Special yeast, as a kind of biological resource different from traditional yeast, has a wide range of industrial application prospects. By retrieving data from the incoPat database, this article takes the patents of industrial applications of special yeast as the research object. From the perspective of patent analysis, the development trend of technology innovation, technology distribution, main application institutions, research hotspots and application advantages of different kinds of global special yeast industry have been reviewed. Data has shown that the global patent publication amount for special yeast industrial technology presented an increasing trend from 2001 to 2020, and reached a peak in 2019. The patent protection areas concentrated in the US,the P. R. China, South Korea, Japan, Europe and other countries or regions, and the R&D focuses of domestic and foreign applicants differed. Foreign industrial biotechnology companies represented by DSM, Namur DuPont and Novozyme focused on the intellectual property rights of a basic technology of a special yeast. The domestic research institutions represented by Jiangnan University laid more stress on the development of Pichia pastoris technological applications. Finally, the differences in the innovation levels of various kinds of special yeasts from multiple technical branches in recent years have been analyzed, aiming to provide reference for decision-making in scientific research and academic works in the industrial application field of special yeasts in China.
