Source: FAQ (MPEP-Based)BlueIron Update: 2024-09-30

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.

Supplemental responses in ex parte reexamination proceedings are addressed in 37 CFR 1.111(a)(2). While they are not entered as a matter of right, the Office may enter a supplemental response if it is clearly limited to specific circumstances:

  • Cancellation of claims
  • Adoption of examiner suggestions
  • Placing the proceeding in condition for Notice of Intent to Issue Reexamination Certificate (NIRC)
  • Responding to an Office requirement made after the first response
  • Correction of informalities
  • Simplification of issues for appeal

The MPEP states: “When a supplemental response is filed in sufficient time to be entered into the reexamination proceeding before the examiner considers the prior response, the examiner may approve the entry of a supplemental response if, after a cursory review, the examiner determines that the supplemental response is limited to meeting one or more of the conditions set forth in 37 CFR 1.111(a)(2)(i).
