Abstract:This article is based on the statistical analysis of the data of the "Microorganisms Deposits and Samples (2001-2019)" published by the World Intellectual Property Organization (WIPO). The results show that the global patent microbial deposits have shown a steady growth trend, China ranks first in the world in terms of the number of patent strains, with most of the world's patent strains preserved (31386, accounting for 39.86%). After 2018, the global sample of strains increased sharply, Among which the United States was still the country with the largest number of patent strains (24153 strains, accounting for 96.63% of the total sample), and the sample rate of China's patent strains is at a low level (1034 strains, accounting for 3.29%). The phenomenon of "high preservation, low distribution" of patent strains in China is serious, and the level of industrial development and utilization should be appropriately promoted.
