What is the “inventive information” in CPC classification?

The “inventive information” in CPC classification refers to novel and non-obvious technical features of an invention. According to MPEP 905.03(b), “Inventive information is defined as technical information in the disclosure of a patent document which represents a contribution to the state of the art.” This information is crucial for determining the appropriate classification of a patent document.

The MPEP further explains that inventive information typically includes:

• Technical features that define a contribution the invention makes over the prior art
• Novel and non-obvious aspects of the invention
• Information that could be useful for search purposes

Examiners and classifiers use this inventive information to assign the most relevant CPC symbols to patent documents, ensuring accurate classification and efficient prior art searches.
