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 .
Response to Arguments
Applicant's arguments filed 07/07/2026 have been fully considered as follows:
Applicant’s arguments, see page 9, with respect to drawings have been fully considered but they are not persuasive. The objection to the drawings is maintained as to the “cooking appliance” recited in the claims. Applicant addresses this objection only by amending the specification, stating that “the specification has been amended as above.” However, amendment of the specification does not remedy an objection to the drawings under 37 CFR 1.83(a), which requires the drawing to show every feature of the invention specified in the claims. Because no amended or corrected drawings have been submitted, and the drawings still fail to depict the cooking appliance, the objection is maintained. Corrected drawings, depicting the cooking appliance are required in reply to this Final Office Action.
Applicant’s arguments, see page 9, with respect to drawings have been fully considered but they are not persuasive. The objections to the drawings are maintained as to the “start point” and “end point” of the pattern portion recited in claims 21, 24, 26, 29-32, 36-37, and 40. Applicant asserts that Figs. 4 and 6 show these features but has not amended the drawings to add reference characters identifying them. Under 37 CFR 1.83(a), the drawings must show every feature of the invention specified in the claims. Absent reference characters in Figs. 4 and 6 specifically identifying the claimed start point and end point, the drawings fail to comply with 37 CFR 1.83(a), and applicant’s assertion that these features are otherwise visible in the figures does not cure the deficiency. Corrected drawings adding the appropriate reference characters are required in reply to this Final Office Action.
Applicant’s arguments, see page 9, with respect to specification have been fully considered and are persuasive. The objection of the specification has been withdrawn. The substitute abstract filed 07/07/2026 consists of a single paragraph of approximately 89 words, in compliance with MPEP 608.01(b), and overcomes the objection.
Applicant’s arguments, see page 9, with respect to claims 23 and 24 have been fully considered and are persuasive. The objection of claims 23 and 24 has been withdrawn.
Applicant’s arguments, see pages 9-10, with respect to the rejection of claims 21-40 under 35 U.S.C. 112(b) have been fully considered and are persuasive in part.
The rejection of claim 21, and dependent claims 22-25, is withdrawn.
The rejection of claim 23 is withdrawn.
The rejection of claim 26, and dependent claims 27 and 29-31, is withdrawn.
The rejection of claim 32, and dependent claims 33-36, is withdrawn.
The rejection of claim 39 is withdrawn.
Applicant’s arguments, with respect to claim 28, have been fully considered but they are not persuasive. Claim 28 recites “a width of a first gap between a first pair of bridges is greater than a second gap between a second pair of bridges.” The claim is indefinite because it compares a width of the first gap to the second gap itself, rather than to a width of the second gap, rendering it unclear what comparison is being claimed. Correction is required, for example by amending “is greater than a second gap” to recite “is greater than a width of a second gap,” consistent with the parallel language used in claims 23 and 39. The rejection of claim 28 is maintained.
Applicant’s arguments, with respect to claim 37 have been fully considered but they are not persuasive. Claim 37 recites “the inner most side” in the limitation “are formed to have a length increasing from the innermost side to an outer most side of the second pattern portion.” There is insufficient antecedent basis for this limitation, as no innermost side of the second pattern portion has been previously introduced in the claim. This is the same deficiency identified in the prior Office action; unlike the analogous limitation in claim 26, it has not been corrected. For the same reason, dependent claims 38-40 remain rejected as well. The rejection of claims 37-40 is maintained.
Applicant’s arguments, see page 10, with respect to the rejection of claims 21-23, 25-28, 32-35, and 37-40 under obviousness-type double patenting have been fully considered but they are not persuasive. The rejection is maintained.
Claim 21 recites a gap between a pair of bridges set to be proportional to a potential difference between the pair of bridges, and a gap between a pair of bridges located at the innermost side of the pattern portion narrower than a gap between a pair of bridges located at the outermost side of the pattern portion. These limitations are not patentably distinct from claim 1 of US 11,668,470, which recites a gap width increasing from the innermost side to the outermost side of the pattern portion, in combination with claim 3 of US 11,668,470, which recites a gap between a pair of bridges set to be proportional to a potential difference between the pair of bridges. Claims 22-25 remain rejected by virtue of their dependency from claim 21.
Claim 26 and its dependent claim 27 are not patentably distinct from claims 4, 6, and 7 of US 11,668,470 for the same reason. Claim 26 recites the first-bridges gap-increasing limitation of claim 4 in combination with the first-bridges gap-proportional-to-potential-difference limitation of claim 6, and claim 27 recites the second-bridges-gap-proportional-to-potential-difference limitation of claim 7 essentially verbatim.
Claim 32 and dependent claims 33-35 are not patentably distinct from claims 8, 10, and 12 of US 11,668,470. Claim 32 recites the third pattern portion structure of claim 8 in combination with the third-bridges gap-proportional-to-potential-difference limitation of claim 12; claim 33 recites the same innermost-gap-to-third-bridges-gap comparison as the closing limitation of claim 8; claim 34 recites the same third-bridges arc-shape-with-predetermined-width limitation as claim 11; and claim 35 recites the same second-bridges-to-third-bridges gap comparison as claim 10.
