What is the requirement for separate papers when corresponding with the USPTO?

The USPTO requires that different matters be submitted in separate papers to ensure efficient processing. This requirement is outlined in MPEP 501, which cites 37 CFR 1.4(c):

Since different matters may be considered by different branches or sections of the Office, each distinct subject, inquiry or order must be contained in a separate paper to avoid confusion and delay in answering papers dealing with different subjects.

This means that if you have multiple requests or inquiries for the USPTO, each should be submitted on its own separate document. For example, a petition and an information disclosure statement should not be combined into a single paper.

If an applicant submits a single paper containing distinct subjects, the USPTO may use the following form paragraph to notify them:

The [1] submitted [2] should have been submitted as a separate paper as required by 37 CFR 1.4(c). The paper has been entered. However, all future correspondence must comply with 37 CFR 1.4.

Adhering to this requirement helps ensure that your correspondence is processed efficiently and reaches the appropriate department within the USPTO.
