由于外观设计专利与发明、实用新型专利在保护目的、保护对象及侵权判定方法上存在根本差异,加之外观设计领域存在的家族类似这一特殊规律,现有设计抗辩与现有技术抗辩遵循不同的逻辑和判断方法。审查现有设计抗辩时,需要在外观设计专利、被诉侵权设计及现有设计之间进行三者对此,且需要遵循正确的对比方法。 As there are fundamental differences between the design patents and inventions and utility model patents in terms of the purpose of protection, the object of protection and the method of judging the infringement, and the existence of similar families in the field of design, the existing design defense and the prior art defense follow different Logic and judgment methods. When reviewing existing design defenses, there is a need to do this between the design patent, the allegedly infringing design and the existing design and to follow the correct method of comparison.
