Bioethanol is recognized as a potential alternative to petroleum-derived transportation fuels, with several advantages such as high octane number, low cetane number, and high heat of vaporization. The bioethanol production in Brazil uses sugarcane as feedstock and employs first-generation technologies based on the use of the sucrose content of sugarcane. In this sense, the present paper outlines the current bioethanol technology scenario based on the analysis of databases of patent documents filed at the main industrial protection offices. For this purpose, the Lens platform was use to search and analyze patent documents using keywords, according to the search stages. In this sense, the present paper outlines the current scenario of bioethanol technology in the BRICS based on the analysis of databases of patent documents filed at the main industrial protection offices. For this purpose, the Lens platform was use to search and analyze patent documents using keywords, according to the search stages. As a result, 1471 documents ware related to patents and patent applications granted between 1989 and 2019. Regarding the BRICS, China ranks first in the number of registered documents, followed by Brazil and Russia. India and South Africa made no deposits during the study period. From the results, one can observe a trend of growth in the number of patent registrations in Brazil between the years 2016 and 2018, coinciding with the launch of the targets for the "energy" theme of the National Strategy for Science, Technology and Innovation of the Brazilian Government.
