Patent competition and value for wireless technologies: in case of intelligent media

Abstract

This study employs the International Patent Classification (IPC) codes, along with advanced data clustering techniques such as K-means, to analyze the development trends, key technological areas, and patent value of Intelligent Media (IM) technology. By applying K-means clustering to the patent data, distinct clusters and trends within the IM technology field are identified. The analysis of IPC codes reveals the evolution of technological areas and their corresponding patent valuation. The study uncovers that the nascent stage of IM technology (IPC codes: H04B, H04N) focuses on multi-channel transmission, encoding signal devices, and electronic communication technology. In the rapid development stage (IPC codes: H04L, H04W, H04N), technologies such as color image component pulse code modulation, wireless radio circuit signal devices, and television cameras thrive. In the stable development stage (IPC codes: H04M, H04B, H04W), cordless telephones, vehicle communication, electromagnetic radiation sensing, and electronic communication technology switching are the main areas of interest. Additionally, the study reveals the international competitive landscape in the IM technology domain, highlighting China and the United States as the main competing countries, with Huawei and Apple as the primary competing companies. The findings provide valuable insights for researchers, industry professionals, and decision-makers in understanding the current state and future prospects of IM technology.
