What is the difference between invention information and additional information in CPC classification?
In CPC classification, there is a distinction between invention information and additional information. According to MPEP 909.01(a):
- Invention information refers to the technical features that represent the claimed invention’s contribution to the art.
- Additional information includes technical features that are not essential to the invention but are still considered important for search purposes.
The MPEP states, “CPC classification is based on the claimed disclosure and can be applied based on the description and drawings in addition to the claims.” This means that while the primary focus is on the claimed invention, examiners may also consider other parts of the application to assign appropriate CPC symbols for both invention and additional information.
This distinction helps in creating a more comprehensive classification that captures both the core inventive concept and other relevant technical aspects, enhancing the efficiency of prior art searches and examination processes.
