DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . STATUS OF CLAIMS This Final action is in reply to the amendment 17956172 filed on 08/19/2025. Claims1, 8 and 14 are amended Claims 1 – 20 are pending and examined Response to Arguments 112a rejection The applicant has amended the claims, the rejection is obviated. 103 rejection The examiner states that the applicants amendment for independent claim that include the housing having a lower hollow frame and a top hollow frame is still not persuasive. Based on broadest reasonable interpretation, bennet still discloses of the frame structure of a lower frame and top frame as stated in the rejection below. REED discloses of the material construction of which the material is hollow. Such that based on the current combination of references of BENNETT / LANDRY and REED, the frames are still hollow at the lower and top parts of the frame. The rectangular rod is supported directly by the lower hollow frame as show in figure 1. The applicant argues that the BENNETT / LANDRY do not disclose a rectangular rod supported directly by the lower hollow frame. This is not persuasive based on the current combination of references. LBENNETT / LANDRY / REED discloses the lower hollow frame, as BENNETT discloses the lower portion of the frame made from steel, and REED discloses steel that explicitly discloses hollow steel frame.The applicant argues that BENNET cannot be combined with the box blade from LANDRY because 107 extends below the frame 103. This is not persuasive because based on the combination, the box blade would attach to the frame itself in place of the teeth 107 extending below the frame 103 as taught in the 103 combination below. The applicant argues that the references do not disclose of a rectangular rod attached to the bottom hollow frame of the housing. The examiner states that BENNETT discloses of the bottom frame portion and REED discloses the hollow frame. Based on the combination below, the examiner states that the limitations are still taught by the existing combination. Claim 14 also discloses of rectangular rod supported directly by the bottom hollow frame and states that this is also taught by the above reasons. The applicant argues that BENNETT , LANDRY , REED does not teach of a device wherein the rectangular rod us supported directly by the lower frame. This is not persuasive as for the reasons above. The examiner states that the applicants amendments and subsequent arguments are not persuasive for the reasons stated above. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
