How do references in CPC titles affect classification?
References in CPC titles play a crucial role in patent classification by providing guidance on the scope and relationships between different classification places. The MPEP 905.01(a)(1) explains:
“References apply to the classification place they appear and to all hierarchically lower classification places, unless stated otherwise.”
This means that references help establish a hierarchical structure within the classification system, guiding patent examiners and searchers to related or more specific categories. They can limit the scope of a classification place, point to related areas of interest, or establish precedence between similar groups, ensuring a more accurate and comprehensive classification of patent documents.
