What are the requirements for separate papers in USPTO correspondence?

The USPTO requires that different matters be submitted in separate papers to avoid confusion and delays. This requirement is outlined in 37 CFR 1.4(c), which states:

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.

Key points to remember:

  • Each distinct subject, inquiry, or order should be in a separate paper.
  • This applies to both patent and trademark correspondence.
  • Exceptions are allowed for subjects provided for on a single Office or World Intellectual Property Organization form.

If you submit multiple subjects in a single paper, the USPTO may use Form Paragraph 5.01.01 to notify you of the requirement for separate papers in future correspondence.

Adhering to this requirement helps ensure that your correspondence is processed efficiently by the appropriate Office branches or sections.
