Abstract
Organoids are considered a game-changing paradigm of research models for human physiology and disease, which provides unsurpassed opportunities across disciplines in basic medical research, drug development, and personalized medicine. Here, we made a deep investigation for global patents of organoid technologies in the past decade using bibliometric analysis for the first time. We have identified a total of 672 patents related to organoid technology. The number of annual patent applications exhibits an overall upward growth trend over the past decade, especially entering an exponential growth since 2015. Notably, 76.64% of patents are related to the construction of organoid models. Liver, brain, and intestinal models take up the first three places in the physiological models, while tumor models account for 76.30% of the total patents for disease models. Furthermore, drug screening is the most preferred application, revealing the great commercial value of organoid technologies in precision medicine and preclinical drug screening.
