To help the scientific and technical personnel in tobacco industry better grasp the technical characteristics of heating type smokeless tobacco product,the relevant patents published by State Intellectual Property Office (SIPO)and European Patent Office (EPO)from 2001 to 2012 were statistically analyzed.The results showed that:1) 264 patents in heating type smokeless tobacco products were published by SIPO from 2001 to 2012,including 251 electric heating type patents,8 fuel heating type patents,and 5 physicochemical reaction heating type patents.2) 254 patents in heating type smokeless tobacco products were published by EPO from 2001 to 2012,including 192 electric heating type patents,45 fuel heating type patents,and 17 physicochemical reaction heating type patents.3)27 patents published by SIPO were applied by foreign enterprises,including 24 invention patents,12 of them were applied by Philip Morris Products SA and 5 patents were applied by Japan Tobacco Inc.4) 4 patents were applied by domestic tobacco enterprises in recent 10 years,and all of them were practical new type patents.It meant that the patents in heating type smokeless tobacco products were predominantly owned by foreign tobacco enterprises,especially in the electric heating type containing visible tobacco material.The patents in heating type smokeless tobacco products owned by China tobacco industry were much less,therefore the research and development of heating type smokeless tobacco products should be strengthened in China tobacco industry.%为使我国烟草行业相关科研技术人员准确把握加热型无烟气烟草制品研发的技术特点,对2001～2012年国家知识产权局和欧洲专利局世界专利数据库有关加热型无烟气烟草制品专利进行了检索、统计和分析.结果表明:①2001～2012年国家知识产权局共公开264件加热型无烟气烟草制品专利.其中,电加热型专利251件,燃料加热型专利8件,理化反应加热型专利5件;②2001～2012年欧洲专利局世界专利数据库中有加热型无烟气烟草制品专利254件.其中,电加热型专利192件,燃料加热型专利45件,理化反应加热型专利17件;③国外企业在我国申请的加热型无烟气烟草制品专利有27件,其中发明专利24件,菲·莫公司12件,日本烟草公司5件;④近10年间我国烟草行业申请4件加热型无烟气烟草制品方面的专利,而且都是实用新型.国外烟草企业在加热型无烟气烟草制品领域的专利拥有量占优势,尤其是在含有可见的烟草物质的电加热型卷烟领域,在我国已初步形成了较为严密的专利布局,而我国烟草行业在加热型无烟气烟草制品的专利明显处于弱势地位,在该领域的研发力度有待加强.
