No, a patent owner cannot be represented by a person who is not registered to practice before the United States Patent and Trademark Office (USPTO) during a reexamination proceeding. MPEP 2213 clearly states: “A patent owner may not be represented during a reexamination proceeding by any person who is not registered to practice before the Office, since those individuals are prohibited by 37 CFR 1.33(c) from signing amendments and other papers filed in a reexamination proceeding on behalf of the patent owner.” This restriction ensures that only qualified practitioners handle the complex legal and technical aspects of reexamination proceedings.
