Abstract: The preparation,characteristics,development situation of graphene materials were researched.On the basis of the orbit patent database,grapheme patent was qualitatively analyzed,through the patent applications,technology,patent holder,patent map and the patent cited amount.Then,it could reflect the graphene industry trends,technical characteristics,main competitors and the whole patent layout.The combination of qualitative and quantitative data,and combined with graphene industry situation,the current technical difficulties and bottlenecks were analyzed.The suggestions were put forward.
