Research On Patent Strategy Of Communication Enterprises Based On Patent Value Chain

As the development of knowledge economy,patents are increasingly important to enterprises,especially new high-tech enterprises.In recent years,Chinese enterprises have narrowed the gap with developed countries in patent application.But some problems still exist,such as the awareness of patent portfolio is weak,the level of innovation and patents' practical application is low.Thus enterprises need to formulate effective patent strategy to promote the overall level of enterprise patent.The telecommunication industry is a typical patent intensive industry.The research of communication patent has its own features such as high cost,high risk,long researching period,thus it needs strategic management of patents.Therefore,with telecommunication industry as t he example,the research on patent strategy of enterprises is of great practical significance.This paper constructs patent strategy frame model on basis of patent value chain theory and incorporates patent exploitation,patent management,patent portfolio,patent indemnification and patent operation into patent strategy frame.It extends the traditional researches of patent strategy.According to literatures and enterprise practice,the paper builds the relevant indicator system of patent strategy and iden tifies the type of enterprise patent strategy with clustering and factor analysis.In the meantime,the paper takes empirical approach to analyze influence factors of the type of enterprise patent strategy and offers proposals to different types of enterpr ise patent strategy on basis of this.The paper mainly has the following research conclusions: First,currently Chinese telecommunication industry has four types of patent strategy: comprehensive type,exploitative type,defensive type and marginal type.Second,there are significant differences among different types of patent strategy: all kinds of patent activities of enterprises with comprehensive strategy are at the leading level;enterprises with exploitative strategy rank only second to enterprises with well-rounded strategy on patent exploitation,patent management,patent portfolio,patent indemnification and patent operation and their level of patents' practical application is outstanding;enterprises with defensive strategy attach importance to pa tent indemnification despite the their general level is low;the level of all patent activities across the value chain of enterprises with margina l strategy is lower than other types of enterprises.Third,the paper finds that enterprise patent strategy is closely associated with its characteristics through crosstable analysis and logistic regression analysis.In perspective of enterprise nature,activities of private enterprise patents still lag behind;the patent classification of collective enterprises and enterprises from Hong Kong,Macao and Taiwan is not obvious due to their small number and most foreign-owned enterprises are in status of defense.In perspective of enterprise scale,enterprise scale measured by the number of enterprise's research and development scholars,enterprise's research and development investment or the enterprise's main revenue all show a positive correlation with enterprise patent strategy.On purpose of enterprise application,most enterprises tend to use patents to grab market share.The enterprise patent strategy analysis framework based on the patent value chain can accurately identify the enterprise patent strategy type,and then provide suggestions and countermeasures to improve the patent strategy.
