Based on the analysis of Sichuan liquor invention patent application trend, distribution of patent application types, patent grant rate and patent regional distribution from 2010 to 2024, it is found that Sichuan liquor industry has some problems, such as low patent application quality, low invention patent grant rate, insufficient patent application motivation and lack of reasonable patent strategy layout.In order to improve the patent licensing rate and innovation ability of Sichuan liquor industry and promote its sustainable development, it is suggested Sichuan liquor enterprises choose high-quality agencies to improve the patent authorization rate, pay attention to the quality of application documents and the quality of reply to the review opinions, improve the enterprise's attention to patents and application awareness, and flexibly formulate patent strategic layout according to the changes in the product market.
