What is the Classification Challenge Procedure in CPC?
The Classification Challenge Procedure in CPC is a process where patent examiners can challenge the designated CPC (Cooperative Patent Classification) symbols on a nonprovisional utility patent application if they believe the classifications are incorrect. According to MPEP 909.01(d):
“When, in the opinion of the assigned examiner, the C* designated CPC symbol(s) on a nonprovisional utility patent application are incorrect, they must initiate a C* challenge through the Classification Allocation Tool (CAT) and complete the C* challenge form indicating any and all challenges to any C* designations including suggested additions of C* designations.”
This procedure ensures that patent applications are properly classified, which is crucial for efficient searching and examination.
