Patent Analysis of Robotic Milking Machine in China
In-depth study of the patent layout of the robotic milking machines in China is of great significance for Chinese technology research and protection.Based on the Derwent Innovation(DI)patent database,using the bibliometric method and topic clustering,the layout characteristics of the robotic milking machine in China are analyzed and summarized from the aspects of annual change of patent application,technology exporting country,patentee,patent legal status,classification defined by experts,IPC classification,research focus,etc.The analysis results showed that China started slowly in this field and entered a period of technological development in 2011.The key patentees of this technology were concentrated,the overall invalid patents accounted for 41%,and the patent maintenance was not strong.Foreign institutions had more effective patent ratios and technical directions in China than domestic institutions.Patent applications by foreign institutions accounted for 22.6%,mainly from Sweden,Germany,Netherlands and the United States,and patentees mainly included DeLaval and GEA.Among domestic institutions,Anhui Yomo Machinery Group Co.and Shandong Chengcheng Iot Technology Co.had more authorized and effective patents.Foreign institutions had more patents than Chinese institutions in advanced technology directions such as automatic teatcup attacher,automatic cluster remover,automatic teat identification equipment,mechanical arm and powerplant of automatic teatcup attacher or remover,automatic attaching or detaching of clusters.It is recommended that Chinese institutions should establish effective cooperation mechanisms such as patent pools,strengthen cooperation between companies,universities,and research institutions,and strengthen the overall patent layout and cutting-edge technology patent layout.
