Patent Knowledge Position And R&D Strategy Of Tech-Innovation Group In Mobile Graphics

Currently, a merging trend among the Mobile net, Internet, Broadcasting are huge impelled by mobile graphics transmitting in the 3rd Generation, which give more support of the high-speed broadband data operation. Therefore, technological evolution of Mobile Graphics and strategies of tech-innovation groups are reviewed by overseas scholars, who attempted to using some methods such as statistics and modeling. Unified with technical information,economical information and commercial information, patent documents are useful to descend knowledge. Knowing about the previous patent analysis research, we choose using scientific metrology and factor analysis methods to analyzing some important enterprises such as Nokia,SamSung,Sony,Matsushita and etc. We could find these significant innovation firms as different roles in a certain technology field. From learning how they got the leaders'positions, we expect to have some suggestions to improve Chinese innovation group in the Mobile Graphics related field.Firstly, we use the patent documents retrieved in the way of combining keywords and IPC from Derwent Innovation Index. There were 3849 patents that all we got. Based on the patent bibliometrics theory, CitesSpace II, an information visualization mechanism, Co-existed analysis and clustering of DMC and Assignees, there are some significant enterprise can be found by their vigorous inventing and their cooperation activities. We can take research on the key techniques, and visualizing their developing innovation pace.Secondly, according to the concept of knowledge position, via qualitative analysis, we can build indexes to measure knowledge potential of each innovation firm(Assignee), such as Nokia,Sunsamg and other 4 enterprises. In Derwernt Manual Codes W01 and T01 technology field, research result shows that Samsung got both of the "leading Innovation" position there; Japanese corporation Sony and Matsushita are "tagging Innovation"; Nokia got the place in the "entering innovation" and have the "tagging Innovation" type in T01.Our Chinese 2 firm Zhongxin and Huawei are still in the "learning Innovation".At last, we can analyze the continuous changing with the Co-existed DMC, which help to explore the Mobile Graphics'technological process history of the significant corporations. During this research, we can shed light on our Chinese innovation group in the Mobile Graphics related field.
