标准必要专利的分布特征是国家和企业战略布局的重要体现。本文基于欧洲电信标准化协会中5G标准必要专利相关数据，从5G 标准必要专利披露数量、地理位置分布、技术领域分布三个方面比较分析了中国与美国、欧盟、日本和韩国等国家或地区之间的差异。研究发现：（1）中国5G标准必要专利披露数位居第一，但是5G技术涉及标准数量与欧盟相比仍有差距；（2）中国5G标准必要专利地理位置布局以本国为主，市场分布不广；（3）中国的5G技术优势主要集中在无线通信网络、信息传输等方面，美国、欧盟等国家或地区的技术优势不仅包括无线通信、信息传输等领域，还涵盖了传感器、芯片等关键技术。该研究对于了解中国5G标准必要专利发展现状，推进中国5G专利国际布局有重要意义。

The distribution characteristics of standard essential patents is an important embodiment of the strategic layout of a country and an enterprise.Based on the relevant data of 5G standard essential patents from the European Telecommunication Standardization Association, this paper compares and analyzes the differences between China and the United States, the European Union, Japan and South Korea in terms of the number of 5G standard essential patents disclosed, geographical location distribution, and technical field distribution.The results show that :(1) China ranks first in the number of necessary patents disclosed for 5G standards, but there is still a gap between China and the EU in the number of standards involved in 5G technology;(2) The geographical distribution of China's 5G standard essential patents is mainly in China, and the market distribution is not wide;(3) China's 5G technology advantages mainly focus on wireless communication network and information transmission, while the technological advantages of the United States, the European Union and other countries or regions not only include wireless communication and information transmission, but also cover key technologies such as sensors and chips.The research of this paper is of great significance for understanding the development status of China's 5G standard essential patents and promoting the international layout of China's 5G patents.
