, studies on patent valuation for patent management of Small and Medium Enterprises is required. This thesis examined patent valuation for the patent management of Small and Medium Enterprises based on literature studies, and attempted to find factors, affecting patent valuation by finding patent valuation factors through experts, organizing, and analyzing these factors. 10 essential factors, which are demonstrated in this research, are the commercialization possibilities of technology, market competitiveness, the possibility of technology commercialization, market size, the originality of acquired technology, the stability of the right(the possibility of invalidating), the level of technology, technology competitiveness, the ripple effect of technology, and the characteristics of technology(original technology/application technology).

This study analyzed the trends of patents for unmanned technology used in agriculture. The target countries for this survey of patent data were Korea, the USA and Japan as well as the countries in Europe. The indices used in this study to analyze the patents were the CPP (Cites Per Patent), PII (Patent Impact Index), and PFS (Patent Family Size). The total effective patents for unmanned technology used in agriculture were 1,080 cases. The number of patents in the USA, Japan, Europe, and Korea were 541, 326, 128 and 85 cases, respectively. Among the total effective patents, the evaluation scores for selected important patents were calculated by applying commonly used weights to each index, and the top 10 patents were selected as important patents. The results showed that all the top ten patents are owned by the United States and that the United States is an advanced country in the field of unmanned technology used in agriculture. The evaluation score of the important patents using the existing method was biased toward the PII index among the three patent evaluation standards, and the effects of the number of claims and the PFS were relatively small. Therefore, a reliable patent analysis in the field of unmanned technology used in agriculture needs to reflect the overall evaluation factors taking into consideration the scope of the evaluation factors.
