钢结构热浸镀技术专利分析

Analysis on Patents of Hot Dip Plating Technology for Steel Structure

热浸镀是目前钢结构腐蚀与防护应用最广泛的技术,通过中国专利数据库、德温特全球专利数据库和欧洲专利局数据库对热浸镀技术相关专利进行检索,并从热浸镀技术专利申请态势、申请区域分布、专利申请人、申请技术分支4个方面对热浸镀技术专利进行分析,指出中国专利申请与其他国家专利申请存在的差距,对热浸镀技术行业发展、专利申请方向提供一定的指导。

Hot dip plating is one of the most widely used technologies for steel structure corrosion protection. Based on the CPRS,WPI DII and the WORDWIDE,the related patents technologies of hot dip plating were retrieved. Hot dip plating patents were analyzed based on four aspects-patent application situation,regional distribution,patent applicants and technology branches. The gaps between China and other countries on patent application were pointed out,which would provide some guidance on the industry development and patent application technique.
