What are Warnings in CPC schemes and what purpose do they serve?
Warnings in CPC schemes are used to alert users about specific classification issues or changes. According to MPEP 905.01(a)(3):
“A warning is used in CPC schemes for signaling deviations from IPC or incomplete classification. A warning may include a listing of IPC groups not included within CPC and the CPC group which covers the relevant subject matter. A warning also may be used to indicate the deletion or transferring of CPC groups and reclassification notices.”
Key functions of Warnings in CPC schemes:
- Signal deviations between CPC and IPC classifications
- Indicate incomplete classifications
- Provide information on deleted or transferred CPC groups
- Notify users about reclassification efforts
Understanding Warnings is essential for patent professionals to navigate potential discrepancies or changes in the classification system accurately.
