Abstract:In order to enable domestic researchers and manufacturing enterprises in the field of heated tobacco core materials to avoid intellectual property infringement risks caused by foreign product formulas， preparation processes， product forms， and other product designs and processes. Comprehensive statistics， analysis， sorting， summarization of all patent layouts in China related to the formula design and preparation technology of heated tobacco core materials by four global multinational tobacco companies which were PMI， BAT， JTI， and R.J. Reynolds. The purpose was to provide reference for the innovative breakthrough of design， research and development and production of heated tobacco core materials in China. The results showed that the patent layout of the formula design， preparation process， and product form of heated tobacco core materials by the four major global multinational tobacco companies presented a solid pyramid structure， and the patent layout had the characteristics of rigor， precision， and comprehensiveness.
