Abstract：[Purposes] Agarose oligosaccharides have broad application prospects in many fields such as medicine，food，and cosmetics.This study aims to analyze the evolution of agarose oligosaccharides application technology globally and in China from the patent perspective，providing references for decisionmaking.[Methods] This article conducts a patent analysis on the application of agarose oligosaccharides through the incoPat global patent database，including patent application trends， patent technology composition，global and domestic distribution，and analysis of major applicants.[Findings] The results show that the main applicant countries for agarose oligosaccharides application technology patents are China， Korea，and Japan. Domestic patent applications in China are mainly concentrated in provinces such as Fujian，Zhejiang，and Shandong，distributed in industrial fields such asmedicine，food，and cosmetics; Globally and in China，there is a large number of patent applications for agarose oligosaccharides application technology in the fields of medicine，cosmetics，and food.The main types of Chinese applicants are universities and research institutes; China has a significant advantage in terms of patent application volume，but the proportion of valid patents in the pharmaceutical and cosmetics fields is lower than the global average.[Conclusion] Although China has a significant advantage in patent application volume， thequality of patents needs to be improved.It is necessary to strengthen research and development of patent technologies in related fields，encourage enterprises to carry out reasonable patent layout，and further improve patent quality.
