| Patents are important resource of information. Normally, companies protect their intellectual property right of the core technology of products and research projects via patent application. In view of this, companies can learn the dynamic and key information of some specific fields by studying the patents in these fields, know more about the industrial leaders’ research direction and adjust competitive strategy in time by taking their own comparative advantage into account.This paper studies the patent data of cigarette packaging industry. By leveraging the patent analysis software, it visualizes analysis result. Basing on this, it makes a study on the development trend of cigarette packaging at home and abroad by analyzing cigarette packaging core technology, core enterprises and the development process of industrial chain. From the perspective of technology life cycle, it analyses the development stage of the core technology of cigarette packaging industry and the life cycle of the main technology. It also researches the patent layout of some core enterprises. On the basis of the above mentioned research, it analyses the statistics changes from the perspective of technology and economy, discusses the problems in the packaging industry of cigarette companies and predicts the development trend in this field. On the basis of quantitative analysis and patents text mining, it either sorts out or gather the patents according to the content of patents. It conducts comparative analysis, portfolio analysis and predictive analysis by combing the factors of time and space. On the basis of cross-sectional study, it analyses competitors in the field of core technology by combining the features of strategic decision-making and explores the patent strategy in the field of packaging of cigarette companies in China. |
