Patent Navigation Research on New Display and Strategic Electronic Materials in China—Taking Key Technologies in the Field of E-Paper as an Example
As one of the core contents of"New Display and Strategic Electronic Materials",a key project in the"14th Five-Year Plan",coupled with the vigorous development of smart logistics and other related fields,e-paper has ushered in new development opportunities.Based on patent analysis,this article explores in-depth the domestic and international development status,innovation team patent distribution,and research hotspots of its key technologies,providing referential suggestions for the research and patent application.From the perspective of publication countries/areas,in the early days,Japan had the largest number of annual invention applications,but since the"13th Five-Year Plan",the proportion of China has reached the highest;in terms of the applicant countries/areas analysis of high-value patents,there is no similar advantage in China;the invention patents for"improving display quality"have higher percentage of the granted ones and better performance in the patent strength,but due to the market demand,those for"improving reliability"account for larger proportion of annual applications.Although China has certain advantages in the field of e-paper,it is still insufficient in high-value patents.Thus,while paying attention to the market demand,China should focus on the technological gaps,as well as the research of core patents and key technologies.
