摘要：随着我国知识产权制度日趋完善，专利诉讼日益成为企业参与市场竞争和技术博弈的关键工具，尤其对后发企业形成显著的技术遏制。如何在技术困境中实现逆势突围，对后发企业转被动为主动、构建核心竞争力具有重要意义。本文从组织学习理论视角出发，围绕专利被诉后企业如何实现技术追赶这一问题进行了理论推演和实证检验，并提出以下核心发现：专利被诉能够正面激发企业技术追赶。路径分析表明，进取型搜索和防御型搜索在企业被诉与技术追赶的正向关系中起到了显著中介作用。此外，创新绩效落差状态的持续时间显著调节了专利诉讼与进取型搜索之间的关联性。本文将专利诉讼、知识搜索路径与技术追赶置于同一框架，深化了企业在创新困境中的响应行为研究，为后发企业在专利诉讼情境下实现技术追赶提供了重要的理论依据与实践参考。

Abstract: As China's intellectual property rights system becomes increasingly sophisticated, patent litigation has increasingly become a key tool for enterprises to participate in market competition and technological competition, especially for latecomer enterprises, which has a significant technological containment effect. How to achieve a reverse breakthrough in technological predicaments is of great significance for latecomer enterprises to turn from passive to active and build core competitiveness. This paper, from the perspective of organizational learning theory, conducts theoretical deduction and empirical verification on how enterprises can achieve technological catch-up after being sued for patents, and puts forward the following core findings: being sued for patents can positively stimulate technological catch-up of enterprises. Path analysis shows that both aggressive search and defensive search play a significant mediating role in the positive relationship between being sued and technological catch-up. In addition, the duration of the innovation performance gap state significantly moderates the relationship between patent litigation and aggressive search. This paper places patent litigation, knowledge search paths and technological catch-up in the same framework, deepening the research on the response behavior of enterprises in innovation predicaments, and providing important theoretical basis and practical reference for latecomer enterprises to achieve technological catch-up in the context of patent litigation.
