A note on growth of superconductivity patents with two new indicators

Patent statistics may be indicative of growth and evolution of technologies in relation to a scientific field or sub-field of research. In this paper annual growth of patents in the field of superconductivity has been studied. The data in five-yearly cumulation have been set against research papers on superconductivity to show comparative growth of basic research and technological development. Two simple indicators have been devised to understand the apparent influence of basic research on technology and trends of relative growth.
