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 . Continued Examination Under 37 CFR 1.114 1. A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 09/08/2026 has been entered. Response to Amendment 2. Applicant’s amendments with respect to claims filed on 09/08/2026 have been entered. Claims 1-5 and 11-13 remain pending in this application and are currently under consideration for patentability under 37 CFR 1.104. Claims 6-9 and 14-16 have been cancelled. 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) 1-5 and 11-13 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).

Further Pasma teaches that modifications can be made (see [0062] of Pasma). 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]). Response to Arguments 5. Applicant's arguments filed 09/08/2026 have been fully considered but they are not persuasive. Regarding applicant's argument that the Examiner's characterization misconstrues the express language of the claims and proper application of BRI because the Examiner is not giving proper patentable weight to the term "configured as an internal channel spaced apart from the peripheral edge". The Examiner respectfully disagrees, as the interpretation of claim limitations are given their ordinary and customary meaning of the terms consistent with the use of the claim term in the specification and drawings. As the terms laterally, surround, internal, channel, spaced, apart, and peripheral are not mentioned in the instant specification, the Examiner looked to the drawings to determine consistent use of the claim terms. Fig. 1 points to 501 as the through groove which is illustrated as a C-shape cutout at the lower side of 500. Further in Fig. 2 by the position of the conductive plate 300, the through groove is further illustrated as a c-shape cutout at the edge of the insulation partition. Therefore the Examiner interpreted the claim terminology under BRI as common and ordinary use of the terms consistent with the drawings. Regarding applicants argument that the spaced apart requirement is not met because the open-ended edge feature breaches the outer edge, the distance between interior perimeter of the notch and the peripheral edge of the partition at the point of entry is zero, and the claim limitation mathematically requires a continuous, non-zero boundary, therefore the Examiner's characterization of Pasma's feature is geometrically impossible from meeting the limitation. The Examiner respectfully disagrees, as the claim limitation requires the through groove to be spaced apart from a peripheral edge of the insulation partition. The insulation partition has multiple peripheral edges, including the top edge, each side edge, and the bottom edge. Therefore, since the groove in Pasma is physically distant from the top wall it is spaced apart from that peripheral edge. Further, the Applicant is arguing features and interpretations of the claim language which are not supported in the specification or drawings. Regarding the applicants argument that the requirement for a channel to be spaced apart from a peripheral edge necessitates that the channel be isolated from the boundary of the partition in its entirety, and the open ended notch requires the breaches the peripheral edge. The Examiner respectfully disagrees, as the claim did not require the internal channel be completely isolated from the entire outer boundary of the insulation partition or even spaced apart from the entire peripheral edge of the insulation partition, it required the channel to be spaced apart from a peripheral edge. Further, the Applicant is arguing features and interpretations of the claim language which are not supported in the specification or drawings. Regarding applicant's argument that because the claim required the internal channel to be spaced apart from the peripheral edge, the material boundary defining the channel must remain continuous. The Examiner respectfully disagrees as the claim did not require the entirety of the interior portion of the internal channel be spaced apart from the entire outer periphery of the insulation partition, it instead required a channel spaced apart from a peripheral edge in which it is spaced apart from multiple peripheral edges of the insulation partition in Pasma. Further, the Applicant is arguing features and interpretations of the claim language which are not supported in the specification or drawings. Regarding applicant’s argument that Pasma fails to teach or suggest the feedthrough sequence of there the conductive plate passes through the through groove to be electrically connected to the rivet because Pasma uses an indirect electrical path to the rivet. The Examiner respectfully disagrees as the claim required that the conductive plate electrically connects to the rivet and the claim does not require the conductive plate is in direct contact with the rivet. Therefore, electrically connecting through 226 is an electrical connection between 820A and 221. Regarding applicant’s argument that the internal channel spaced apart from the peripheral edge requires the opening to be spaced apart from the peripheral edge and not open to an external boundary, and this limitation is supported by the applicant’s specification in Figs. 1 and 2 and paragraph [0053]. The Examiner respectfully disagrees as the as the claim did not require the internal channel be completely isolated from the entire outer boundary of the insulation partition or even spaced apart from the entire peripheral edge of the insulation partition, it required the channel to be spaced apart from a peripheral edge. Further the applicant is arguing features and interpretations of the claim language which are not supported by the specification. Paragraph [0053] simply describes a through groove passing through the insulation partition and Figs. 1 and 2 illustrate a C-shaped cutout for the through groove 501, therefore they do not support an internal channel which does not breach the peripheral edge. Regarding applicant’s argument that the internal channel spaced apart from the peripheral edge provides the technical advantage of the insulation partition maintains complete boundary containment and preserves the structural continuity of the outer boundary and prevents edge failure and tearing vulnerabilities inherent to open-notch configurations. This argument is moot as the internal channel spaced apart from the peripheral edge as claimed does not require complete enclosure around the entire boundary of the opening, nor is such an interpretation supported by the applicants specification. Further the applicant has provided no proof or support for this supposed technical advantage. Conclusion 6.
