| Abstract: | The patent database of China Association for Science and Technology （CAST） was sur- veyed for US electrical technology patents, the application of which were filed between 1998 and 2012. Patent indicators of electrical technology in the primary and secondary technical fields of elec- trical technology and the distribution of electrical technology in the international patent classification （IPC） were adopted to analyse the trends of electrical technology development in the United States. The results indicate that the development of electrical technology in the U. S. is closely associated with the economic environment and innovations, that the US patent applications of electrical technology focus on the smart grid and are mainly distributed in the motor and electric appliance technology, communication technology and information technology. |
