Office Action

§103 §112
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 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 01/19/2026 has been entered. The previous Claim Objections are withdrawn in light of applicant's amendment to the claims. Claim Interpretations - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term "means" or "step" or a term used as a substitute for "means" that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term "means" or "step" or the generic placeholder is modified by functional language, typically, but not always linked by the transition word "for" (e.g., "means for") or another linking word or phrase, such as "configured to" or "so that"; and (C) the term "means" or "step" or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word "means" (or "step") in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word "means" (or "step") in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre- AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word "means" (or "step") are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word "means" (or "step") are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. A. Claim limitation “heating elements” has/have been interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because it uses/they use generic placeholder “elements” coupled with functional language “heating” and without reciting sufficient structure to achieve the function. Furthermore, the generic placeholder is not preceded by a structural modifier. Since the claim limitation(s) invokes 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, claims 1 and 13 has/have been interpreted to cover the corresponding structure described in the specification that achieves the claimed function, and equivalents thereof. A review of the specification shows that the following appears to be the corresponding structure described in the specification for the 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph limitation: Under FIG. 1, [0032], heating elements 104a-f. B. Claim limitation “control elements” has/have been interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because it uses/they use generic placeholder “elements” coupled with functional language “control” and without reciting sufficient structure to achieve the function. Furthermore, the generic placeholder is not preceded by a structural modifier. Since the claim limitation(s) invokes 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, claims 1 and 13 has/have been interpreted to cover the corresponding structure described in the specification that achieves the claimed function, and equivalents thereof. A review of the specification shows that the following appears to be the corresponding structure described in the specification for the 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph limitation: Under FIG. 1, [0032], control elements 106a-f, and [0036] the control elements 106a-f are knobs that are adjustable. C. Claim limitation “light elements” has/have been interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because it uses/they use generic placeholder “elements” coupled with functional language “light” and without reciting sufficient structure to achieve the function. Furthermore, the generic placeholder is not preceded by a structural modifier. Since the claim limitation(s) invokes 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, claims 1 and 13 has/have been interpreted to cover the corresponding structure described in the specification that achieves the claimed function, and equivalents thereof. A review of the specification shows that the following appears to be the corresponding structure described in the specification for the 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph limitation: Under FIG. 1, [0032], light elements 102a-f. If applicant wishes to provide further explanation or dispute the examiner’s interpretation of the corresponding structure, applicant must identify the corresponding structure with reference to the specification by page and line number, and to the drawing, if any, by reference characters in response to this Office action. If applicant does not intend to have the claim limitation(s) treated under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may amend the claim(s) so that it/they will clearly not invoke 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, or present a sufficient showing that the claim recites/recite sufficient structure, material, or acts for performing the claimed function to preclude application of 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. For more information, see MPEP § 2173 et seq. and Supplementary Examination Guidelines for Determining Compliance With 35 U.S.C. 112 and for Treatment of Related Issues in Patent Applications, 76 FR 7162, 7167 (Feb. 9, 2011). 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. Claims 3-4 and 12-21 are rejected under 35 U.S.C. 112(b) 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 pre-AIA the applicant regards as the invention. Claim 3 recites the limitation “a power level” in line 5 rendering the claim indefinite. It is unclear what the relation between this “a power level” and a plurality of power levels mentioned in claim 1 line 4 are? Appropriate correction/ clarification is required. Claim 4 recites the limitation “a power level” in line 4 rendering the claim indefinite. It is unclear what the relation between this “a power level” and a power level mentioned in claim 3 line 5 are? Appropriate correction/ clarification is required. Claim 12 recites the limitation “wherein the one or more light elements are configured to be visible to a user of the cooktop system when one or more items of cookware are positioned above the one or more heating elements of the cooktop system” is unclear in context, because “one or more items of cookware” are an unclaimed part of the invention and this “one or more items of cookware” can have a variety of shapes and sizes and might block “the one or more light elements” and may not be visible to a user as claimed. Therefore, the limitation of claim 12 are indefinite (See MPEP 2173.05(b) II). Appropriate correction/ clarification is required. Claim 13 recites the limitation “the at least one or more heating elements” in line 14. There is insufficient antecedent basis for this limitation in the claim. Claim 15 recites the limitation “a power level” in line 1 rendering the claim indefinite. It is unclear what the relation between this “a power level” and a power level mentioned in claim 13 line 15 are? Appropriate correction/ clarification is required. Claim 16 recites the limitation “the one of more of the heating elements” in line 10. There is insufficient antecedent basis for this limitation in the claim. Claim 17 recites the limitation “the one of more of the heating elements” in line 9. There is insufficient antecedent basis for this limitation