专利侵权等同原则中“容易联想”要件的适用研究
Research on the Application of “Be Easy to Associate” of the Doctrine of Equivalents in Patent Infringement

“容易联想”作为等同原则的要件之一，因其在司法适用中的主观随意性与模糊性而饱受学界质疑。“容易联想”要件的适用应当遵循公示与公信的原则，同时也不能脱离弥补专利申请人语言局限性的初衷。本领域普通技术人员应当以被控侵权专利技术方案与涉案专利权利要求的内容为判断依据，基于二者的技术手段判断能否产生“技术启示”，判断时间以被诉侵权行为发生时为准，发挥“容易联想”要件对其他要件的限制作用。
As one of the requirements of the doctrine of equivalents, “be easy to associate” has been questioned by scholars for its subjective randomness and fuzziness in judicial practice. “Be easy to associate” should be applied in accordance with the principle of public summons and public trust, and cannot deviate from the original intention that makes up for the language limitation of patent applicants. Ordinary technicians skilled in the art ought to judge whether “technical inspiration” can be produced based on the contents of the technical scheme accused of patent infringement and the patent claims involved in the case as well as the technical means of them. The time of judging shall be the time when the alleged infringement occurs, and the “be easy to associate” requirement should play a limiting role on other requirements.
