Abstract:

 Based on statistical analysis and visualization method,the cell therapy patents from 2006 to 2016 collected by the Derwent Innovation Index databases are analyzed,analyzing such as patent trend,category,proprietor,inventor network,hot sports,Derwent Manual Code and high cited patents. The results show: 1) Cell therapy technology presents a wave like rise and the technology involves highly concentrated category; 2) Developed countries lead the technical development direction, but the technical cooperation between inventor is low; 3) Hot spots mainly concentrate on the source of cell,cell culture, antigen antibody preparation,induction materials,process,anti-inflammatory and anti infection and so on. 4) From the time evolution,the cell source and cell culture is a constant theme. With the development of technology,process optimization,the diversification of treatment programs are gradually emerging as a new focus. Based on the practical situation of the development of cell therapy technology in China,the suggestion is proposed.

Key words: cell therapy, patent analysis, technology evolution, hot spots
