摘要
我国专利等同侵权的判断中,等同特征是指与所记载的技术特征以基本相同的手段,实现基本相同的功能,达到基本相同的效果,并且本领域的普通技术人员无需经过创造性劳动就能够联想到的特征。其中何谓基本相同的手段、功能、效果(三基本相同)一直存在争议,因为实践操作中缺乏确定性和可预期性,而且其中的容易想到也是实践难点。现有的研究基本集中于三基本相同的理解与完善。本文则从等同原则的起点——语言局限性出发展开研究,发现现有判断方法实质上偏离了语言局限性。为此,本文从语言局限性出发,在排除撰写不当的基础上,提出最大允许误差理论来完善判断方法。该方法以所属领域技术人员为判断主体,回归专利的技术属性,融合现有专利制度,具有更好的合理性、合法性和更强的可操作性、确定性和可预期性。
Equivalent element is the element that performs substantially the same function in substantially the same way to achieve substantially the same result as the element in the claims,and is obvious for the person skilled in the art.What is the substantially the same function,way and result is a problem that is argued through over 100 years.To solve this problem,a new framework is built to judge the equivalents on the basis of the principle of the maximum permitted tolerances and the language limitation.If the element in the object accused fall into the maximum permitted tolerances of the element in the claim,then the accused object constitute the patent infringement equivalently.
