Resumo: Desalination consists of removing salts from brackish water or seawater. Among the various known water desalination methods, the main ones are thermal and membrane, where reverse osmosis is the most common, and by electrodialysis. Water desalination is an alternative to the water supply that intends to meet the demands for drinking water. The aim of this study was to carry out a technological prospecting for patents related to water desalination. The following online patent databases were consulted: National Institute of Industrial Property (INPI), World Intellectual Property Organization (WIPO) and European Patent Office (EPO) using various descriptor terms. With the results obtained, surveys were made chronological period of filing, distribution of patents by countries and classification of patents according to the International Patent Classification (IPC). It was found that the WIPO database had the largest number of filed patents (208,425), followed by EPO (190,906) and INPI (118). According to IPC, most patents had these classifications: 52.91% include section C (Chemistry; Metallurgy), followed by section B (Performing operations; Transporting) with 39.84%. The largest number of patents occurred in 2019, with 3,026 filings, with the United States of America and China holding the largest number of registered patents. Faced with the scenario of world population growth and climate change, the promotion of new technologies that recycle water presents a promising alternative.

Dentre os vários métodos de dessalinização de água conhecidos, os principais são o térmico e de membranas, onde a osmose reversa é a mais comum, e por eletrodiálise. A dessalinização da água é uma alternativa de aporte hídrico que visa atender as demandas por água potável. O objetivo desse estudo foi realizar uma prospecção tecnológica de patentes relacionadas à dessalinização de água. Foram consultados os seguintes bancos de dados on-line de patentes: Instituto Nacional da Propriedade Industrial (INPI), World Intellectual Property Organization (WIPO) e European Patent Office (EPO) usando diversos termos descritores. Com os resultados obtidos foram feitos levantamentos cronológicos de depósito, distribuição das patentes por países e classificação das patentes de acordo com a Classificação Internacional de Patente (CIP). Verificou-se que o banco de dados da WIPO apresentou o maior número de depósitos (208.425), seguido pelo EPO (190.906) e INPI (118). De acordo com a CIP, a maioria das patentes apresentaram estas classificações: 52,91% contemplam a seção C (Química; Metalúrgica), seguida pela seção B (Operações de procedimentos; Transporte) com 39,84%. O maior número de patentes ocorreu em 2019, com 3.026 depósitos, sendo que os Estados Unidos da América e a China detêm o maior número de patentes registradas. Frente ao cenário de crescimento populacional mundial e às mudanças climáticas, a promoção de novas tecnologias que reciclem a água apresenta uma alternativa promissora.Revista Brasileira Multidisciplinar - ReBraM2022-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistarebram.com/index.php/revistauniara/article/view/123510.25061/2527-2675/ReBraM/2022.v25i3.1235Revista Brasileira Multidisciplinar; v. 25 n. 3 (2022): Setembro-Dezembro; 48-612527-26751415-3580reponame:Revista Brasileira Multidisciplinarinstname:Universidade de Araraquara (UNIARA)instacron:UNIARAporhttp://revistarebram.com/index.php/revistauniara/article/view/1235/855Copyright (c) 2023 Revista Brasileira Multidisciplinar - ReBraMhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGomes, Augusto César CavalcantiSá, Emilly Andrade deSilva, Jéssica Laís Bezerra daDiniz, Michely Correia2023-03-23T23:25:54Zoai:ojs.revistarebram.com:article/1235Revistahttp://revistarebram.com/index.php/revistauniaraPRIhttps://revistarebram.com/index.php/revistauniara/oairevistauniara@uniara.com||2527-26752527-2675opendoar:2023-03-23T23:25:54Revista Brasileira Multidisciplinar - Universidade de Araraquara (UNIARA)false
