“禁止反悔原则”的原理与适用——澳诺(中国)制药有限公司与湖北午时药业股份有限公司侵犯发明专利权纠纷案

Principle and Application of "Prosecution History Estoppels" in Patent Law

专利法上的"禁止反悔原则"体现了在平衡"保护范围明确化"与"权利保护周全化"两种利益上的独特作用。本文在此原理上提出在适用要件与效果上应采纳"可预见性"标准,从而恰当地排除专利权人在专利申请或专利文件修改时针对可以预见的技术方案请求等同侵权的主张。

The principle of ＂prosecution history estoppels＂ in patent law serves a unique function in balancing two different interests; on one side it fi xes the scope of right protection, and on the other side it provides adequate protection to the right. This article, based thereon, suggests that the ＂foreseeability＂ standard should be adopted both in the requirements and effects, thus properly preventing patentee from claiming for infringement under the ＂doctrine of equivalents＂ on the grounds that the technical solution in question is foreseeable when applying for the patent or modifying patent document.
