Abstract

With the rapid increases in patent authorization, massive low quality patents are springing up. The low quality patents have made many troubles to the patent management. It has become an urgent task to construct effective identification method and screen out low quality patents from the massive data. Based on the analysis of patent quality and patent maintenance, an identification method and quantitative index of low quality patents are proposed. By using the inventive patents in the telecommunication field as research samples, the method has been used to identify and analyze low quality patents.

Key words

low quality patent / identification method / patent maintenance / patent quality