Claims 37-40 recite the same first pattern portion, second pattern portion, tracks, bridges, and gap limitations as claim 26, incorporated into a cooking appliance. Applicant argues claim 37 is patentably distinct from the reasons discussed with respect to claim 21, which is not persuasive for the reasons set forth above. Applicant does not address the Office Action’s separate findings that incorporating the claimed electric heater into a cooking appliance would have been an obvious extension of a well-known auxiliary component for household use, and that finding is maintained.
A terminal disclaimer in compliance with 37 CFR 1.321(c) is required to overcome this rejection.
Applicant’s arguments, see pages 10-11, with respect to the rejections of claims 21-40 under 35 U.S.C. 102(a)(1) and 35 U.S.C. 103 have been fully considered but they are not persuasive, except as noted below with respect to claims 23, 28 and 39.
Applicant argues that neither Meindl nor Visher, individually or in combination, discloses or suggests designing the spacing between opposing bridge pairs in proportion to the potential difference between the bridge pairs, nor discloses or suggests increasing the bridge spacing from the inner side toward the outer side of the pattern portion. This is not persuasive. The proportional-to-potential-difference limitation is addressed by official notice, unchallenged by applicant, as set forth in the rejection of record. The increasing-bridge-spacing limitation is expressly shown in annotated Fig. 2 of Meindl (Gb1 < Gb2 < Gb3) and annotated Fig. 1 of Meindl (1st gap < 2nd gap). The newly added limitations in claims 21, 26, and 37—that a gap between a pair of bridges with small potential differences is smaller than a gap between a pair of bridges with large potential differences, and that a gap located at the innermost side is narrower than a gap located at the outermost side—do not overcome this showing, being narrower instances of the same relationship already disclosed. The rejections of claims 21-22, 24-27, 29-38, and 40 are maintained.
The rejections of claims 23, 28, and 39 are withdrawn. As amended, these claims recite a first gap wider than an adjacent second gap in a direction from the innermost side to the outermost side (or from the center to a radially outer side), the opposite of the relationship shown in annotated Fig. 2 of Meindl (Gb1 < Gb2), annotated Fig. 1 of Meindl (1st gap < 2nd gap), and Fig. 7 of the instant application (G1out < G2). Because the cited art discloses the increasing relationship, not the decreasing relationship now claimed, it does not anticipate or render claims 23, 28, and 39 obvious as currently amended. Claims 23, 28, and 39 are rejected instead under 35 U.S.C. 112(a), as set forth below.
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 “cooking appliance” in claim 37, as well as the “start point” and the “end point” in claims 21, 24, 26, 29-32, 36-37 and 40 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 § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 28 and 37-40 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 28 recites “a width of a first gap between a first pair of bridges is greater than a second gap between a second pair of bridges.” The claim is indefinite because it compares a width of the first gap to the second gap itself, rather than to a width of the second gap, rendering it unclear what comparison is being claimed.
Claim 37 recites “the outermost side” in line 18. There is insufficient antecedent basis for this limitation in the claim. Claim 37 also recites “the innermost side” in line 24. There is insufficient antecedent basis for this limitation in the claim. For the same reason, its dependent claims 38-40 are rejected as well.
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claims 23, 28 and 39 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
Claim 23 recites “a width of a first gap between a first pair of bridges is greater than a width of a second gap between a second pair of bridges adjacent to the first pair of bridges in a direction from the innermost side to the outermost side of the pattern portion.” This requires the gap between an inner pair of bridges to be wider than the gap between an adjacent, more outward pair. The specification discloses the opposite relationship: Fig. 5 shows the gap between bridge pairs increasing in width moving from the innermost side to the outermost side of the pattern portion (G1in < G1 < G1out < G2). The specification does not reasonably convey that the inventor had possession of a pattern portion in which the gap decreases, rather than increases, in the outward direction. Claim 23 is rejected accordingly.
Claim 28 recites the same relationship between a first gap and a second gap in a direction from the center of the first pattern portion to a radially outer side, comparing a gap at the outermost side of the first pattern portion to an adjacent gap at the innermost side of the second pattern portion. Figs. 5 and 7 both show this boundary gap increasing in width (G1out < G2), the opposite of what is now claimed. Claim 28 is rejected for the same reason as claim 23.
Claim 39 recites the same relationship, and is rejected for the same reason.
This rejection is a new ground necessitated by applicant’s amendment to claims 23, 28 and 39.
Double Patenting
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 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); 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 nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.

Claims 21-23, 25-28, 32-35 and 37-40 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-8 and 10-12 of U.S. Patent No. US 11,668,470. Although the claims at issue are not identical, they are not patentably distinct from each other because claims 1-8 and 10-12 of US 11,668,470 reads into and therefore anticipates the pending claims 21-23, 25-28, and 32-35 as shown in Table 1 below. Claims 37-40 under examination recite “cooking appliance” related limitations (see below), which would have been well-known auxiliary component of the claimed heating elements and would have been obvious to incorporate the heating element into the cooking appliance for household use.
