Office Action

§103 §112
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 . Priority Receipt is acknowledged of papers submitted under 35 U.S.C. 119(a)-(d), which papers have been placed of record in the file. Information Disclosure Statement The information disclosure statements (IDSs) submitted on 03/16/2023, 01/06/2025 and 02/19/2025 are acknowledged by the examiner. 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 1-9 and 11 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 1 recites “---Values without respective units”. It is unclear how the values of Ls, Rs and D can be described without units. In addition, this recitation contradicts with the limitations recited in Claim 1, lines 6-8 where the units for Ls, Rs and D are described. Claim 11 recites “---Values without respective units”. It is unclear how the values of Ls, Rs and D can be described without units. In addition, this limitation contradicts with the limitations recited in Claim 11, lines 7-9 where the units for Ls, Rs and D are described. 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. Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Kook (US 2009/0261778) in view of Machine translation of KR. 1020190136447, hereinafter 447’. As to claim 10, Kook discloses in figure 10, a wireless charging device [see figure 10[, which comprises a coil unit [see figure 10, element 516] comprising a conductive wire; a magnetic unit [magnetic plate (503)] disposed on the coil unit; and a shield unit [shield plate 515] disposed on the magnetic unit, Kook does not disclose explicit, wherein the distance between the coil unit and the magnetic unit is 0.5 mm to 7 mm, and at a frequency of 85 kHz, the Q factor of the wireless charging device is 300 to 1,000, the inductance measured through the coil unit is 30 μH to 200 μH, and the resistance measured through the coil unit is 40 mΩ to 200 mΩ. 447’ discloses in figure 1, wherein the distance between the coil unit and the magnetic unit is [there is a distance between the Goil and the magnetic unit] and at a frequency of [128KHz] the Q factor of the wireless charging device is [20 or more] , the inductance measured through the coil unit is [11.6 or more], and the resistance measured through the coil unit is [ 100; see also pages 18 and 22] It would have been obvious to a person having ordinary skill in the art at the time the invention was made to modify charging coils and Q factor parameters of Kook’s as taught by 447’ in order to increase charging efficiency. Neither Kook nor 447’ discloses explicitly, wherein the distance between the coil unit and the magnetic unit is 0.5 mm to 7 mm, and at a frequency of 85 kHz, the Q factor of the wireless charging device is 300 to 1,000, the inductance measured through the coil unit is 30 μH to 200 μH, and the resistance measured through the coil unit is 40 mΩ to 200 mΩ.. It would have been obvious to one having ordinary skill in the art at the time the invention was made to use appropriate values of Q factor, inductance, and resistors in Kook’s apparatus, since it has been held that discovering an optimum value of a result effective variable involves only routine s-kill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980). Allowable Subject Matter Claims 1-9 and 11 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
