摘　　要：[研究目的]近年来全球专利诉讼案件逐渐频发,涉案金额也日渐巨大,专利诉讼风险不断加剧,严重影响了企业的创新战略和发展前景。因此,亟需对专利诉讼进行研究,提升知识产权保护能力。[研究方法]利用美国专利商标局公开的数据库,全面收集美国专利的实体地位、美国母案专利申请数、外国优先权、PCT申请、权利要求数目、CPC分类数、美国专利引文数等申请阶段的解释变量信息进行对照研究、回归分析与稳健性检验,从源头上揭示专利申请特征与专利诉讼之间的关系。[研究结论]虽然在表现上略有差异,但实体地位、美国母案专利申请数、外国优先权、PCT申请、权利要求数目、CPC分类数、美国专利引文数均能显著影响专利诉讼的发生概率,能为中国企业提前降低专利诉讼风险提供一定的参考。[Research purpose]Intellectual property protection affects the quality of the supply system and the high-quality development,however,patent litigation cases occurred more and more frequently,and the amount involved has been on the rise in recent years.The risk of patent litigation in the global market continues to increase.Patent litigation not only involves legal disputes,it also can affect the enterprises'innovation strategies and development prospects.Therefore,there is an urgent need to conduct research on patent litigation to improve the ability of intellectual property protection.[Research method]We use the database published by the United States Patent and Trademark Office to collect the explanatory variable information of the patent application stage,such as the entity status,the number of U.S.parent applications,foreign priority,PCT applications,the number of claims,the number of CPC subclasses,and the number of U.S.patent citations,etc.We try to reveal the relationship between application characteristics and patent litigation directly by using control study and regression analysis.[Research conclusion]The results show that although there are some differences in performance,the entity status,the number of U.S.parent applications,foreign priority,PCT applications,the number of claims,the number of CPC subclasses,and the number of U.S.patent citations can significantly affect the probability of patent litigation.Characteristics provide some reference for Chinese enterprises to reduce the risk of patent litigation in advance.
