When a company develops a new technology, it should avoid tore of its competitors’ patents. In addition, patent rights can be also as a defensive and assailant weapon in the market. The patent intelligence according to patent analysis reveals the development and tendency of market and technology about competitors and competitive countries. It can make a company understand the conditions and the trend in the market. Patent information is one of the most important reference resources when a company drafts its technology strategy.
As the sense of conserving energy arises in the world, inverters are gradually used in many fields like in industrial motor driving, house electrical appliances, lights, cars, transport etc. Among all applications, the driving of industrial motor can accomplish the action of rationalization, conserving power, conserving energy, conserving space, communication, high function, less noise, low cost etc. At the same time, the market of industrial inverter still reaches 5.6％ growth rate of every year. The paper analyzes patents of industrial inverters by administration and technology dimensions. This research drafts the patent maps using patent analysis and uses the results to make technology strategy. Finally, we propose the conclusions about the industrial inverter and suggestions for the producers.
