The Patent Portfilio Research Of UAV

Unmanned aerial vehicles are divided into military UAV and civilian UAV.In the civilian UAV category,drones have attracted much attention in recent years.Consumer drones formally appeared around 2010,and the degree of attention and sales have gradually reached a peak between two to three years from 2014 to 2016.Although European countries and European countries entered this area earlier,Chinese companies have come from behind,with powerful technologies.Strength and absolute market share gradually emerged in the field of consumer drones and became a leader.As the heat of the market gradually fades,investment decreases,sales decline,and the consumer drones market begins to fluctuate after 2017.Whether Chinese enterprises can occupy the absolute advantage in this field in the future will not only be analyzed from the market,but also We should pay attention to patent analysis and patent layout,and use scientific methods to guide future development.By decomposing technical fields,searching for corresponding keywords,and combining the corresponding IPC classification numbers to construct patent search formulas,a total of 24,327 published patent documents were retrieved on February 1,2018 as time nodes.Patent applications in the field of consumer drones are divided into three phases:the embryonic stage of technology(1999-2008),the technological innovation stage(2008-2013)and the technical explosion stage(after 2013).The number of patent applications has increased exponentially since 2013,with an annual growth rate of more than 100%,but it is predicted that the growth rate of patent applications in this area will slow down after 2017 due to market turmoil.In the field of consumer-grade drones,China's applications account for 37%of the total global applications.Although China's start-up in this area was slightly later than Europe,the number and speed of patent applications in the field in China are far more than the global average.Level and occupy a leading position.Analysis of six major representative competitors of Shenzhen DJI,Parrot,ZEROTECH,YUNEEC,XAIRCRAFT and AEE.The data shows that Shenzhen DJI is not at the consumer level.The number of patent applications in the machine industry ranks first in the world,and its market share is also the highest in the world,far ahead of other competitors.The Parrot company was the first to introduce consumer-grade drones and was the first company to have patents in this area.However,the development in this area was not as good as that of Chinese companies.In this area,companies such as ZEROTECH and YUNEEC continue to follow the pace of the former.However,companies such as XAIRCRAFT and AEE are actively seeking out technologically differentiated developments and strive to open up new ones.The patent application in the field of consumer drones in China has seen a rapid increase in the number of patent applications in a short period of time.It is difficult to form a global situation because of the uneven distribution of geographical distribution.The layout of technical points in this field is not comprehensive enough and the quality of patents varies.And other issues.It is suggested that the patent distribution activities of related companies in consumer-class drones should be carried out according to their own circumstances.They should not blindly pursue the number of applications,but should also focus on improving quality.At the same time,they should consider the future technological development direction of enterprises,build core technology areas,and gradually strengthen Layout to foreign countries.
