The Issue Classification sheet plays a crucial role in patent examination by providing a standardized way to categorize and organize patent documents. According to MPEP 1302.10, the Issue Classification sheet:

The Issue Classification sheet is automatically populated with the Cooperative Patent Classification symbols applied to a family of documents (continuations, divisionals, and/or foreign documents in the family).

This automation ensures consistency in classification across related patent documents. The Issue Classification sheet serves several important purposes:

• It helps examiners and researchers quickly identify the technical field of the invention
• It facilitates efficient prior art searches
• It aids in organizing and retrieving patent documents
• It ensures proper routing of applications within the patent office

By providing a standardized classification, the Issue Classification sheet contributes to the overall efficiency and accuracy of the patent examination process.
