Any request for such extension must be filed on or before the day on which action by the patent owner is due, but in no case will the mere filing of the request effect any

extension. See § 1.304(a) for extensions of time for filing a notice of appeal to the U.S. Court of Appeals for the Federal Circuit or for commencing a civil action.
