| Taking "Derwent Innovation Index" patent database acquired 6326 International Basketball patent literature(1967-2014 year) for the specific object of study, the use of metering in Patent Document visualization software Citespace its metering software patent literature analysis, reference library and information discipline theory study, the use of literature, patent econometric analysis, mathematical statistics and logical analysis, in the form of visual map showing time, the patent owner, inventor,hot technology in the field of core patents in the field of basketball patents and the distribution system and its analysis.Draw the following conclusions:(1) the number of international basketball patent applications in the years1979-1982 has declined, in 1967-2014 the number of other time basketball patent applications increased. The main distribution of basketball patent subject areas are instruments, sports science, engineering design, chemistry, computer science, polymer science, technology field of material science, communication and construction engineering and the 19 subject areas.(2) The main focus in the US patent holders, some large Japanese companies and some universities in China,Our research focused on basketball patent universities,lack of specialized research institutions, research and development of low quality patents. Inventor mainly in the United States and China, the United States, research and development focused on the structure of the inventor manufacturing and material composition of basketball shoes, basketball training equipment, audio communication equipment basketball game, basketball game sensing equipment, research and development more widely. Chinese people in focused on invention basketball ball,bracket equipment, basketball game lighting, display equipment. R & D China inventor relatively concentrated, is expected in the new field of research and development of basketball patented technology.(3) basketball patent technology hot topics mainly focused on the foam material technology, basketball, basketball, basketball lottery technology liner advertising technology, basketball teaching instrument, floor adjusting device, synthetic rubber,butadiene materials portable auxiliary training equipment and other fields, is mainly reflected in the basketball shoes, polymer materials used, the game of basketball lottery, game advertising field, and basketball teaching instrument and adjusting device manufacturing field. Distribution of the core patents mainly concentrated in the America, design using the technology theme mainly in sport shoes sole cushion and composite rim design and basketball frame connecting device design and electronic game software system field. |