in the claim. Claim 18 recites the limitation “the one or more of the one or more control elements” in line 9. There is insufficient antecedent basis for this limitation in the claim. Claim 18 recites the limitation “the one of more of the heating elements” in last line. There is insufficient antecedent basis for this limitation in the claim. Claim 21 recites the limitation “wherein the one or more light elements are configured to be visible to a user of the cooktop system when one or more items of cookware are positioned above the one or more heating elements of the cooktop system” is unclear in context, because “one or more items of cookware” are an unclaimed part of the invention and this “one or more items of cookware” can have a variety of shapes and sizes and might block “the one or more light elements” and may not be visible to a user as claimed. Therefore, the limitation of claim 12 are indefinite (See MPEP 2173.05(b) II). Appropriate correction/ clarification is required. The rest of the claims are also been rejected because each claim depends on a rejected claim. 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 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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1-8 and 10-21 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hilbey (EP 1 020 686 A1) in view of SAPORETTI et al. (US 2020/0128630 A1). Regarding Independent Claim 1, Hilbey disclose a cooktop system (see Fig 1), comprising: a cooktop including one or more heating elements spaced apart along a cooktop surface (cooking surface has four burners 3-6 spaced apart along a cooktop surface, [0010], Fig 1) and one or more control elements (four control means 7-10, [0011], Fig 1) that control power delivered to each of the one or more heating elements, the one or more control elements are adjustable to provide a plurality of power levels to each of the one or more heating elements (each of which can control the power level delivered by one of the four burners 3-6, [0011]), the one or more control elements are positioned along a front surface of the cooktop (four control means 7-10 are positioned along a front surface of the cooktop, Fig 1) and the one or more heating elements are spaced apart along the cooktop surface between the front surface and a rear surface of the cooktop opposite the front surface (burners 3-6 are spaced apart along the cooktop surface between the front surface and a rear surface of the cooktop opposite the front surface, Fig 1); and one or more light elements of the cooktop surface (indicator lights 11-14, [0013], Fig 1), each light element of the one or more light elements spaced apart along the cooktop surface from the one or more control elements with respect to a corresponding one of the one or more heating elements (each indicator light 11-14 spaced apart along the cooktop surface from the one or more control elements 7-10 with respect to a corresponding one of the one or more heating elements, Figs 1-2) and between the corresponding one of the one or more heating elements and the front surface of the cooktop (indicator light 11-14 between the corresponding one of the four burners 3-6 and the front surface of the cooktop, Fig 1), the one or more light elements include a plurality of power indication stages that correspond to the plurality of power levels (apparent speed of movement of the light points can be used to visualize the level of power control of the focus, [0022], Fig 3); wherein, responsive to an adjustment of at least one of the one or more control elements to select a power level from the plurality of power levels of at least one of the one or more heating elements, the cooktop system is configured to activate a corresponding one of the one or more light elements positioned at the corresponding one of the one or more heating elements to illuminate a power indication stage of the plurality of power indication stages that corresponds to the power level of the corresponding one of the one or more heating elements (a one-second increment period is used to visualize a low power control level and a shorter period to visualize a higher power control level, [0022], Fig 3). Hilbey discloses the invention as claimed and as discussed above; except does not disclose one or more light elements of a cooktop surface (taught already by Hilbey); and each light element of the one or more light elements positioned at and centered visually with respect to a corresponding one of the one or more heating elements (“the one or more heating elements” taught already by Hilbey); SAPORETTI et al. further teach a cooktop system (see Title), and one or more light elements (light source 11, [0035], Figs 1-2. Note: “one or more light elements” taught by Hilbey already) of a cooktop surface (a cooktop surface including top plate 3 and a support portion 5, [0034-0035], Fig 1), each light element of the one or more light elements (Note: “each light element of the one or more light elements” taught by Hilbey already) positioned at and centered visually with respect to a corresponding one of the one or more heating elements (light source 11 positioned at and centered visually with respect to a corresponding heating element- coil 2, [0034], Fig 2. Note: “the one or more heating elements” taught by Hilbey already); Therefore, it would have been obvious before the effective filling date of the claimed invention to one of ordinary skill in the art to add Hilbey with SAPORETTI et al.’s further teaching of one or more light elements of a cooktop surface; each light element of the one or more light elements positioned at and centered visually with respect to a corresponding one of the one or more heating elements; because SAPORETTI et al. teach, in Para. [0005], of providing an excellent light indicators with enhanced information content in order to improve the usability of the induction hob. Claim 2, wherein the one or more light elements are light bars (light bar 20, [0015], Fig 2, Hilbey). Claim 3, wherein the plurality of power indication stages (Note: “the plurality of power indication stages” taught by Hilbey already) incrementally and symmetrically extend further outwardly towards a right side and a left side of the cooktop from a center portion of each of the one or more light elements (light guide 13.1 may extend form an inner portion of the induction coil 2, [0042], Fig 2, SAPORETTI et al.) responsive to adjustments at the one or more control elements (Note: “to adjustments at the one or more control elements” taught by Hilbey already) to increase a power level supplied to one or more of the one or more heating elements (each of which can control the power level delivered by one of the four burners 3-6, [0011], Hilbey), wherein the center portion of each of the light elements is aligned with a center of each of the corresponding one of the one or more heating elements (see Fig 2, SAPORETTI et al.).

