专利诉讼中外研究现状与发展趋势

以2000—2020年WebofScience核心数据库（SSCI）和CNKI核心数据库（CSSCI）收录的669篇文献为研究样本，采取文献计量法等方法并利用R语言编程等工具对国内外专利诉讼整体脉络、研究热点演进、研究前沿等进行系统分析。结果表明，专利诉讼研究已经成为重要交叉学科研究领域，美国是专利诉讼研究的领先国家，国内外发文数量差距较大且呈加剧之势，国内已有稳定期刊群，国内各机构关注的具体议题不同；国内外研究热点演进可以分为3个阶段，现阶段国外研究表现出研究范围广、对象多元、方法前沿、程度加深等特点，而国内特征为将国外研究框架、理论方法与我国具体国情实践相结合；国内外共同研究前沿为专利蟑螂和创新，其余方面则有一定差异。基于研究结论，给出加强交叉学科研究、紧跟国际趋势、加大国情视角分析等针对性建议。

Research Status and Development Trend of Patent Litigation at Home and Abroad

Taking 669 articles published in 2000—2020 collected by web of science core database (SSCI) and CNKI core database (CSSCI) as research samples, this paper adopts bibliometrics and R language programming tools to analyze the overall context, hot research progress and research frontier of patent litigation at home and abroad. The results show that patent litigation research has become an important interdisciplinary research field. The United States is the leading country in patent litigation research, and the gap between domestic and foreign publications is increasing. There are stable journal groups in China, and the specific topics concerned by domestic institutions are different.The evolution of research hotspots at home and abroad can be divided into three stages. At the present stage, foreign research shows the characteristics of wide research scope, multiple objects, advanced methods and deepening degree, while domestic research is characterized by the combination of foreign research framework and theoretical methods with China's specific national conditions and practice.The frontier of joint research at home and abroad is patent troll and innovation, while there are some differences in other aspects.Based on the research conclusions, targeted suggestions are given to such as strengthen interdisciplinary research, keep up with international trends, and increase the analysis of national conditions.
