No, third party requesters are not permitted to file additional papers after their reply to the patent owner’s statement in an ex parte reexamination. MPEP 2251 clearly states: “The third party requester is not permitted to file any further papers after his or her reply to the patent owner’s statement. Any further papers will not be considered and will be returned to the requester.” This restriction ensures that the ex parte reexamination process remains focused and prevents potential delays or complications from additional submissions by the third party requester.
