Abstract: By using patent information analysis method, the paper investigates the graphane technologyrelated patents, including the time of application, which technology field the patents belong to and distribution of applicants. It finds out that graphane technology patents are widely distributed, but most of them focus on the field of basic applied technology; most applicants are from high-learning schools and research institutions, and cooperation between research teams is seldom seen. Based on the method for calculating the number of patents and the Pearl curve model, it forecasts and analyzes the developing trend of graphane technology. The result shows that graphane technology is at the rapid development stage in China and it will soon enter into the maturation stage. It suggests that China should seize the chance and make new technological breakthroughs.

Key words: patent analysis; graphane; Pearl curve model; developing trend
