A method for quantitatively analyzing the congenericity of claimed compounds in patent applications is presented. The method successfully distinguishes patents with highly congeneric compounds from patents with a more diverse set of compounds. The method is applied to 750 common patents from SureChEMBL, SureChEMBLccs, and ChEMBL, and the congenericity of patent compounds in these different sources is discussed.
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.
