Abstract:From global 5 G technology research and development background, combed the United States, the European Union, South Korea and other major countries in the field of 5 G elated technical policies planning and research projects, through analyzing the patent data of 5G technology, it reveals the development history and patent activity characteristic and innovation trend of 5 G technology research, and provides an important scientific reference for formulating industry development policies. By using PatSnap patent information retrieval tool to conduct statistical analysis on the annual application trend of 5 G patents, patentee competitiveness, IPC classification and core patents, and obtain important information such as the research and development status, technology distribution and patent layout of the technology. According to the above analysis, global 5G technology research and development is in a period of rapid development. In recent years, China has emerged as a new force with a large number of patents in this field, but the vast majority of core patents are in the hands of researchers from the United States and Japan. Domestic enterprises and research institutes should increase research and development of 5G core technology and patent application and protection.
