Why are some sections in the MPEP marked as [Reserved]?

Sections in the Manual of Patent Examining Procedure (MPEP) are sometimes marked as ‘[Reserved]’ for several reasons:

  • To maintain consistent numbering across editions
  • To allow for future expansion of content
  • To accommodate planned updates or revisions
  • To serve as placeholders for potential new topics or guidance

This practice helps the USPTO maintain flexibility in organizing and updating the MPEP while preserving a logical structure for users.
