This article refers to the study of monitoring of technological generation in the development of process using sleep chemistry, from the research of information in the main patent banks, such as the European Patent Office (EPO), the US Patent and Trademark Office (USPTO), the Brazilian National Institute of Industrial Property (INPI), among others. To obtain the information, the Questel Orbit® platform was-used, applying as input the keywords for the searches "sonochemical", "ultrasound", "membranes", “polymer”. We performed "macro", "meso" and "micro" analyzes, with the objective of raising the main technological characteristics related to the process using sleep ultrasound over the last years. Among the areas of ultrasound-related technologies, Chemical Engineering was the most prominent in the preparation and use of ultrasound in polymer membranes, accounting for 19% of the total. The main raw material used for the production / application together with the ultrasound was the polymer polyetherimide, also prominent for cellulose.
