根据我国现行专利法第七十条、商标法第五十六条规定,“不知道”是免除被控侵权人赔偿责任的必要条件之一。在知识产权诉讼中,被控侵权人往往以不知道侵犯他人知识产权为由,抗辩其行为不构成侵权或者不应当承担赔偿责任。由于我国专利法、商标法以及著作权法对“不知道”是否属于免责条件的规定有所不同,在某些情况下该抗辩理由得到法院支持,而在另一些情况下则得不到支持。而目前司法解释并没有对“不知道”的具体含义、适用范围等予以解释,故实践中对“不知道”的理解和适用存在一定程度的混乱。本文试 According to Article 70 of the current Patent Law of China and Article 56 of the Trademark Law, “Do not know ” is one of the necessary conditions for exempting the accused infringer of liability for compensation. In intellectual property litigation, accused infringers often do not know infringement on the grounds of intellectual property infringement, defense of their behavior does not constitute infringement or should not be liable for compensation. Due to the fact that our patent law, trademark law and copyright law are different from the provisions on whether the “do not know” is exempted from liability, in some cases the defense is supported by the court and not supported under other circumstances . At present, judicial interpretation does not explain the specific meaning and scope of application of “do not know ”, so there is some confusion in practice about the understanding and application of “do not know ”.
