What other information can CPC scheme warnings provide?

CPC scheme warnings can provide various types of important information related to patent classification changes. The MPEP 905.01(a)(3) states:

“A warning also may be used to indicate the deletion or transferring of CPC groups and reclassification notices.”

This means that warnings can alert patent examiners and researchers to structural changes in the CPC system, such as the removal or relocation of certain classification groups, as well as provide notices about ongoing reclassification efforts.
