Claim Rejections - 35 USC § 112
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 4-5 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.
Regarding claim 4 and its dependent, the specification does not provide sufficient written description to support the claimed recitation “wherein each of the protrusion portions includes: a pair of main protrusion portions traversing between the heat discharge openings adjacent to each other …; and a sub-protrusion portion disposed between the pair of the main protrusion portions …” because:
i) claim 4 defines that each protrusion portion includes a pair of main protrusion portions and a sub-protrusion portion disposed between the pair of main protrusion portions, i.e., the claimed sub-protrusion portion is disposed between each main protrusion portion of the pair of main protrusion portions;
ii) according to Figs. 1-2 and [0054-0055], the specification discloses each protrusion portion 300 in Fig. 1 comprising a pair of main protrusion portions 320s in Fig. 2 and a sub-protrusion portion 340 in Fig. 2, wherein the sub-protrusion portion 340 of a first protrusion portion in annotated Fig. 2 is disposed between the pair of main protrusion portion 320s of the first protrusion portion in annotated Fig. 2 and the pair of main protrusion portion 320s of a second protrusion portion in annotated Fig. 2, i.e., the disclosed sub-protrusion portion disposed between two of the pair of main protrusion portions that belongs to two different protrusion portions; moreover, the specification at [0015] merely states the claim limitation of claim 4;

iii) it is noted, “There is a presumption that an adequate written description of the claimed invention is present when the application is filed. In re Wertheim, 541 F.2d 257, 263, 191 USPQ 90, 97 (CCPA 1976) (“[W]e are of the opinion that the PTO has the initial burden of presenting evidence or reasons why persons skilled in the art would not recognize in the disclosure a description of the invention defined by the claims.”). However, as discussed in subsection I, supra, issues of adequate written description may arise even for original claims, for example, when an aspect of the claimed invention has not been described with sufficient particularity such that one skilled in the art would recognize that the inventor had possession of the claimed invention at the time of filing. The claimed invention as a whole may not be adequately described if the claims require an essential or critical feature which is not adequately described in the specification and which is not conventional or known in the art”, MPEP 2163 I(A), and “The written description requirement is not necessarily met when the claim language appears in ipsis verbis in the specification. “Even if a claim is supported by the specification, the language of the specification, to the extent possible, must describe the claimed invention so that one skilled in the art can recognize what is claimed. The appearance of mere indistinct words in a specification or a claim, even an original claim, does not necessarily satisfy that requirement.”Enzo Biochem, Inc. v. Gen-Probe, Inc., 323 F.3d 956, 968, 63 USPQ2d 1609, 1616 (Fed. Cir. 2002”, MPEP 2163.03V;
iv) therefore, the specification does not provide sufficient written description for one of ordinary skill in the art to recognize that the inventor had possession of the claimed invention as claimed in claim 4, and thus, claim 4 and its dependent is rejected as lacking written description.
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.

Regarding claim 4 and its dependent,
I. recitations “each of the protrusion portions includes: …”, “a pair of main protrusion portions traversing between the heat discharge openings adjacent to each other”, “a sub-protrusion portion disposed between the pair of the main protrusion portions” renders claim 4 indefinite because:
i) term “the protrusion portions” lack antecedent basis and it is unclear whether said term means a) the previously claimed one or more protrusion portions in claim 1 is a plurality of protrusion portions and each of the plurality of protrusion portions includes …; or b) each of a plurality of protrusion portions includes … and the previously claimed one or more protrusion portions in claim 1 belongs to the plurality of protrusion portions;

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 (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.
Claims 1-8 are rejected under 35 U.S.C. 103 as being unpatentable over HWANG 20210259064 in view of HWANGBO 20180376541.
Regarding claim 1, HWANG teaches the invention as claimed: A base plate structure (comprising 210 in Fig. 16) facilitating heat discharge (by providing cooling air flowing through gaps G1 and G2, see Figs. 15 and 17-18 and [0198-0199]) of a heating coil (WC in Figs. 16-18 and 23-24), comprising:
a circular base plate (210 in Fig. 16), wherein at least one or more sensors (temperature sensor 400, [0222]) are disposed in a center sensor portion (where 203 is, see Figs. 16-18);
one or more unit mounting groove portions (a plurality of groove portions that each has a respective ferrite 211 coupled to, only one groove portion is marked in annotated Fig. 16 for clarity, also see 18 and [0211 and 0213]), each of which is defined by a closed partition wall (the wall forms each groove portion as a closed square shape which is the unfilled part of the groove portion in annotated Fig. 16) protruding from a lower side (where a lower surface of plate 210 that contacts the ferrites 211 is, see annotated Fig. 18) of the base plate (210), wherein the unit mounting groove portions are repeatedly disposed as an annulus (the plurality of groove portions are repeatedly disposed as an annulus, see Fig. 16) with respect to the center sensor portion (where 203 is) and a ferrite core (a respective ferrite core 211) is coupled to the unit mounting groove portions (a respective groove portion, see Fig. 16);
one or more protrusion portions (a plurality of protrusion portions that each comprises a pair of main protrusion portions formed by a plurality of ribs positioned on a pair of support beams 207s in Figs. 16-18 and a sub-protrusion portion formed by a plurality of ribs positioned on one support beam 209 in Figs. 16-18, only one protrusion portion is marked in annotated Fig. 23 for clarification) protruding from an upper side (where an upper surface of plate 210 that contacts the heating coil WC is, see annotated Fig. 18) of the base plate (210) such that the heating coil (the portion of the heating coil WC located radially inner as marked in annotated Fig. 18) wound in the upper side (the portion of the upper side located radially inner as marked in annotated Fig. 18) of the base plate (210) is spaced apart (by the rib(s) that separate the upper side as the portion located radially inner and the portion located radially outer) from the upper side (the portion of the upper side located radially outer as marked in annotated Fig. 18) of the base plate (210); and
one or more heat discharge openings (a heat discharge opening 212, see Figs. 16-17 and [0160]) provided in a bottom side of the unit mounting groove portions (interpreted as the lower side of base plate, and the heat exchange opening 212 form at the lower side of the base plate 210 where heating coils WC is disposed, see Fig. 16).

