摘要
为全面了解"十二五"期间我国烟用添加剂技术领域的发展现状,预测今后的发展趋势,对2011—2015年国家知识产权局公开公告的1 666件相关专利进行了统计分析。结果表明:(1)2011—2015年,烟用添加剂专利申请总量持续提升,尤其是发明专利,其中湖北中烟和云南中烟的申请量最多。(2)A24B、C11B以及A24D类技术仍将是今后一段时间内技术研发的热点区域,C08B、B01J、C12P、B01D、C07H以及D21H类技术可能是今后潜在的研发热点。(3)国外申请人在华专利布局以英美烟草、雷诺烟草、日本烟草和菲莫烟草的申请量最多,其中英美烟草的技术布局区域最广。
Total of 1 666 patents related to tobacco additives published by State Intellectual Property Office during 2011 to 2015 were statistically analyzed for fully understanding the status quo and forecasting the development trends of tobacco additives. The results showed that： 1） The total number of tobacco additive patent applications raised continuously from 2011 to 2015, especially the number of invention patents. Among them, the numbers of patents applied by China Tobacco Hubei Industrial Limited Company and China Tobacco Yunnan Industrial Limited Company were the most. 2） A24B, CIIB and A24D patents would still be the research focus of tobacco additives, C08B, B01J, C12P, B01D, C07H and D21H might be the potential hot topics in the future. 3） Among the foreign applicants, the numbers of tobacco additive patents owned by British American Tobacco Company, R J Reynolds Tobacco Company, Japan Tobacco Company and Philip Morris Tobacco Company were the most, especially British American Tobacco Company.
