# 1.993 Suspension of concurrent interference and reexamination proceeding.
If a patent in the process of *inter partes* reexamination is or becomes involved in an interference or trial before the Patent Trial and Appeal Board, the Director may suspend the *inter partes* reexamination, interference, or trial. The Director will not consider a request to suspend an interference or trial unless a motion under § 41.121(a)(3) of this title to suspend the interference or trial has been presented to, and denied by, an administrative patent judge and the request is filed within ten (10) days of a decision by an administrative patent judge denying the motion for suspension or such other time as the administrative patent judge may set.
