Research On Patent Development Strategy Of Technology Standard Alliance Of Hi-tech Enterprises

From the view of strategy management, through technolgy standalization strategy theory, technolgy compatible theory, game theory and real option evluation theory, this dissertation analyzed the operation law of technology standard alliance of high-tech enterprise, and researched the patent development strategy of choice mechanism, evaluation mechanism and control mechanism to promote the formation and bettering of research platform of technology standard alliance of high-tech enterprise and its patent development strategy.As for the the operation law of technology standard alliance of high-tech enterprise, this dissertation researched the formation background, formation forces and evolution trends, and analyzed the relation characteristic between dominant patent and subservien patent, core patent and peripheral patent, technology standard and technology patent. The research shows that the basic strategy of technology standard alliance is a long plan with cooperative R&D, technolgy patent strategy and technolgy standard cooperation.As for the choice of patent development strategy of technology standard alliance of high-tech enterprise , this dissertation constructed adverse selection model and patent development competition model, and analyzed the game process of alliance constrution decision. Through analyzing the Cournot equilibrium and Bertrand equilibrium, this dissertation explored the alliance constrution and the effect of adopting different technolgy stardards on the enterprise profit and society welfare. Introducing deviation degree and risk factor, the model of single patent choice was constructed. By deviding technolgy standard into many dependent complete modules, this dissertation constructed many patents choice model, which could provide a basic ways to choose a property technolgy patent for every dependent module. As for the complex relation among the patents in the technolgy standards, this dissertation construted the choice model of compound patents, which provieded a decision basis for alliance.As for the evaluation of patent development strategy of technology standard alliance of high-tech enterprises, through compared the return change of technology standard alliance, this dissertation summarized the reasons that alliance had a enough return. Through construting the two return evaluation model of developing patent independently and cooperatively, this dissertation analyzed the return difference of patent development patterns for the alliance enperises. From the view of investment-return evluation, this dissertation classified the technolgy patents into essential patents and peripheral patents, and constructed real option evaluation model of multi-patent development. After dominant patent development, subservien patents must be developed. Therefore, regarding the subservien patent development as the embedded option of dominant patent development option, through constructing real option evaluation model of compound patent development, this dissertation analyzed the cost economic value and demand pull value of subservien patent.As for the control of patent development strategy of technology standard alliance of high-tech enterprise , classfying the patent share control patterns into one-side control, multi-sides control and sharing control, through constructing the patent share game model of alliance, this dissertation explored the effect of patent share control pattern on the level of knowledge disclose and R&D effort. As for the different control of multi-patent of alliance, through constructing the different game model of patent, this dissertation explored the the basic strategy of patent cross-licensing of alliance enterprises and different control in the different network externality. Introducing three stage dynamic game model, through analyzing the game path of technolgy standard compatibility, this dissertation provided the basic compatibility control strategy in the condition of disadvantaged competition enterprise combined. Competition enterprise could develop some peripheral patents on the basis of the technology patent the alliance owned, which could realize the same or familiar funtion with alliance patents. And then the competition enterprise could combined other disadvantaged enterprises to implement technology standard compatibility strategy. As for the above competition threat, this dissertation provided a basic control strategy of patent licensing from the view of per-unit cost and technolgy content.As for the empirical study, this dissertation testified the scientific and applicability of patent development strategy choice, evaluation and control. Meanwhile, through the case study of AVS alliance, MPEG-2 alliance, 3G alliance and GSM alliance, this dissertation revealed the patent development strategy of technolgy standard alliance of high-tech enterprises and testified the topic and main conclusions.
