【摘要】 专利权是推定有效的。虽然专利法没有总括性条款明确规定可专利性的授权要件,但第45条规定的宣告专利权无效的要件明确了授予专利权的必要要件,其基本的证明方法是在法律上进行有效性推定。该规则起源于普通法中的推定概念并被纳入了成文法规范。美国专利法实践中,将有效性推定规则与司法确权程序中的专利权效力证明标准紧密关联,构建了专利行政确权与司法确权程序之间的衔接机制。专利有效性推定规则是专利授权确权的基本证明方法,解决了证明责任的分配问题,当属于可辩驳的推定,是法律上的权利推定规范,其功能在于降低专利审查部门的证明难度,法律效果体现为证明责任转移。更多还原

【Abstract】 There is no general clause in the Patent Law that explicitly defines the elements of patentability. However, the requirements for the invalidation of a patent right as stipulated in article 45 specify the necessary elements for granting a patent right. The basic method of proof is to presume the legal validity. Legal presumption is one of the basic methods of proof. Presumption of patent validity arises from the concept of presumption in common law and is incorporated into statutory norms. In the practice of US Patent Law, presumption of validity is closely related to the proof of patent validity subject to the judicial review procedure, and a connection mechanism between patent administrative confirmation procedure and judicial confirmation procedure is constructed. The rule of presuming of validity for patent is the basic proof method for patent granting and confirmation, solving the problem of evidential burden distribution. The presumption of validity for patent is a legal norm for presuming rights, which is rebuttable. Its main function is to reduce the work difficulty for patent review department, and its legal effect is shifting the burden of proof.更多还原
