中国爆珠卷烟专利技术研发热点与趋势分析

Analysis of research focus and trend of Chinese patents related to cigarettes with breakable capsules

  • 摘要: 为使科研人员准确把握中国爆珠卷烟专利技术领域的技术研究现状、预测其今后的发展趋势,对1985-2017年国家知识产权局公开公告的339件相关专利进行了统计分析。结果表明:①2010-2017年,爆珠卷烟专利的申请量持续增加,其中发明专利的增速远高于实用新型和外观设计专利。专利指标及技术生命周期图显示该技术正处于快速发展时期,专利数量将继续保持上升态势。②国内烟草行业在该领域的专利申请占总量的59.1%,其中湖北中烟工业有限责任公司的申请量最多。申请量最多的国外烟草公司是菲利普·莫里斯公司。③A24D(胶囊滤嘴的制备)仍将是今后一段时期爆珠卷烟领域的研发热点,C11B(爆珠芯材)、A24F(胶囊滤嘴的结构)、G01N(检测分析方法及设备)和27-99(接装纸等辅材)等小类可能是今后潜在的研发热点。④在胶囊滤嘴外观和胶囊的制备方法方面,应给予适当关注。

     

    Abstract: A total of 339 patents related to cigarettes with breakable capsules were published by the State Intellectual Property Office from 1985 to 2017. These were statistically analyzed to assess the status quo and to forecast development trends. The results showed that:1)The total number of patents related to cigarettes with breakable capsules increased continuously from 2010 to 2017, and the growth rate of invention patents was higher than the other two patent types. The technology for cigarettes with breakable capsules was in the rapid development period and the application number could increase further in the future viewing from both patent index and technology life cycle. 2)The number of patents applied by domestic tobacco industry accounted for 59.1% of the total. Among them, China Tobacco Hubei Industrial Limited Corporation possessed the largest number of application. However, the amount of patents applied by Philip Morris International Inc. was the highest in foreign applicants. 3)A24D technology would still be the hot research topics in the coming period. C11B, A24F, G01N, and 27-99 subclasses might be the potential research focus. 4)Adequate attention should be paid to the fields of appearance of capsule filters and capsule preparation methods.
