Why are assignment documents not placed directly in application or patent files?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

Assignment documents are not placed directly in application or patent files to ensure proper recording and management. According to MPEP 318:

“Assignment documents submitted for recording should not be placed directly in application or patent files, but should be forwarded to Assignment Division for recording.”

This practice serves several purposes:

• It ensures that assignments are properly recorded by the specialized Assignment Division.
• It maintains the integrity and organization of application and patent files.
• It allows for efficient tracking and retrieval of assignment information.
