作者介绍了在专利审查过程中判断中药提取物新颖性的基本原则,以及在提取物与现有技术无法区分时如何试图证明提取物的新颖性,如何降低技术方案丧失新颖性的风险。申请人在提出专利申请前检索现有技术,在初步判断提取物具备新颖性的前提下提出申请,可以提高专利申请授权的可能性,减少公开了技术方案而不能获得权利这种情况的发生。 The authors present the rationale for judging the novelty of herbal extracts during patent examination and how to try to prove the novelty of the extract when the extract is indistinguishable from the prior art and how to reduce the risk of loss of novelty of the technical solution. Before the patent application is filed, the applicant searches the existing technology and makes an initial application to determine the novelty of the extract, which increases the possibility of authorizing the patent application and reduces the possibility of obtaining the right to disclose the technical solution.
