How does the USPTO determine the proper CPC classification for a new patent application?

The USPTO determines the proper CPC classification for a new patent application through a multi-step process:

1. Initial Review: The application is reviewed to understand its subject matter.
2. Pre-Classification Search: A search is conducted to identify relevant CPC symbols.
3. Symbol Selection: The most appropriate CPC symbols are selected based on the invention’s technical features.
4. Primary Classification: The main inventive concept is assigned a primary CPC symbol.
5. Additional Classifications: Secondary CPC symbols may be assigned for additional aspects of the invention.

As stated in MPEP 909.01(a), “The examiner should carefully compare the title and the claimed subject matter with the scope of the definitions of the CPC group, subgroup, and main group to which the application is preliminary classified.” This ensures accurate classification and proper routing of the application within the USPTO.
