How do I file papers in an ex parte reexamination resulting from a supplemental examination?

When filing papers in an ex parte reexamination resulting from a supplemental examination, follow these guidelines as per MPEP 2806:

  • Use the USPTO’s Patent Electronic Filing System-Web (EFS-Web) or Patent Center for electronic filing.
  • For paper filings, send documents to: Mail Stop Ex Parte Reexam, Commissioner for Patents, P.O. Box 1450, Alexandria, VA 22313-1450.
  • Include the control number assigned to the reexamination proceeding.
  • Clearly mark all papers with “EX PARTE REEXAMINATION” to ensure proper routing.

The MPEP states: “Any paper filed in an ex parte reexamination proceeding resulting from a supplemental examination proceeding should be filed as provided in 37 CFR 1.1(c).” This ensures that your documents are properly processed and routed within the USPTO.
