Research On Patent Portfolio Of VR Enterprises

In recent years,the research and development of virtual reality has been set up around the world,and the application of virtual reality is becoming more and more popular.It has a tendency to replace the traditional information platform such as PC.In this research and development boom,China' s enterprise with developed Internet industry takes the lead in the forefront of the world.However,there is weakness in the patent portfolio of the virtual reality technology in our country,the patent application area is limited,and the industry is limited,and so on.This thesis from the practical point of view,based on the research of worldwide virtual reality patent portfolio,combined with China' s national conditions,analysis of the reasons in the legal and technical level;provide advice to enterprise in virtual reality patent portfolio.The first part describes and analyzes the research background of this thesis,points out that virtual reality technology research will help achieve the corner overtaking in the field of science and technology in our country.The situation of virtual reality patent portfolio research and the research methods used by this thesis are summarized,thus outlined the framework of this thesis from a macro perspective.The second part describes the basic principles of virtual reality and its development history,and points out that virtual reality is not a new technology in recent years,in the last business cycle,the virtual reality has not been given due attention.The characteristics of virtual reality technology are summarized,and through the analysis of virtual reality technology,modular decomposition of virtual reality technology,concludes that virtual reality can be divided into three parts:display technique,data processing technique and 3D modeling technique.This part focuses on finding the corresponding IPC classification group and providing a reliable basis for subsequent patent search.In the third part,I first construct the retrieval equation of virtual reality patent,define the scope of the research,and obtain the accurate patent data.Then analysis the patent filing date,find the pattern of R&D cycle and the characteristics of virtual reality technology development at the present stage.The geographical analysis of said patent data,give us a clear vision of VR patent distribution worldwide and the analysis of patent applicant makes us know the competitive enterprises in the field of VR research.All these analysis is aiming at outlining the target enterprise which is in a leading position of VR field and study the patent portfolio model of said enterprises.This part reaches a conclusion that most of the leading companies in VR field are start-up companies.The fourth part is the analysis of the leading enterprises of virtual reality both home and abroad and gets information of the patent portfolio characteristics of different enterprises.This part finds that the foreign companies focus on the research and development of 3D modeling and date process technique while the domestic companies mostly focus on the Stereoscopic display technique.Most foreign companies build up a patent early warning system while the domestic companies are lack of patent infringement defense measures.To take a closer look at the patent profile details,this part analysis the IPC group of each patent.The R&D focus of each enterprise will be reviewed at the end of this part thus providing data support for patent portfolio strategy.The conclusion part,based on the study of patent portfolio of said enterprises,provide suggestion for patent portfolio from offensive and defensive aspects.Even in the field which virtual reality patent has been widely distributed,there is still a way to break through the monopoly of the patent through cross licensing and thus enter the relevant market.Chinese enterprises need to improve the international awareness of patent portfolio,improve its research and development capabilities,to seize the international market actively.Besides there are other strategies such as constructing the cooperative laboratories in Colleges and universities,and using the preferential policies of various provinces and cities is provided.
