一般认为,在专利权利要求的撰写中,采用功能性技术特徵表述技术方案,可以获得较宽的保护范围。本文认为,发明人不可能创造出能够实现所述功能的所有技术方案,若给予权利人与功能性特徵字面含义相一致的保护,则很可能超出其对社会的项献,并且不恰当地限缩了在后创新的空间。本文通过典型案例的分析,诠释了功能性特徵解释中所应遵循、追求和采用的法律理念、政策目标和解释方法。
Generally believed that in the drafting of patent claims, the use of functional technical features that technical solutions, you can get a wider scope of protection. This paper argues that it is impossible for the inventor to create all the technical solutions that can achieve the described functions. If the obligee is given protection consistent with the literal meaning of the functional characteristics, it is likely to exceed its contribution to the society and inappropriately limit Reduced space for innovation in the post. Through the analysis of typical cases, this paper interprets the legal concepts, policy objectives and explanation methods that should be followed, pursued and adopted in the interpretation of functional features.
