What is the purpose of C* designations in patent application classification?
C* designations play a crucial role in the classification of patent applications at the USPTO. According to MPEP 909.01(b):
“Every nonprovisional utility application, new or amended, and including the drawings, if any, when first received by the USPTO must be fully classified and have C* designations assigned to those CPC symbols on the application that represent the subject matter claimed.”
The purpose of C* designations is to:
- Identify the specific CPC symbols that represent the claimed subject matter
- Facilitate accurate routing of applications to appropriate examiners
- Ensure that applications are classified according to their inventive content
These designations help streamline the examination process by ensuring that applications are directed to examiners with the relevant expertise in the specific technological areas covered by the claims.
