摘要:

技术特征划分是专利侵权认定的基础,立法层面对专利技术特征概念的回避和行政司法实践中不同语境、时境下权利要求解释目的差异及利益动机的变化,导致专利侵权诉讼中技术特征划分规则模糊,缺乏统一规范。基于专利技术特征构成的“单元—功能—效果” 三要件框架,以专利技术单元不可分割性与技术功效独立性的统一为标准,提出“最小技术单元分解—功效独立性判断—技术单元组合”的技术特征划分“ 三步法”,以进一步规范专利侵权诉讼中技术事实认定过程,统一裁量标准。

Abstract:

The division of technical features is the basis for judging patent infringement. The avoidance in the concept of patent technical characteristics at the legislative level and the differences in the purpose of interpretation of claims in different contexts and circumstances in administrative judicial practice and the changes in interest motives have resulted in vague rules for the division of technical features in patent infringement litigation and lack of uniform norms. Based on the three-element framework of “unit-function-effect” composed of patent technology features, taking the unity of indivisibility of patent technology unit and independence of technical efficacy as the standard, a “three-step method” is proposed for technical feature division, which involves decomposing the patent technology solution into the smallest unit, determining whether the functional effect of the smallest technology unit is independent, and combining the smallest technology unit. It is conducive to standardizing the process of determining technical facts in patent infringement litigation and unifying discretionary standards.
