国内加热不燃烧型卷烟专利技术统计分析

Statistical analysis of patents related to heat-not-burn cigarette in China

为使我国烟草行业相关科技人员准确把握加热不燃烧型卷烟研发的技术特点,对国家知识产权局1985—2016年公开公告的有关加热不燃烧型卷烟专利进行了检索和统计分析。结果表明:(1)1985—2016年国家知识产权局共公开972件加热不燃烧型卷烟专利,其中电加热型卷烟专利占75%以上,是目前加热不燃烧型卷烟专利的主流。(2)菲利浦·莫里斯烟草公司在加热不燃烧型卷烟方面申请专利数量最多;国内烟草行业在该领域专利技术研发取得了长足进步,专利总量远超国外烟草公司和其他专利申请人,成为加热不燃烧型卷烟领域专利技术研发的主体。(3)电加热型卷烟专利研发热点和布局重点是加热段结构改进、烟草配方及添加剂优化、加热效果和感官质量提高等方面;燃料加热型卷烟专利研发热点和布局重点是烟草配方及添加剂优化、热源技术和加热段结构改进、感官质量和加热效果提高方面;理化反应加热型卷烟专利研发重点是烟草配方及添加剂优化、加热段结构改进和感官质量提高方面。

In order to accurately understand the scope and technical characteristics of research and development of heat-not-burn cigarettes in China, patents related to heat-not-burn products published by State Intellectual Property Office （SIPO） from 1985 to 2016 were searched and statistically analyzed. The results showed that： 1） During 1985-2016, SIPO published 972 patents related to heat-not-burn products. Among them, the proportion of patents related to electrically headed cigarettes was more than 75%, which was the major technology for heating tobacco. 2） The number of patents related to heat-not-burn products applied by Philip Morris International was the most among foreign applicants. Domestic tobacco industry had made a significant progress in this area, the total amount of patents was more than that of foreign tobacco companies and the other patent applicants. 3） The hot spots of research and development related to electrically heated cigarettes were the modification of heating section, its construction, the optimization of tobacco blending and additives, the improvement of heating effect and sensory quality. For patents related to solid fuel heated cigarettes, the hot spots of research and development were the optimization of tobacco blending and additives, the improvement of heat source technology and heating section construction, and the promotion of sensory quality and heating effect. The hot spots of research and development of patents related to physicochemical reaction heated cigarettes were the optimization of tobacco blending and additives, the modification of heating section construction and the improvement of sensory quality.
