专利法第五十九条第一款规定:发明或者实用新型专利权的保护范围以其权利要求的内容为准。权利要求能否准确而合理地界定请求保护的技术方案,是专利制度正常运作的基本保障。专利法第二十六条第四款规定的权利要求清楚,则是这是专利法对权利要求的最基本的规定。本文中,笔者针对权利要求撰写中的否定性描述形式是否会造成权利要求的保护范围不清楚进行分析,并结合五个具体案例进行讨论。提出否定性描述是否会导致权利要求不清楚的几种判断原则,并对权利要求的撰写提出建议。
Paragraph 1 of Article 59 of the Patent Law stipulates that the scope of the patent right for an invention or utility model shall be subject to the contents of its claim. Whether the claims can accurately and reasonably define the technical solutions requested for protection is the basic guarantee for the normal operation of the patent system. The clear requirement of the rights provided for in Article 26 (4) of the Patent Law means that this is the most basic requirement of the patent law for the claim of rights. In this article, the author analyzes whether the form of negative description in claim writing will make the scope of protection of the claims unclear, and then discusses five specific cases. Propose whether the negative description will result in several judgments on the unclear claims and make suggestions on how to write the claims.
