Response After Non-Final
This Office action is in response to the amendment filed on 7/27/2026.
Claims 1-19 are pending in the application.
Claims 1-19 are rejected.
Claims 1-2, 8-9, and 13-14 are currently amended.
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 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.
Response to Arguments
The applicant's arguments filed July 27, 2026 have been fully considered
and are respectfully found persuasive in part and unpersuasive in part.
The applicant argues the following:
[1] Title, 112 rejection, and claim objections have been addressed and should be withdrawn.
[2] Prior art of record fails to teach a virtual line inclination and a shorter distance between a second electrode tip end and a first electrode base on one side of structure and a longer distance between a second electrode tip end and a first electrode base on an other side of structure.
[3] No reason to modify.
Regarding [1], the examiner respectfully agrees and the title, 112 rejection, and claim objections raised in the most recent office action are hereby withdrawn. A new typo has been found and noted below.
Regarding [2], the examiner respectfully disagrees because the inclination of a virtual line is an imaginary inclination and the different distances are broad and varies by where along a tip or along a base the measurement is taken. Here, it is not claimed that the structure, the fingers, and the tips are themselves inclined, but rather, it is only claimed that an imaginary line is inclined. Moreover, the prior art or record includes imaginary inclined lines connecting tips and teaches the distances are longer or shorter depending on where the measurement is taken.
Regarding [3], the examiner respectfully disagrees because an obvious rejection has not been filed.
DETAILED ACTION
Drawings
The drawings are objected to under 37 CFR 1.83(a). The drawings must show
every feature of the invention specified in the claims. Therefore, the "…a distance between the tip end of one of the pair of second electrode fingers provided on one side of the corresponding one of the plurality of first electrode fingers, and a base end of the corresponding one of the plurality of first electrode fingers is shorter than a distance between the tip end of another of the pair of second electrode fingers provided on an other side of the corresponding one of the plurality of first electrode fingers and the base end of the corresponding one of the plurality of first electrode fingers, and an inclination direction is toward a direction in which the distance is longer in the first virtual line;…” in Claims 1 and 8 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered.
Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
Claim Rejections - 35 USC § 101
Double Patenting (Same Invention)
A rejection based on double patenting of the “same invention” type finds its
support in the language of 35 U.S.C. 101 which states that “whoever invents or discovers any new and useful process... may obtain a patent therefor...” (Emphasis added). Thus, the term “same invention,” in this context, means an invention drawn to identical subject matter. See Miller v. Eagle Mfg. Co., 151 U.S. 186 (1894); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Ockert, 245 F.2d 467, 114 USPQ 330 (CCPA 1957).
A statutory type (35 U.S.C. 101) double patenting rejection can be overcome by canceling or amending the claims that are directed to the same invention so they are no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101.
Claims 1, 3-7, 9-12, and 15-19 are provisionally rejected under 35 U.S.C. 101
as claiming the same invention as that of claim 1, 3-7, 12, and 15-19 of copending Application No. 18099986. This is a provisional statutory double patenting rejection since the claims directed to the same invention have not in fact been patented.
Double Patenting (Obvious)
The nonstatutory double patenting rejection is based on a judicially created
doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the "right to exclude" granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428,46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046,29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the conflicting application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement.
Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b).
Claims 2, 8, and 13-14 are provisionally rejected on the ground of
nonstatutory double patenting as being unpatentable over claims 2, 8, and 13-14 of copending Application No. 18099986. Although the claims at issue are not identical, they are not patentably distinct from each other because claims 2, 8, and 13-14 of 18099987 are anticipated by claims 2, 8, and 13-14 of 18099986. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
