Methods: We will analyze miRNA patents publication year, coun⁃ tries, patent families, assignees, inventors and main manual codes in DII database by using of TDA and Excel. Re⁃ sults: Based on the analysis, we got the structure of miRNA patents publication year, patent families of top 10 countries, top 10 assignees, top 10 inventors and main manual codes in DII database. Conclusion: The results showed that the number of patents on miRNA in China is delightful, however, there are still large distance from USA and so on. Further more, the patent families on miRNA in China were confined in own country without deep⁃ ly extensive distribution in more countries. We should be more active to get informa
