In order to reveal the main innovation subjects and technology leaders in the global industry, and provide guidance for China’s industrial policy formulation and enterprise technological innovation strategy, a seven-dimensional patent analysis framework was proposed to analyze the technological development trend of amorphous alloy industry based on the study of patent data. Through patent search and statistical data, the development trend of amorphous alloy patent applications, innovation regions, flow distribution, innovation subjects, innovation categories and innovation hotspots were identified. It is found that the number of patent applications for amorphous alloys has shown a downward trend in recent years, especially in Asia.
