Paper Abstract

Prospective studies are based on the analysis of patent documents and aims to assess the both technological history and development providing innovation opportunities. This study was a technological prospection mapping aiming to identify breakthrough in PDT and the new possibilities of the technology. Therefore, research in the bank patent 'Spacenet Patent Search' was performed using determinants descriptors associated with the theme: 'A61K41', 'A61N5 / 06'. Were analyzed in this study 326 documents. In evaluating these patents, it was possible to observe an increase in the number of deposits over time, with peak between 1990 and 2000. The highest number of inventors of this area are part of the private sector and the US appear as main producer of technology. It was also observed that blue light, porphyrins and their derivatives are the main topics. It may be concluded that PDT still offers a large opportunity for growth as several wavelengths, and photosensitizers that may be used in the technique.
