The purpose of this study is to assess the current status of technology development and evaluate future potential by analyzing patent trends in Korea’s fisheries sector. To this end, we examined patent application and registration trends over a 20-year period (2002-2021) within the fisheries domain across the Intellectual Property 5 (IP5) countries (Korea, China, Japan, the United States, and Europe), using data from the Korean Multifunctional Patent Search System (KOMPASS). Based on this analysis, we discussed the strategic direction and marketability of technology development in Korea. Patent applications and registrations in Korea’s fisheries sector have steadily increased over the past 20 years, placing Korea the second among the IP5 countries. Analysis of priority examination data indicates a continuous rise in new technology development, particularly in the aquaculture and seafood. However, multiple-International Patent Classification (IPC) applications are heavily concentrated among a small number of institutions, highlighting the need to broaden the applicant base to encourage more widespread technological innovation. Korea’s fisheries technology sector is currently in the growth stage with sustained development expected in aquaculture and seafood-related technologies. Although Korea entered the IP5 landscape relatively late, it possesses strong competitiveness and considerable development potential positioning it to assume a leading role in the global technology market.

The Internet has opened an industry chain connecting movies, TV, online games and animation, so the IP of online novels is not limited to movie adaptations, but also includes games, anime, and peripheral products. The gradual improvement of the online novel copyright trading market is the transformation of the IP Internet providing a development environment, and building a complete industrial model can make popular IP play a higher value. However, compared with the relatively complete and mature IP industry chain abroad, China's online novel IP industry still has many problems. The problems of the IP industry of online novels have become more and more obvious, and the quality of works is uneven; the main body of each link of the industrial chain is lacking in union; the value of brand IP has not been maximized. The popularity of online novel IP indicates that the industry has recognized the characteristic of "content is king" in the cultural and creative industry, IP development is a long-term process, and it is vigilant that the market caters to the short-sighted behavior of "emphasis on interests and light on culture" This paper discusses the problems of IP development of Internet novel by analyzing the status quo of IP development, analyzing its characteristics and summarizing the mode of IP industrialization of Internet novel from the angle of culture industry development, taking IP as the object of research. Based on the development of the cultural industry value chain, it proposes solutions on how to convert online novel IP into high-quality IP resources and how to develop new models under the original industrial model, with a view to providing a new format for constructing and improving the industrialization of online novel IP reference.
