Abstract
This paper suggests a method for Subject–Action–Object SAO network analysis of patents for technology trends identification by using the concept of function The proposed method solves the shortcoming of the keywordbased approach to identification of technology trends ie that it cannot represent how technologies are used or for what purpose The concept of function provides information on how a technology is used and how it interacts with other technologies the keywordbased approach does not provide such information The proposed method uses an SAO model and represents “key concept” instead of “key word” We present a procedure that formulates an SAO network by using SAO models extracted from patent documents and a method that applies actor network theory to analyze technology implications of the SAO network To demonstrate the effectiveness of the SAO network this paper presents a case study of patents related to Polymer Electrolyte Membrane technology in Proton Exchange Membrane Fuel Cells
