Or. R. Civ. P. 60
Motion for a directed verdict. Any party may move for a directed verdict at the close of the evidence offered by an opponent or at the close of all the evidence. A party who moves for a directed verdict at the close of the evidence offered by an opponent may offer evidence in the event that the motion is not granted, without having reserved the right so to do and to the same extent as if the motion had not been made. A motion for a directed verdict which is not granted is not a waiver of trial by jury even though all parties to the action have moved for directed verdicts. A motion for a directed verdict shall state the specific grounds therefor. The order of the court granting a motion for a directed verdict is effective without any assent of the jury. If a motion for directed verdict is made by the party against whom the claim is asserted, the court may, at its discretion, give a judgment of dismissal without prejudice under Rule 54 rather than direct a verdict.
