Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement 1. The information disclosure statement (IDS) submitted on 12/16/2025 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Response to Amendment 2. Applicant’s amendments with respect to claims filed on 02/25/2026 have been entered. Claims 1-9 and 11-16 remain pending in this application and are currently under consideration for patentability under 37 CFR 1.104. Claim 10 has been cancelled. The amendments and remarks filed are sufficient to cure the previous Drawing Objections set forth in the Non-Final office action mailed on 11/28/2025. Claim Rejections - 35 USC § 103 3. 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. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. 4. Claim(s) 1-16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Pasma et al. (Pub. No. US 20190341587 A1) in view of Tsutsumi et al. (Pub. No. US 20170214030 A1).

It would have been obvious for one of ordinary skill in the art before the effective filing date of the invention to modify Pasma to add a projecting portion on two end surfaces of the washer body as taught by Tsutsumi to ensure sufficient sealability (see [0145] of Tsutsumi). Further Pasma teaches that modifications can be made (see [0062] of Pasma). Regarding claim 2, Pasma in view of Tsutsumi teaches wherein two end surfaces (end surface 1 and 2, Fig. 4B above) of the washer body (washer body, Fig. 4B above) are each provided with the annular protrusion (925, Fig. 6, see [0145] of Tsutsumi, see modification above).

Regarding claim 12, Pasma in view of Tsutsumi teaches wherein two end surfaces (end surface 1 and 2, Fig. 4B above) of the washer body (washer body, Fig. 4B above) are each provided with the annular protrusion (925, Fig. 6, see [0145] of Tsutsumi, see modification above). Regarding claim 13, Pasma in view of Tsutsumi teaches wherein the end portion (310, Fig. 3, see [0035]) is disposed on a side of the first washer (222, Fig. 2A, see [0034], see Fig. 2A where 310 is disposed on side of 221 away from 224) away from the second washer (224, Fig. 2A, see [0034]). Regarding claim 14, Pasma in view of Tsutsumi teaches wherein the second washer (224, Fig. 2A, see [0034]) is provided with an accommodation groove (730, Fig. 7A, see [0037]) for accommodating at least a part of the conductive terminal (226, Fig. 2A, see [0034], see [0037] where 226 is seated in 730); and a side wall (First side wall 1 and First side wall 2, Fig. 5 below) of the conductive terminal (226, Fig. 2A, see [0034]) and a groove wall (groove wall 1 and 2, Fig. 7A below) of the accommodation groove (730, Fig. 7A, see [0037]) are at least partially attached to each other (see [0037] where 226 is seated in 730, see [0034] where the rivet compresses 222, 224, and 226 into 110, therefore all the components are compressed together and therefore fastened together, so as to prevent the conductive terminal (226, Fig. 2A, see [0034]) from rotating relative to the second washer (224, Fig. 2A, see [0034], see [0037] where 226 seated in 224 prevents rotation of 226 relative to 224).

Regarding claim 16, Pasma in view of Tsutsumi teaches wherein the conductive terminal (226, Fig. 2A, see [0034]) is provided with a via hole (520, Fig. 5, see [0041]) for the shaft portion (shank, see [0035], labelled in Fig. 9A above) to pass through (see [0041] where 520 is for receiving 221), and a side of the conductive terminal (226, Fig. 2A, see [0034], side of the conductive terminal is side away from 224 and facing 226 in Fig. 2B) facing away from the second washer (224, Fig. 2A, see [0034]) is provided with an accommodating groove (540, Fig. 5, see [0042], in Fig. 5 the dashed lines indicate the accommodating region is on the opposite side of 226, as evidenced by Fig. 9A above where the 320 after assembly is on the side facing away from 224, and see [0042] 540 contacts 320 after assembly or when it is expanded) in communication with the via hole (520, Fig. 5, see [0041] where 520 receives the shank and then contacts 540, see Fig. 5 where 540 surrounds 520 on side facing away from 224). Response to Arguments 5. Applicant's arguments filed 02/25/2026 have been fully considered but they are not persuasive. Regarding applicant’s arguments that the through groove taught by Pasma cannot laterally surround a conductive plate because the edge-opening leaves one side of the plate laterally exposed to the periphery, and the internal architecture as claimed provides a closed-loop 360-degree lateral enclosure. The Examiner respectfully disagrees as the limitation of laterally surround encompasses an embodiment wherein one side is open to the periphery as it was not required that the conductive plate be completely or entirely laterally surrounded or have a closed-loop 360 degree lateral enclosure. Further, even if the claims were amended to recite such a limitation of a closed-loop 360 degree lateral enclosure, there is no support for that limitation in the instant specification or drawings. In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., closed-loop 360 degree lateral enclosure) are not recited in the rejected claim(s). Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Further, even if the claims were amended to recite such a limitation of a closed-loop 360 degree lateral enclosure, there is no support for that limitation in the instant specification or drawings. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
