油气管道防腐蚀专利技术图

Map of Patent Corrosion Control Technologies of Oil Pipelines in China

专利管理的重要任务之一就是专利检索。专利检索之后,可以制作专利地图,以便直观方便的利用专利资料,进行专利信息库建设。文章以"油气管道防腐蚀技术"作为研究对象,通过检索油气管道防腐蚀技术领域申请的专利,制作成专利技术图。对油气管道防腐蚀领域的专利申请趋势、主要竞争对手、国际专利分类、技术类别以及失效专利等进行了分析,可以为油气管道生产企业提供参考。

Patent retrieval is one of important tasks in patent management. After patent retrieval, patent map can be produced so that patent information can be utilized conveniently and patent database can also be established. In a ease study of ＂Corrosion Prevention Technology of Oil ＆ Gas Pipelines＂ , patent technology map has been produced by searching patents in the field of corrosion control for oil ＆ gas pipelines. The invention patent application trend, main competitors, IPC, technical classification and invalidated patent, etc are analyzed, providing a good referenee for the operation companies of the oil ＆ gas pipeline.
