Abstract:To obtain valuable competition and cooperation information through patent analysis is an important means for enterprises to grasp the trend of industrial technology development, to identify competitors and to look for partners. In the case of LED industry, related patents of 26 LED listed companies in China were collected from the Derent database. We explore their partnerships, Technology Association and competing potential through the patent cooperation network, technical network and technology similar analysis. It is found that the LED industry patent with high degree of concentration, but the listed companies lack of technical cooperation; patent mainly concentrated at the rear end of the industrial chain, the front-end core technology needs to be strengthened; the scale of the network technology is growing, and it presents the development trend of multi polarization technology; each of the four competitive areas through similarity analysis has its own advantages, and the potential for win-win cooperation in the future is enormous.
