摘　　要：利用专利情报分析工具Thomoson Innovation,分别通过每年专利申请量、区域分布、专利权人分析了空气净化领域的国际专利基本态势。通过分析得知,空气净化领域的专利申请量从1999年开始出现了迅速的增加,主要分布于美国、日本和中国,主要的专利权人为日本松下(Panasonic)、韩国乐金(LG)、美国唐纳森(Donaldson)公司。通过IPC分类分析了空气净化领域的技术构成,研究发现,空气净化涉及的主要技术领域包括颗粒物的过滤和静电分离、空气的消毒杀菌和空气的调节系统等。同时通过专利主题地形图分析了主要专利权人的技术特点,日本松下和韩国乐金主要集中于室内空气的净化,而美国唐纳森(Donaldson)的技术布局主要涉及工业空气净化。通过专利主题地形图的分析也得知各研究机构及公司在中国的专利布局覆盖了空气净化几乎所有技术领域,而中国的研究机构和公司所拥有的专利相对较少。In this article, the basic trend of patent about air purification was analysed by year amount of patent application, areal distribu-tion and patent assignee using Thomoson Innovation. The analysis showed that application quantity of patent about air purification in-creased rapidly from 1999, and the main applicant countries were America, Japan and China. The primary patent assignees were Panason-ic, LG electronics and Donaldson. Technical constitution of air purification was analysed through International Patent Classification （IPC）. The research found that major technologies in air purification were the filter and electrostatic separation of particulate matter, disin-fection and sterilization of air, and air-conditioning system. The key technology of main patent assignee was also analysed by patent the-mescape. Panasonic and LG focused on indoor air purification, but Donaldson involved industry air purification. The patent themescape al-so showed that patent layout of many research institutions and companies had related to almost all of the technology of air purification, but Chinese research institutions and companies had little patents.
