The earliest patent application for UAV in China was 1986. It is an electronic digital altitude display device for UAV altitude control submitted by the Third Research Institute of the Second Artillery Corps of the Chinese People's Liberation Army. In 2 1 century, the number of patent applications for UAVs increased year by year, reaching more than 2,000 in 20 15, reflecting the rapid development and technical research of UAV industry in recent years.
Prospective Industry Research Institute believes that UAV products involve many fields such as machinery, electronic control, agriculture, environmental protection and electric power. Through the analysis of the technical topics of relevant patent documents, the technical hotspots about UAV mainly focus on the operation and control, flight equipment and fuselage structure of UAV, and the two-wing or multi-wing rotorcraft is the main way of UAV products. UAV-related inventions are shifting from infrastructure components to UAV application systems, which is also a problem worthy of attention and consideration in the patent application and layout of UAV industry.
Developed countries in Europe and America and China are the most important areas for UAV patent application. Although the number of patentees from China is far less than that of developed countries in Europe and America, China has become the first country to apply for a patent for UAV technology because of China's vast market space and the development trend that cannot be ignored, as well as the China government's vigorous promotion of intellectual property protection in recent years.
At present, UAVs in China are mainly concentrated in the field of civilian consumption. Although the number of patent applications for unmanned aerial vehicles has increased rapidly, the number of applicants has also increased rapidly, and the application and technical fields have expanded rapidly, on the whole, research is still the mainstay, lacking core patents, and there is still a certain gap between key technologies and foreign countries. However, domestic large-scale patent application and layout have not yet started abroad. Relevant enterprises in China should seize the opportunity to further strengthen patent application, layout and application, actively seek foreign patent application and layout, and expand their own markets.
