《专利法实施细则》必要技术特征条款解读

Interpretation of the Clause of Essential Technical Features of the Implementing Regulations of the Patent Law

【目的】加深对《专利法实施细则》必要技术特征条款的理解,为专利申请文件撰写和专利审查提供参考。【方法】以相关规定为基础,结合实际案例,梳理有关必要技术特征的一些关键问题。【结果】必要技术特征条款中的“技术问题”指的是说明书发明内容部分记载的技术问题,但在该条款的实际适用中,技术问题的认定存在一定的灵活性;必要技术特征条款与《专利法》第二十六条第四款存在竞合。【结论】在判断某一技术特征是否为必要技术特征时,不仅要考虑说明书中记载的技术问题,还需要考虑说明书的整体内容;申请人在撰写独立权利要求时,可以对技术方案进行合理概括,而不是必须包含所有的技术细节。

[Purposes]The objective of this study is to deepen the understanding of the clause of essential technical features of the Implementing Regulations of the Patent Law through analysis,and to provide ref⁃erence for the drafting of patent application documents and patent examination.[Methods]Based on rel⁃evant provisions and practical cases,key problems related to essential technical features were discussed.[Findings]The"technical problem"in the clause of essential technical features refers to the technical problem disclosed in the contents of the invention part of the description,but in the practical application of the clause,there is a certain degree of flexibility in the determination of the technical problem;there is overlap between the clause of essential technical features and Article 26.4 of the Patent Law.[Conclu⁃sions]When judging whether a technical feature is an essential technical feature,it is necessary to con⁃sider not only the technical problem disclosed in the description,but also the overall content of the de⁃scription;when drafting independent claims,the applicant may reasonably summarize the technical solu⁃tion,rather than including all the technical details.
