等离子体空气净化技术的专利申请状况分析

本文对等离子空气净化技术在国内外的专利申请情况进行了统计,分析了该领域申请量的变化规律、申请人的构成以及主要申请人分布,对该领域的发展方向进行了分析和预测。受空气污染的影响,该领域的专利申请量经历了一个迅猛的发展期;国内的申请人的专利申请量以及有效专利持有量均已在世界范围内占据了非常重要的地位,但是仍存在申请质量低、市场转化率低等突出问题;在该领域的未来发展方向中,将等离子技术与吸附、光催化等技术耦合已经成为了国内外关注的重点。

Analysis of Patent Application Situation of Air Purification Technology

This paper makes statistics toward the patent application situation of plasma air purification patent technology at home and abroad,and analyzes the application volume change rule in this field,the structure of applications,and the main applicant distribution,conducts analysis and prediction toward the direction of development in this field. Affected by air pollution, patent application volume in this field has undergone a swift development period; domestic patent application volume an the effective patent holdings occupy a very important positon in the scope of the world,but there still exist the prominent problems such as application quality being low and market conversion rate being low; in the future development direction of the field, coupling the plasma technology with adsorption,photocatalytic technology has become the focus of attention at home and abroad.
