Patent Management Evaluation of Tobacco Enterprises Based on Grey Relational Analysis and Efficacy Coefficient Method

Abstract

In order to solve the problem of evaluating the patent management level of tobacco enterprises, the paper first constructs the evaluation index system which affects the patent management level, and then uses the Grey Relational Analysis (GRA) method and Efficacy Coefficient Method to model the patent management level and the key factors influencing the evaluation level of a tobacco enterprise in 2009-2018. In the past ten years, the company’s patent management level is on the rise. The results show that the patent management level of the tobacco enterprises in 2017, 2016 and 2013 is the better one, however, the level of patent management declined in 2014. Among them, patent application rate, patent technology value, some invention patent applications, patent market value, patent application cost and number of utility model patent applications has the most important influence on patent management level. The enterprise took the lead in the tobacco industry to centralize intellectual property rights under the management of the company’s Law and Reform Department, and has established a series of management systems. It should rely on the comprehensive talents involved in professional technical, statistical and legal knowledge to fully focus on all aspects of the patent management process, set up a control mechanism, and focus on technological innovation, brand strategy and patents. Form a dynamic analysis and transformation mechanism, strengthen the ability to find innovation and development direction on the shoulder of “patent big data improve the patent management level of enterprises and continuously improve the comprehensive competitiveness of enterprises.
