Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed in parent Application No. KR10-2022-0128203 filed on 10/06/2022 and KR10-2022-0149696 filed on 11/10/2022.
Information Disclosure Statement
Information Disclosure Statements (IDS) filed on 04/03/2025 and 02/11/2026 were considered.
Claims 1-20 are pending for examination.
Specification
The disclosure is objected to because of the following informalities: Paragraph [0064] there are two different items “second coil” and second sensor” sharing the same reference designator (322).
Appropriate correction is required.
Applicant' s cooperation is requested in correcting any errors of which applicant may become aware in the specification.
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 1-17 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 1, lines 17-18 recite “cause the foldable electronic device to”. The term “foldable” or related concept can not be found in the disclosure. Therefore, the limitation is insufficiently disclosed.
Regarding claims 2-17, the claims are rejected due to the rejection of claim 1 above.
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 1-20 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.
Regarding independent claim 1, lines 17-18 recite “control circuitry, connected with the second coil, configured to:
supply a current to the second coil to generate an induced current in the first coil, and
based on the current and the induced current, supply power from an external electronic device to the battery or transmit power from the battery to the external electronic device”.
The recitation is unclear because according to the disclosure, a coil with variable capacitor is a tunable resonant coil (first coil) and a coil that is connecting with the control circuitry is a feeder coil (second coil). Since the limitation requires the “control circuitry, connected with the second coil, configured to:
supply a current to the second coil to generate an induced current in the first coil” which indicating the electronic device is in transmitting mode. Therefore, it is unclear how the electronic device “supply power from an external electronic device to the battery” while in the transmitting mode. For the examination purpose, the limitation will be construed as “based on the current and the induced current,
Regarding independent claim 18, the claim is similarly rejected as claim 1 above.
Regarding dependent claims 2-17 and 19-20, the claims are rejected due to the rejection of claims 1 and 18 above.

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the combination of KIM, Cooper and LEE to incorporate the teaching of ASANO and provide a first temperature sensor and a second temperature sensor as the sensor, and wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to identify, based on sensing values of the first temperature sensor and the second temperature sensor, a position of the external electronic device. Doing so would allow identifying position of the external device since it is well-known in the art that insufficient power transfer would cause the coils temperature increase when a position of the coil of the external device is not well aligned with the coils of the electronic device.
Regarding claim 11, the combination of KIM, Cooper, LEE and ASANO discloses the electronic device of claim 10 above, KIM discloses the electronic device comprising a housing forming an exterior of the electronic device.

wherein the second temperature sensor is disposed between a second lateral surface of the housing opposite to the first lateral surface and the second coil. However, since the Applicant does not disclose the criticality of the aforementioned displacement of the temperature sensors, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention that the placement of ASANO would be equivalent and perform the same expected result to the claim invention since it would be able to determine the position of the external device.
Regarding claim 12, the combination of KIM, Cooper, LEE and ASANO discloses the electronic device of claim 10 above, the combination of KIM, Cooper, LEE and ASANO does not explicitly disclose wherein the first temperature sensor is disposed at an outer perimeter of the second coil, and wherein the second temperature sensor is surrounded by the first coil and the second coil.

Regarding claim 13, the combination of KIM, Cooper and LEE discloses the electronic device of claim 1 above, KIM discloses the sensor. The combination of KIM, Cooper and LEE does not disclose the sensor is disposed between the first coil and the second coil.

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the combination of KIM, Cooper and LEE to incorporate the teaching of ASANO and provide the sensor is disposed between the first coil and the second coil. Doing so would allow sensing temperature of both coils at the same time.

Regarding claim 15, the combination of KIM, Cooper and LEE discloses the electronic device of claim 1 above, in one of the embodiment Cooper discloses the first coil and the second coil are in different planes (Fig. 1a).

Doing so would allow minimizing area of the coils for maximizing the amount of power transfer.
The combination of KIM, Cooper and LEE does not explicitly disclose when the battery is viewed from above, the second coil partially overlaps with a portion including a periphery of the first coil. CHOI discloses a wireless power transfer system having a second coil partially overlaps with a portion including a periphery of a first coil (Fig. 7F, second coil 762 partially overlaps first coil 761). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the combination of KIM, Cooper and LEE to incorporate the teaching of CHOI and have geometry of the first coil different than geometry of the second coil to have when the battery is viewed from above, the second coil partially overlaps with a portion including a periphery of the first coil. Doing so would allow maximizing wireless power transfer with a limited area based on a requirement of the first and a second coil.
