The present study intends to present the relevance of cellulose by means of the technological foresight study through citing and cited documents from a patent application (WO 9745131 A1) as indicators of innovation. The European database of patents (espacenet) was used, combining keywords and IPC. The major applicants, countries of publication and uses were mapped. The patent requests collected are mainly distributed in the area of polymers to medical devices and therapeutic methods that utilize cellulose. The results obtained revealed that the US were the main country with studies directed to this technological area (18 patent applications) and the major applicant was the company Micro Therapeutics Inc. Therefore, we can understand that this is a promising technology that may reflect in an increase of R&D activities and in the patent deposits in this area.Downloads
