What is the primary purpose of classification in CPC?

The primary purpose of classification in the Cooperative Patent Classification (CPC) system is to facilitate the retrieval of technical subject matter. As stated in MPEP 905.03:

“The primary purpose of classification is to facilitate the retrieval of technical subject matter. In order to reliably retrieve technical subject matter using the CPC classification system it is important for all technical subject matter to be consistently classified.”

Consistent classification ensures that users can effectively search and locate relevant technical information within the patent database.
