可视化工具在专利分析中的应用

The Application of Visualization Tools in Patent Analysis

中国企业在多个重要行业缺乏核心技术，但又面临着寻求研发机会和研发方向的难题。文章试图通过可视化工具结合专利引证分析和文本聚类分析等方法来分析某公司对于其核心专利的保护策略，专利布局和技术发展方向。通过分析，我们发现该公司对于其核心技术有着严密的保护策略，在后续多个相关领域均申请专利以保护其技术优势。此外，我们还发现最新研发方向为通信复用技术。该结果为企业规避竞争对手核心技术，制定研发策略，寻求技术发展方向提供决策支持。

Chinese companies lack core technologies in some important industries, and it is difficult in finding new R＆D opportunities and direction. This paper attempts to find out key patent protection strategy, technology landscape and technology development direction by analyzing a sample company＇s key patents. Visualization tools combined with patent citation analysis and text clustering analysis were used in this paper. The results show that the company has excellent patent protection strategy. In order to keep its technology advantage, this company filed more patents around the key patent and these patents cover most of related fields. In addition, Division Multiplexing technology is the latest R＆D direction. These results can support an enterprise to circumvent its competitors＇ key patent, develop its R＆D strategy, find out the direction of technology development.
