专利侵权的合法来源抗辩——孙俊义与郑宁侵害实用新型专利权案

On the Defense of Legal Source to Patent Infringement

被诉侵权人主张合法来源抗辩必须具备法定条件,专利权人最易获得也最为有效的对抗方式是,在起诉前向被诉侵权人送达侵权警告(通知)函,以证明被诉侵权人主观上知道其行为已经构成专利侵权。侵权警告(通知)函必须记载和/或附加充分必要信息且在起诉前送达,否则,专利权人不能阻止被诉侵权人的合法来源抗辩成立,而只能向专利侵权产品的制造商即专利侵权源头主张损害赔偿。

The accused infringer must have statutory conditions for his defense of legal source. The most accessible and effective way for the patentee to fi ght against the defense is to send the infringement warning (notice) letter to the accused infringer before the prosecution, which proves that the accused infringer subjectively knows his patent infringement. The infringement warning ((notice) letter must record and/or attach sufficient necessary information and had been sent to the accused infringer before the prosecution. Otherwise, the patentee can not prevent the defense of legal source from establishing, but can claim damages to the manufacturer of the patent infringing products who is the source of patent infringement.
