Strategic Development of LTE Mobile Communication Technology Based on Patent Map Analysis
Information,communication,optoelectronic,and semi-conductor industry are major industries in Taiwan.In mobile communication industry,the 4th generation (4G) can be categorized into two major techniques,i.e.Long-Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WiMAX).Many 4G related patents were filed and granted globally,particularly in major markets such as US,Europe,and China,in recent years.When comparing LTE and WiMAX,LTE gradually dominates the technology landscape in 4G telecommunication development.This research depicts the LTE technology development trend and also chooses Wi-LAN Inc.as the major assignee for detailed patent map and its intellectual property rights (IPRs) analysis.The LTE patent documents in the United States Patent and Trademark Office (USPTO) database are searched.And,the research identifies 62 Wi-LAN patents as major target patents.These patents are analyzed with various patent statistic views (also called patent maps),which include the statistics of patent counts based on International Patent Classification (IPC),forward citation counts,patents in quality levels,and patents categorization in technology-function matrix.Patents are evaluated to find the high quality patents,which may lead to the litigation in the future.Finally,the technology-function matrix indicates Wi-LAN R&D focuses of the key technologies,i.e.,to improve efficiency and stability of 4G transmission.Consequently,a competitor of Wi-LAN can develop new technologies and file new patents to avoid infringing upon existing IPRs.Companies can also increase their cross-licensing opportunities when more patents were granted to them in essential and/or complementary sub-technologies.Thus,this research provides critical intelligence to the LTE-related companies for enhancing their R&D and patenting strategies.
