摘要 在新型冠状病毒肺炎疫情爆发以来,口罩发挥了至关重要的作用,聚丙烯熔喷布作为口罩的核心材料,直接决定口罩的呼吸防护性能。因此,有必要对聚丙烯熔喷布产业技术竞争态势进行研究,并为国内技术创新提供信息情报支撑和指导性建议。本文利用向量空间模型理论在国家知识产权局专利检索与服务系统获取专利文献数据,利用Patsnap、Patentics专利检索平台获取专利申请法律状态数据,从全球机构技术产出趋势、全球机构技术领域、全球机构技术流向、全球机构竞争主体力量、热点技术演进和在华布局、国内企业被诉侵权的典型案例角度进行了专利分析。本文为我国企业参与国际竞争市场提出两点建议:注重产学研合作并充分利用国外申请人已失效的专利技术、注意规避国外企业在华专利的知识产权风险。

Abstract: Since the outbreak of the COVID-19, masks have played a vital role. As the core material of masks, polypropylene meltblown cloth directly determines the respiratory protection performance of masks. Therefore, it is necessary to study the technological competition situation of the polypropylene meltblown cloth industry, and provide information support and guiding suggestions for domestic technological innovation. Use vector space model theory to obtain patent document data in patent search and service system of the patent Office, use Patsnap, Patentics patent search platform to obtain patent application legal status data, from global institutional technology output trends, global institutional technology fields, global institutional technology flow, global institutional competition patent analysis is carried out from the perspective of main force, hot technology evolution and deployment in China, and typical cases of domestic enterprises being sued for infringement. Based on this, the thesis puts forward two suggestions for Chinese enterprises to participate in the international competitive market: focus on industry-university-research cooperation and make full use of the expired patent technology of foreign applicants, and pay attention to avoiding the intellectual property risks of foreign enterprises' patents in China.
