Which types of patents still receive USPC classifications?
While most patents have transitioned to the Cooperative Patent Classification (CPC) system, certain types of patents still receive classifications within the U.S. Patent Classification System (USPC). As stated in MPEP 902:
“Only U.S. design and plant patents and U.S. plant patent application publications continue to receive classification within the USPC.”
This means that inventors and patent professionals working with design or plant patents should continue to be familiar with the USPC system, as it remains relevant for these specific types of intellectual property.
