基于专利信息的全球固体香料滤棒技术分析

Global Solid Flavor Filter Rod Technology Analysis Based on Patent Information

本文分析国内外固体香料滤棒技术相关专利申请现状和技术布局及研发热点,对818件国内外固体香料滤棒相关专利进行定性和定量分析。结果表明:(1)国内外固体香料滤棒专利数量一致处于波动增长的趋势;从专利保护国和地区分布对比来看,中国的专利申请量达到286件,占全球专利总量的三分之一,并且是排名第二的美国专利申请量的两倍;全球固体香料滤棒技术专利申请主体集中,技术均掌握在几大烟草公司的手中。(2)国内固体香料滤棒专利出现较晚,但已成为固态香料滤棒领域的主要市场主体,近几年国外申请人则放慢在中国市场的专利布局;从技术层面看,国人多注重通过合成固体香料和活性炭吸附来改善卷烟的香味,固体香料多添加在滤棒纤维或滤棒的独立元件中;从技术空白点看,国人在减少香气损失方面研究较少。

This article analyzes the status quo of patent application and technology layout and research hotspots of solid flavor filter rod technology at home and abroad,and conducts qualitative and quantitative analysis of 818 global solid perfume filter rod related patents.The results show that:(1)the number of patents for solid flavor filter rods at home and abroad is in a trend of fluctuating growth;from the comparison of the distribution of patent protection countries and regions,China's patent applications have reached 286,accounting for one-third of the total global patents,and is twice the number of the secondranked US patent applications;global solid flavor filter rod technology patent applications are concentrated in the main body,and the technology is in the hands of several major tobacco companies.(2)Domestic solid flavor filter rod patents appeared later,but has become the main market;in recent years,foreign applicants have slowed down the patent layout in the Chinese market;from a technical perspective,Chinese people pay more attention to improve the aroma of cigarettes through the synthesis of solid spices and activated carbon adsorption,solid spices are often added to the filter rod fibers or separate components of the filter rod;from the technical blank point of view,there are few studies on reducing aroma loss in China.Chinese applicants pay more attention to solid branch preparation method technology branch.
