IPA patent 4.2.2.6.1-information-value-of-the-allocation — IP Australia Patent Manual of Practice and Procedure – 4.2.2.6.1 Information Value of the Allocation

Also in this Chapter: 4.2.2.6.2 Allocation of C-Sets to a Document 4.2.2.6.3 C-Sets Syntax Rules 4.2.2.6.4 Guidance about C-Sets Information in Scheme and Definitions Related Chapters: 4.2.2.1 invention information or additional information Each CPC allocation carries an “information value”. It applies to C-Sets as well. In each C-Set, the base symbol determines the information value as a whole. Hence, if the base symbol is a main trunk symbol, then the information value of the C-Set can be invention information or additional information (see 4.2.2.1 invention information or additional information for additional detail). If the base symbol is an indexing code, then the information value of the C-Set can only be additional information. Examples 1. G01N30/64, G01N30/70 INV or ADD In this example, since the base symbol is from the main trunk, the information value of the C-Set can be either INV or ADD (depending on the contribution to the prior art). 2. G01N30/64, G01N2030/8881 INV or ADD In this example, a breakdown indexing code, G01N2030/8881, is listed among the C-Set symbols as a subsequent symbol. The information value of the C-Set can be either INV or ADD, because the base symbol is from the main trunk. 3. G01N2030/025, G01N30/70 ADD In this example, since the base symbol is an indexing code, the information value of the C-Set can only be ADD (even if the subsequent symbol G01N30/70 belongs to the main trunk).
