现有技术抗辩与无效宣告抗辩的竞合——盐城泽田机械有限公司与盐城市格瑞特机械有限公司侵犯实用新型专利权纠纷案

On the Concurrence of the Prior Art Defense and the Invalid Declaration Defense

我国2008年《专利法》和2010年《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》颁行之后,允许现有技术抗辩和无效宣告抗辩同时申请和主张,并将现有技术组合限于一项现有技术与所属领域公知常识的简单组合。现有技术抗辩和无效宣告抗辩本为互补关系,前者的引入是为了弥补后者的缺位或者缺陷,以解决专利侵权诉讼中所突出存在的周期长、效率低等问题。

After the Patent Law in2008and the Interpretation of Certain Questions Concerning the Application of Law in the Trial of Patent Infringement Disputes issued by the Supreme People's Court in2010,China allowed the application and claim of the prior art defense and the invalid declaration defense simultaneously,and limited the simple combination of a prior art and common general knowledge in its domain.The prior art defense and the invalid declaration defense are complementary.The former is introduced to remedy the defi ciency or defect of the latter so as to solve the problems of long period and low effi ciency in patent infringement litigation.