Hilbey); and adjusting the power indication stage of the one or more light elements (Note: “the adjusting the power indication stage of the light element” taught by Hilbey already) includes incrementally growing an illuminated area of the one or more light elements outwardly from a first side of the one or more light elements (light guide 13.1… form an inner portion of the induction coil 2, [0042], Fig 2, SAPORETTI et al.) responsive to adjustments at one or more of the one or more control elements (Note: “the light element responsive to adjustments at the one or more control elements” taught by Hilbey already) to increase the power level supplied to the one or more of the heating elements (each of which can control the power level delivered by one of the four burners 3-6, [0011], Hilbey). Claim 18, wherein the adjustment of the power level decreases the power level of one of the activated heating elements (four control means 7-10, each of which can control the power level delivered by one of the four burners 3-6, [0011]. Hilbey); and the adjusting the power indication stage of the light element (Note: “the adjusting the power indication stage of the light element” taught by Hilbey already) includes incrementally retracting an illuminated area of the light element inwardly towards a first side of the light element and away from a second side of each of the light elements (light guide 13.1… form an inner portion of the induction coil 2, [0042], Fig 2, SAPORETTI et al.) responsive to adjustments at the one or more control elements to decrease the power level supplied to one or more of the heating elements (each of which can control the power level delivered by one of the four burners 3-6, [0011], Hilbey) Claim 19, wherein the one or more control elements comprises a plurality of control elements (four control means 7-10, [0011], Fig 1, Hilbey), wherein each of the one or more light elements is individually responsive to one of the plurality of control elements (four indicator lights 11 to 14 are located on the hob… the second end of which is located in the vicinity of the control panel close to the control means with which it is associated, [0013], Figs 1 and 3, Hilbey). Claim 20, wherein the one or more heating elements are induction heating elements (an induction hob, [0018], Hilbey). Claim 21, wherein the one or more light elements are configured to be visible to a user of cooktop system when one or more items of cookware are positioned above the one or more heating elements of the cooktop system (lights visible by transparency under a transparent hearth plate 23 made for example of glass or glass-ceramic… each indicator light 11 to 14 is produced by means of a light bar 20, [0014-0015], Figs 1-3, Hilbey). Claim 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hilbey (EP 1 020 686 A1) in view of SAPORETTI et al. (US 2020/0128630 A1) as applied to claim 8 and further in view of Millett (US 2017/0027378 A1). Regarding Claim 9, Hilbey in view of SAPORETTI et al. teach the invention as claimed and as discussed above; except does not disclose Claim 9. Millett further teaches a cooktop system and apparatus (a heating appliance 16, [0023], Fig 1) including light element (reference numeral 10 generally refers to an indicial light module to) and Claim 9, wherein each one of the one or more light elements (Note: “the one or more light elements” taught by Hilbey already) includes a timer (a control 160 for operating the indicial light module 10 can include a timing function, [0033], Fig 1). Therefore, it would have been obvious before the effective filling date of the claimed invention to one of ordinary skill in the art to add Hilbey in view of SAPORETTI et al. with Millett’s further teaching of Claim 9; because Millett teaches, in P 2 Col 1 line 40-50, of providing an excellent control panel to provide user with illuminated lights of the actual cool down condition of the cooktop for operational safety purpose. Response to Arguments Applicant’s arguments with respect to Claims 1-21 have been considered but are moot in view of the new ground(s) of rejection presented in this Office Action as stated above.
