Can I submit an ex parte reexamination request by fax?
No, you cannot submit an ex parte reexamination request by fax. The MPEP clearly states:
“A request for ex parte reexamination may not be sent by facsimile transmission (FAX). See 37 CFR 1.6(d)(5).”
This prohibition also applies to corrected or completed requests sent in response to a notice of non-compliance. However, subsequent correspondence in ex parte reexamination proceedings can be faxed to the Central Reexamination Unit at (571) 273-9900.
