Office Action

§102 §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 certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statements (IDS) submitted on 09/02/2022, 08/14/2024, and 08/15/2025 were filed. The submissions are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner. Claim Objections Claim 17 objected to because of the following informalities: Claim 17 begins with the article “An.” Examiner suggests amending claim 17 to begin with the article “The.” Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claims 16-18 are rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claim 16 depends on claim 1 but does not further limit claim 1. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

The voltage PVIN or both are controlled to manage the energy supplied to the coil 21. Since the current of the coil 21 is almost the same as the current of the power amplifier 41, the current of the power amplifier 41 can be detected and used as the current of the coil 21.”; Both the current and the voltage of the coil are known, power is inherently know.). Regarding claim 7, Hwang teaches the apparatus as appears above (see the rejection of claim 1), and Hwang teaches wherein the control arrangement (Fig. 4 #42 controller) is configured to adjust the first DC voltage output by the voltage regulator (Fig. 4 #44 DC-DC converter) based on a determined temperature of the susceptor arrangement (Page 4 para. 3 ---" The controller 42 controls the switching waveform of the power amplifier 41 by using the temperature of the coil 21, the voltage of the coil 21, the current of the coil 21, or the output of the DC-DC converter 44.”).

The coil 21 may be equivalent to the inductor L. The resonator capacitor 400 is connected to the coil 21 to form the resonator 40. The resonant capacitor 400 forms the resonator 40 together with the coil 21 to determine the resonant frequency.”). Regarding claim 11, Hwang teaches the apparatus as appears above (see the rejection of claim 10), and Hwang teaches wherein the switching arrangement (Fig. 4 #411-412 switches) is configured to alternate between a first state and a second state to cause the varying current through the inductive element (Fig. 4 #21 coil), and wherein the switching arrangement (Fig. 4 #411-412 switches) is configured to alternate between the first state and the second state in response to voltage oscillations within the resonant circuit (Fig. 4 #21 coil and #400 resonant capacitor) (Page 4 para. 1 ---" The switches M1 and M2 411 and 412 alternate on and off and have a reverse phase waveform.

For example, the controller 42 generates a switching waveform control signal for increasing the temperature of the sensed coil 21 when the temperature of the coil 21 is lower than a preset value and provides it to the power amplifier 41, and lowers it when it is higher than the preset value. A switching waveform control signal for generating may be generated and provided to the power amplifier 41.”).

Claim Rejections - 35 USC § 103 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. 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. Claim(s) 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hwang et al (KR 20200009993 A) as applied to claim 17, in view of Reevell et al (US 2019/0380391). Regarding claim 18, Hwang teaches the aerosol generating device as appears above (see the rejection of claim 17), but does not teach wherein the susceptor arrangement is provided in a component separate from, and configured to releasably engage with, the aerosol provision device. Nonetheless, Reevell in the same field of endeavor being aerosol generating devices teaches wherein the susceptor arrangement )Fig. 2 #20 susceptor) is provided in a component separate from, and configured to releasably engage with, the aerosol provision device (The susceptor is shown to be separate from and releasably engage with the aerosol provision device.). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the aerosol generating device of Hwang by incorporating the susceptor arrangement as taught by Reevell for the benefit of preparation for further use or for cleaning.
