GAN Shaoning, deputy director of State Intellectual Property Office, said that there is still a large gap between the levels of domestic and foreign patents, such as invention patents in respect of the protection scope and technical complexity.

In addition, the invention patent applications and authorizations continue to show the relatively gathering momentum and uneven development in different regions. In 2011, the eastern coastal economically developed areas occupy about 65% of the national invention patent applications and authorizations.

The data also shows that China continues to maintain a competitive edge in the field of traditional technologies, but key technical fields yet to break through.
