本文从专利审查程序和诉讼程序对权利要求中功能性限定的技术特征具有不同的解释出发,分析了上述两个程序中存在不一致作法的原因。此外,从一个实际案例出发,提出专利法审查程序中对权利要求中技术特征的解读可以借鉴《最高人民法院关于审理侵犯专利权纠纷案件应用法律若干问题的解释》第二、三条的规定,对于权利要求技术特征的含义,应当结合说明书和说明书附图、以及本领域普通技术人员的公知常识加以理解,并且申请文件的内部解释效能大于外部解释的效能。
This paper starts from the different explanation of patent examination procedure and litigation procedure to the technically limited definition of the technical features in the claims, and analyzes the reasons for the inconsistency in the two procedures mentioned above. In addition, from a practical case, it is proposed that the interpretation of the technical features of the claims in the patent law review process can draw on the provisions of Articles 2 and 3 of the Interpretation of the Supreme People’s Court on Several Issues Concerning the Application of Law in the Trial of Patent Infringement Cases, The meaning of the technical features of the claims should be understood in conjunction with the description and the drawings, as well as the common general knowledge of persons of ordinary skill in the art, and the internal explanation of the application documents is more effective than the external explanation.
