Characteristics of Global "Marine Aquatic Feed" Domain Development Based on Patent Analysis

[Purpose/Significance] This paper compares the characteristics of "marine aquatic feed" technology evolution in different countries based on the global patent data in order to find out the international situation and problems China is faced with in China's innovation development. [Method/Process] Using bibliometric analysis of patent literature, this paper analyzes the patents development trend, distribution trend, patent competitiveness, patentee's characteristics, and patent technology development of international "marine aquatic feed" field. [Results/Conclusions] The results show that the patented technology of "marine aquatic feed" is being transferred to emerging markets, and refined and breakthrough technology research is the development direction in the future. In recent ten years, China's patents show a strong growth trend, but the development of China's patent portfolio and market inflow in the world is not optimistic. There is a mismatch between the growth of patents quantity and the quality, patent
