無人機產業在近幾年的發展速度非常快，市場研究公司Gartner表示：2016年全球無人機銷量攀升至220萬台，收入同比激增36%，達到45億美元；有專家預計2021年的無人機銷售額將超過120億美元。這意謂著複合年增長率(CAGR)將由2016年的85億美元上升7.6%，在無人機市場被一路看好之下，無人機的相關運用也逐漸在工、商業領域中大量運用。
雖然市場正熱，不過其實目前無人機有諸多技術正處於瓶頸且無法突破，無人機的續航力便是其中之一。據研究顯示市面上有50%的無人機的電池續航力不足以支撐30分鐘的飛行，這對於日後無人機的應用有諸多的限制，特別是在工、商業用的無人機需要執行特殊、重要的任務。
因此本研究有鑑於目前無人機的續航力技術狀況，以專利觀點分析現階段所提出的各種技術，希望能釐清各種技術的進展狀況以及專利申請人的市場分佈，給未來想要進入無人機產業的廠商有一定量的資訊做出正確的選擇。

Unmanned aerial vehicle’s industry grows very fast. Based on market research company, Gartner, it shows that drone’s sale would be up to 220 million units and revenue could be up to 4.5 billion dollars. Unmanned aerial vehicle’s industry has a prosperous future, so there are more and more applications in commercial and industrial fields.
Although drone’s market is very hot, there are still many technological problems which need to be solved. One of important problems is the limited time of flight. Based on report, nearly 50% of drones can’t fly over 30 minutes. It’s a serious limitation for drone to apply in commercial and industrial fields, due to bad battery duration.
As a result, this paper want to use the prospect of patent analysis to analyze different technologies which can raise the time of flight and patent assignees. It will provide some helpful information for someone who wants to enter the Unmanned aerial vehicle’s industry.
