A method is presented to analyze quantitatively the degree of congenericity of claimed compounds in patent applications. The approach successfully differentiates patents exemplified with highly congeneric compounds of a structurally compact and well defined chemical series from patents containing a more diverse set of compounds around a more vaguely described patent claim. An application to 750 common patents available in SureChEMBL, SureChEMBLccs and ChEMBL is presented and the congenericity of patent compounds in those different sources discussed.
本文提出了一种定量分析专利申请中同族化合物相似度的方法。该方法成功地区分了具有结构紧凑且定义明确的化学系列的高度同族化合物的专利与围绕描述较模糊的专利主张具有更多样化化合物的专利。本文介绍了对 SureChEMBL、SureChEMBLccs 和 ChEMBL 中 750 个常见专利的应用,并讨论了这些不同来源中专利化合物的相似度。
