Abstract

Flexible polyurethane (FPU) foam has recently attained significant attention from various research institutions and industries due to its versatile properties, abundance of raw materials, and renewability. Despite the number of publications of numerous articles, there has been no formal report of its global patent landscape. This study examines the overall patent applications by investigating a dataset of 26,509 patents from 15 countries. The number of patent publication has significantly increase, particularly in the last four years. After constructing a cognitive network, we determine the centrality measures as well as their entropy and diversity. Europe attain both the highest entropy and diversity values which implies that it has the widest information dissemination and uniformity of the distribution of patents. The heat map feature that the most prolific country were USA, China, and Japan. Huge corporations such as Procter & Gamble, 3M Innovative Properties, and Nitto Denko Corporation among others showed huge interest on this particular material.
