中文摘要：

近年来,专利申请和专利诉讼均呈现快速增长态势,有必要厘清二者的相互作用关系。首先采用协整分析和误差修正模型,分析专利申请和专利诉讼的时间序列数据,研究表明专利申请与专利诉讼存在长期稳定的动态均衡关系;在此基础上,运用格兰杰因果检验的分析表明,专利申请与专利诉讼存在显著的相互促进作用;其中,专利申请对专利诉讼有显著的促进作用,这说明专利申请的增加将导致专利诉讼在未来的涌现;与此同时,专利诉讼对专利申请也有显著的促进作用,这意味着专利诉讼的增加将促使专利权人提出更多的专利申请。

英文摘要：

Both patent applications and patent lawsuits have increased rapidly in recent years. It is necessary to clarify the interaction between them. Co- integration and error correction model are employed to analyze the time series of patent applications and patent lawsuits. It shows that there is a long- term dynamic equilibrium relationship between patent applications and patent lawsuits. The results of Granger causality show that patent applications and patent lawsuits present a significant interaction of mutual promotion. Patent applications have a positive effect on patent lawsuits,indicating that the increase in patent applications will lead to the emergence of massive patent lawsuits in the future. Meanwhile,patent lawsuits also present a positive effect on patent applications,which means that the increase in patent lawsuits will inspire patentees to apply for more patents.
