This article aims to conduct a technology mapping through the monitoring of patent documents by evaluating the evolution of the technologies involved in paints containing biocides in order to provide insight and to strengthen support for making important decisions based on facts and concrete evidence on the dynamics of technological development of paints containing biocides sector. They were initially used data extracted from patent documents on the INPI-BR nationwide database, and the codes of the international patent classification (IPC): subgroup" C09D5/14" and" C09K5/16". There were retrieved a total of 145 patent documents, in general, the main form of deposit used is the internationals deposit (PCT and CUP). As for the countries of origin, we have a concentrated distribution since the first two countries hold 72% of the deposited patent documents; they are United States (40%) and Brazil (32%).
