Office Action

§103
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 . 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. Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the: communication terminals recited in the claims; communication lines recited in the claims; third IC recited in Claim 9-11 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Objections Claims 2-16 are objected because of the following informalities: The claims recite “IC” and the acronym needs to be spell out the first time. It appears IC stands from integrated circuit. Appropriate correction is required. 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. Claims 1-8, 15 & 17-18 are rejected under 35 U.S.C. 103 as being unpatentable over Chen (US 2015/0366266) in view of Wietfeldt (US 2017/0075843). Regarding Claim 1, Chen discloses an apparatus for an aerosol generation device, the apparatus comprising: a connector [ground & H1 pin or AT pin] to which a heater [S1] that heats an aerosol source [H1] by consuming electric power supplied from a power supply [power supply] is connected (FIG. 1-2, ¶ [0044-0046]; The heater strip S1 provides heat for atomization. The power supply provides power for the electronic cigarette); a controller [100] that includes a first communication terminal [terminal of VDD] and a second communication terminal [AT] for serial communication and that controls supply of the electric power from the power supply [power supply] to the heater [S1] (FIG. 1-2, ¶ [0045]; the heater strip S1 is connected to the AT pin of the control chip 100, the liquid storage H1 is connected to the NCT pin of the control chip 100, the indicator light LED1 is connected to the LED pin of the control chip 100.

Regarding Claim 3, Chen in view of Wietfeldt disclose the apparatus according to claim 1 [see rejected Claim 1], Wietfeldt discloses wherein the controller is configured to operate a plurality of modes, and any mode, among the plurality of modes, in which the controller communicates with the first IC is the same as any mode, among the plurality of modes, in which the controller communicates with the second IC (Claim 51; during an arbitration phase, asserting from a gateway a most urgent priority value to win arbitration. Claim 53-54; logical ones and zeroes). It would have been obvious to one of ordinary skilled in the art before the effective filling date of the claimed invention to incorporate Wietfeldt’s teachings into Chen’s controller for the same reasoning as in claim 1. Regarding Claim 4, Chen in view of Wietfeldt disclose the apparatus according to claim 1 [see rejected Claim 1], Wietfeldt discloses wherein the controller is configured to periodically communicate with the second IC (Claim 2; activating a second IC coupled to the bus). It would have been obvious to one of ordinary skilled in the art before the effective filling date of the claimed invention to incorporate Wietfeldt’s teachings into Chen’s controller for the same reasoning as in claim 1. Regarding Claim 5, Chen in view of Wietfeldt disclose the apparatus according to claim 1 [see rejected Claim 1], Wietfeldt discloses wherein a number of modes, among a plurality of modes, in which the controller communicates with the second IC is larger than a number of modes, among the plurality of modes, in which the controller does not communicate with the second IC (Claim 1; activating a first integrated circuit (IC) coupled to a bus; registering first nodes associated with the first IC with a first gateway). It would have been obvious to one of ordinary skilled in the art before the effective filling date of the claimed invention to incorporate Wietfeldt’s teachings into Chen’s controller for the same reasoning as in claim 1. Regarding Claim 6, Chen in view of Wietfeldt disclose the apparatus according to claim 5 [see rejected Claim 5], Wietfeldt discloses wherein the plurality of modes include a sleep mode in which a transition to any other mode is allowed, the sleep mode being a mode in which power consumption is smaller than in any other mode, and the controller is configured to communicate with the second IC through the second communication line in all modes among the plurality of modes except the sleep mode (¶ [0005]; Communication between nodes may be further complicated by nodes operating according to different sleep/wake rules set by different standards. Clock signals may be sent over each bus, which may increase difficulty in complying with the EMI emissions limits or the EMC standards. Still further, if an IC is coupled to multiple buses, the IC may have different interfaces, one for each coupling). It would have been obvious to one of ordinary skilled in the art before the effective filling date of the claimed invention to incorporate Wietfeldt’s teachings into Chen’s controller for the same reasoning as in claim 1. Regarding Claim 7, Chen in view of Wietfeldt disclose the apparatus according to claim 5 [see rejected Claim 5], Wietfeldt discloses wherein the plurality of modes include a sleep mode in which a transition to any other mode is allowed and an error mode in which charging of the power supply is at least temporarily prohibited, the sleep mode being a mode in which power consumption is smaller than in any other mode (¶ [0005]; Communication between nodes may be further complicated by nodes operating according to different sleep/wake rules set by different standards. Clock signals may be sent over each bus, which may increase difficulty in complying with the EMI emissions limits or the EMC standards. Still further, if an IC is coupled to multiple buses, the IC may have different interfaces, one for each coupling), and the controller communicates with the second IC through the second communication line in all modes among the plurality of modes except the sleep mode and the error mode (Claim 52; detecting an error … and responsive to detecting the error, determining the system reset is needed). It would have been obvious to one of ordinary skilled in the art before the effective filling date of the claimed invention to incorporate Wietfeldt’s teachings into Chen’s controller for the same reasoning as in claim 1. Regarding Claim 8, Chen in view of Wietfeldt disclose the apparatus according to claim 5 [see rejected Claim 5], Wietfeldt discloses wherein the controller communicates with the second IC in all modes included in the plurality of modes (Claim 2; activating a second IC coupled to the bus).