HWANG does not teach wherein at least one or more hall effect sensors are disposed in said center sensor portion.
However, HWANGBO teaches a sensor (20, Fig. 4) that is a combined unit of temperature sensor (402) and hall effect sensor (comprising sensing coil 44 and magnetic core 404 and per [0052-0054] the sensing coil 44 receiving a current from controller, if the cooling vessel is not placed or is non-inductive, the inductance value L of sensing coil 44 does not change, and if the cooling vessel is placed and is inductive, the inductance value L of sensing coil 44 changes, such that per [0045] the placement and material of the vessel is detected, which indicate the sensing coiling 44 is part of a hall effect sensor).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to modify HWANG with HWANGBO’s sensor combined temperature sensor and hall effect sensor, such that
wherein at least one or more hall effect sensors are disposed in a center sensor portion (the modification is to replace HWANG’s temperature sensor with HWANGBO’s sensor combined temperature sensor and hall effect sensor) in order to accurately and quickly identify the type of cooking vessel that is able to be heated via induction while consuming less power (HWANGBO, [0008-0009]).
Regarding claim 2, HWANG further teaches one or more heating
coil coupling portions (a plurality of heat coil coupling portions, which is the upper surface of each of the plurality of support beams 207 where the heating coil WC is placed on, see illustration in annotated Fig. 23), each of which is provided between the unit mounting groove portions adjacent to each other (because each support beam 207 is provided between two adjacent support beams 209s where the unit mounting groove portions formed, best seen in Fig. 16), wherein the heating coil coupling portions are repeatedly disposed in a radial direction with respect to the center sensor portion (interpreted as the plurality of heating coil coupling portions, i.e., the plurality of upper surface of the plurality of support beams 207s where heating coil WC is placed, see annotated Fig. 23, are disposed in a circumferential direction, i.e., see Figs. 16 and 23, and each of the plurality of heating coil coupling portions respectively extends in a radial direction, i.e., each of said plurality of upper surface of the plurality of support beams 207s respectively extends in a radial direction from where 203 is to where 205 is, see Figs. 16 and 23) so that the heating coil (WC) is fixed in the upper side (where the upper surface of plate 210 that contacts the heating coil WC is, see annotated Fig. 18 in claim 1) of the base plate (210).

Regarding claim 3, HWANG further teaches wherein the heat discharge openings (the one heat change opening 212 claimed in claim 1 is a plurality of heat change openings 212) are repeatedly disposed as an annulus (best seen in Fig. 16) with respect to the center sensor portion (where 203 is, see Fig. 16) and cause an upper space (where gap 213a in Fig. 17 and gap 213b in Fig. 18 are) of the base plate (210) and a lower space (where fan 90 in Fig. 17 is) of the base plate (210) to vertically communicate with each other (in order for the cooling air provided by fan 90 to flow through gaps G1, 213a, 213b, and G2, see Figs. 17-18).
Regarding claim 4, HWANG further teaches wherein each of the protrusion portions (each of the plurality of protrusion portions) includes:
a pair of main protrusion portions (the pair of main protrusion portions as marked in annotated Fig. 23 comprising the plurality of ribs disposed on the pair of support beams 207s) traversing between the heat discharge openings adjacent to (according to Cambridge dictionary, adjacent means next/near to) each other (a first heat exchange opening and a second heat exchange opening near to the first heat exchanger as marked in annotated Fig. 23, also see Fig. 16 for the full layout) and extending from the center sensor portion (where 203 is, see Fig. 16) to a periphery portion (where edge 205 is, see Fig. 16) of the base plate (210) in a radial direction (from where 203 is to where 205 is, see Fig. 16); and
a sub-protrusion portion (the sub-protrusion portion as marked in annotated Fig. 23 comprising the plurality of ribs disposed on the support beam 209) disposed between the pair of the main protrusion portions (see annotated Fig. 23) and extending from a point (annotated Fig. 23) spaced from each heat discharge opening (the first heat exchange opening and the second heat exchange opening, see annotated Fig. 23) to the periphery portion (where edge 205 is, see Fig. 16) in the radial direction (from where 203 is to where 205 is, see Fig. 16).
