Analysis of Euphausia superba Industry Patent Technology Status in China

The paper aims to discuss the current status and existing problems of patent technology development of Euphausia superba industry in China. Using bibliometrics and text mining methods, this paper analyzed E. superba patent applications in China, including overview, application trends and technology life cycle, patent space and technology distributions, applicants and patent value analysis. The results show that the research and development of China’s E. superba patent technology is in the development stage, and the level of patent technology has been improved. However, the value of E. superba patents owned by foreign applicants is high. Attention should be paid to improving the quality of China’s E. superba patents, and carrying out research on E. superba industry planning and strategy, so as to provide reference for the development of the entire industrial chain of E. superba in China.
