专利视域下元宇宙技术发展现状以及创新合作网络分析

Analysis of Metaverse State of the Art and Innovation Cooperation Network from the Perspective of Patent

摘要: 本文从专利申请状态分布与演化的视角，分析元宇宙专利技术的整体发展态势及其变化，进一步促进未来元宇宙产业的专利市场布局。本文基于专利数据库，采集2003~2023年6月相关专利数据，对所获得的数据进行预处理，并对该技术领域专利的申请趋势、专利申请人、专利申请国别、核心技术分类等特征进行分布和演化分析，并分析不同时间段下元宇宙技术社会合作网络关系的演化。通过专利信息结合本文的分析方法，结果显示：1) 元宇宙专利技术申请量持续增长，高产申请人多数为互联网科技企业；2) 中美在元宇宙领域优势突出，中国专利申请量大但跨地域合作少，美国专利布局全球。元宇宙技术包括多个高精尖数智技术领域，应用广泛；3) 全球元宇宙专利合作网络规模扩大，但分散度高，专利合作网络缺乏多元化创新合作，存在核心节点、次核心节点及边缘节点的层次结构。

Abstract: This article analyzes the overall development trend and changes of metaverse patent technology from the perspective of the distribution and evolution of patent application status, in order to further promote the layout of the patent market in the future metaverse industry. This article is based on a patent database to collect relevant patent data from 2003 to June 2023, preprocess the obtained data, and analyze the distribution and evolution of patent application trends, patent applicants, patent application countries, core technology classifications, and other characteristics in this technology field. It also analyzes the evolution of social cooperation network relationships in the metaverse technology at different time periods. By combining patent information with the analysis method in this article, the results show that: 1) the number of patent applications for metaverse technology continues to grow, with the majority of high-yield applicants being internet technology enterprises; 2) China and the United States have outstanding advantages in the metaverse field, with a large number of Chinese patent applications but limited cross regional cooperation. The United States has a global patent layout. Metaverse technology includes multiple fields of high-precision and cutting-edge digital intelligence technology, with wide applications; 3) The global meta universe patent cooperation network has expanded in scale, but has a high degree of Dispersity. The patent cooperation network lacks diversified innovation cooperation and has a hierarchical structure of core nodes, sub core nodes and edge nodes.
