Visualization analysis of vinegar patents based on patent literature

Vinegar is one of the most widely used sour condiments in the world. With the deepening of vinegar research, the scientific and technological innovations in vinegar industry are constantly strengthened. Based on patent literature and driven by data thinking, the visualization of inactive vinegar patents was performed by using PatSnap. Macroscopically, the patent types, application trends and technology life cycle as well as top assignees and geographic distribution of patents in the vinegar field were analyzed and compared. Microcosmically, the key invention and utility model patents were identified through patent citation analysis. Besides, combined with international patent classification, patent keywords cloud and 3D patent map, the technical themes of invention and utility model patents were distinguished. In this study, patents in the vinegar field were dissected from the perspective of patent visualization. This study will help to provide a sketch to reflect the status, progress, hot spots and trends of technological innovations in vinegar industry, and to provide reference for related research in vinegar field.
