Technological development of smokeless tobacco products status quo and trend
摘要
Abstract
Thomson innovation patent analysis tools were used to investigate smokeless tobacco products between 1985 ~ 2014 to gain an insight into technical features and trend of development of smokeless tobacco products in different countries. Results showed that patent application trend was affected by policy greatly. China and the United States were major applicants for smokeless tobacco technology patent. Transnational tobacco companies have become leading players in the smokeless tobacco product technology research and development through acquisition and merger.关键词
