中国矿用风机产业技术竞争态势研究——基于专利的视角

A Study on the Technological Competition Situation of Mine Ventilator in China under the Perspective of Patent Analysis

简要地概述了中国矿用风机市场需求的发展现状,对中国矿用风机专利保护现有研究进行综述分析。在构建检索表达式的基础上,利用上海知识产权(专利信息)公共服务平台对中国矿用风机专利信息进行全面检索,形成数据库,借助产业技术竞争情报的理论和方法,从年度申请量、申请人、发明人、专利分类号(IPC)、技术功效、专利区域分布和生命周期等角度对中国矿用风机产业的技术发展历程、技术竞争主体、技术竞争领域和技术竞争环境等4个方面进行实证分析,最终为中国矿用风机的技术创新和专利布局提出发展建议。

The development status quo of the mine ventilator technology in China was briefly introduced, the previous researches of its pa-tent protection were summarized, and the patent information was collected from the Shanghai Intellectual Property information platform based on the construction of patent retrieving expressions. Based on the theories and methods of industrial technological competition intelli-gence, an empirical investigation about the technological development course, competitive parties, competitive fields, and competitive en-vironment of mine ventilator in China was then conducted from the perspectives of annual trend, applicants, inventors, patent IPC, tech-nology-effect matrix, patent distribution of regions, patent life-cycle and so on. Suggestions on the development of the technological in-novation and patent layout of mine ventilator in China were given at last.
