Use of Patent Indicators as a Methodology for Evaluating the Development of Supercritical Extraction Technology

The use of science and technology indicators that plan investments in research, development and innovation has been growing in recent years. This article aimed to evaluate the scientific and technological indicators, through research related to patent applications and spending on RD&I carried out by the sponsor countries of supercritical extraction technology. Survey was carried out in the online databases for European office Espacenet (EP), by collecting, processing and analysis of information extracted from patent documents. The researched technology is mainly concentrated in developed countries, which have the largest investments in RD&I in recent years.
