Office Action

§103 §DP
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 . Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claim 1 is provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claim 6 of copending Application No. 18/240,967. There is no secondary reference as the reference claim is narrower than the rejected claim 1 of the current application. This is a provisional nonstatutory double patenting rejection. Current Application Reference Application#18/240,967 Claim 1: A system for charging a battery comprising: a switch [1]; a transformer in operable communication with the switch [2]; and a processor in communication with the switch [3] and in communication with a model of the transformer [4], the processor configured to execute instructions to control the switch to generate a sequence of pulses at the transformer to produce a shaped charge waveform [3] responsive to running the model to generate the shaped charge waveform [4]. Claim 6 (limitations of claim 1+claim 4+claim 6) A system for charging a battery comprising: a power supply circuit comprising a converter portion receiving a power signal, the power supply circuit further comprising a voltage booster portion; a storage capacitor in operable communication with an output of the booster portion of the power supply circuit, the storage capacitor and power supply circuit correcting for a power factor loss of the power signal during charging of an electrochemical device; and a combined direct current/direct current (DC/DC) converter and charge waveform shaping circuit to alter a DC signal from the booster portion to a shaped charge waveform for charging the electrochemical device. Claim 4: … wherein the combined DC/DC converter and charge waveform shaping circuit comprises: a transformer in operable communication with the power supply circuit to receive the power signal; a switch in operable communication with the transformer [1,2]; and a processor in communication with the switch and configured to execute instructions to control the switch to generate a sequence of pulses at the transformer to produce the shaped charge waveform [3]. Claim 6: … wherein the processor is in communication with a model of the transformer and further configured to control the switch responsive to running the model [4]. Claim 1 is provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claim 11 of copending Application No. 17/566,535. Although the claims at issue are not identical, they are not patentably distinct from each other because then reference claim is narrower than the currently pending claim of the current application This is a provisional nonstatutory double patenting rejection. Current Application Application#17/566,535 Claim 1: A system for charging a battery comprising: a switch [1]; a transformer in operable communication with the switch [2]; and a processor in communication with the switch and in communication with a model of the transformer [3], the processor configured to execute instructions to control the switch to generate a sequence of pulses at the transformer to produce a shaped charge waveform responsive to running the model to generate the shaped charge waveform [4]. Claim 11 (limitations of claim 1+ claim 11): Claim 1: A system for charging a battery comprising: a first switch [1]; a first inductive element in operable communication with the switch [2]; a second inductive element in operable communication with the first inductive element; and a processor in communication with the switch and in communication with a model [3], the processor configured to execute instructions to control the switch to generate a sequence of pulses at the first inductive element to produce a shaped charge waveform responsive to running the model to generate the shaped charge waveform [4], wherein the model comprises a model of the first inductive element, the second inductive element, and a battery. Claim 11: The system of claim 1 wherein the first inductive element is a part of a transformer [2]. 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. 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) 1-4, 6-13, 17-18 and 20-23 is/are rejected under 35 U.S.C. 103 as being unpatentable over HOSOTANI (US 2014/0368056 A1, hereinafter HOSOTANI) in view of DADRAS et al. (US 2017/0080814 A1, hereinafter DADRAS). PNG media_image1.png 608 840 media_image1.png Greyscale Regarding claim 1 (claim 1 is considered representative for limitation matching purposes), HOSOTANI discloses a system for charging a battery comprising: a switch (See Fig.1, Item#S1 and Par.77, disclose a switching element comprising a switch Q1); a transformer in operable communication with the switch (See Fig.1, disclose a primary coil Lp of power transmitting unit PSU and a secondary coil Ls of power receiving unit PRU, the two coils when placed close to one act as a transformer); and a processor in communication with the switch (See Fig.1 and Par.79, disclose a processor 10 for controlling the switch Q1), the processor configured to execute instructions to control the switch to generate a sequence of pulses at the transformer to produce a shaped charge waveform (See Fig. 1 and Par.107 disclose "By turning on/off the switching element Q1 through the control of the switching control circuit 10, an alternating current is flowed in the power transmitting coil Lp by the power transmitting unit-side alternating current generation circuit." Also Par.115 discloses "FIG. 2 is a diagram illustrating voltage and current waveforms at the corresponding portions in the power transmission system 111 shown in FIG. 1. Hereinafter, operations in the respective states of switching period will be described with reference to FIGS. 1 and 2." The waveform shown in FIG. 2 is interpreted to be a shaped charge waveform). However, HOSOTANI does not disclose the processor is in communication with a model of the transformer and responsive to running the model generates the shaped charge waveform. DADRAS discloses to a wireless battery charging system comprising a transformer (See Par.17, discloses "Loosely coupled coils that form a transformer are present in a variety of systems and applications. In the loosely coupled transformer, a first coil may act as a primary coil and a second coil may act as a secondary coil."

The impedance may be selected to maximize energy transferred from the transmit coil 40 to the receive coil 34. The impedance value may be selectable from control signals from one or more of the controllers."). HOSOTANI and DADRAS are analogous art in the field of wireless charging systems. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by of HOSOTANI with the teachings of DADRAS by adding the disclosed model to the processor to produce a shaped charge waveform responsive to the model of DADRAS for the benefit of improving the performance of the transformer (See DADRAS, Par.17, discloses “…accurate knowledge of the parameters is beneficial. A transformer parameter estimation system may provide an estimate of the parameters so that performance may be improved"). Regarding claim 2, HOSOTANI and DADRAS disclose the system of claim 1 as discussed above, wherein the switch is operably coupled with a power supply (See HOSOTANI, Fig.1 and Par.76, discloses an input power source Vi in an input section of the power transmitting unit PSU) and the processor is further configured to execute the sequence of pulses and adjust the sequence of pulses to produce the shaped waveform (See Par.34, discloses “the power transmitting unit-side alternating current generation circuit be configured to control transmission power by deforming a waveform of a resonance current with respect to an ideal sine curve using PWM (pulse width modulation) in which a time ratio is controlled by turning on/off a switching circuit at a fixed switching frequency.") and DADRAS (as applied to claim 1 rejection) discloses a processor executing charging according to the model (See Par.52, discloses " Based on the parameters identified for the transformer model, the selectable impedance may be selected for one or both of the transmit coil 40 and the receive coil 34. The impedance may be selected to maximize energy transferred from the transmit coil 40 to the receive coil 34. The impedance value may be selectable from control signals from one or more of the controllers."). HOSOTANI and DADRAS are analogous art in the field of wireless charging systems. It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by HOSOTANI by adjusting the control circuit with one that produces a shaped charge waveform produce pulses according to the model like DADRAS for the benefit of improving the performance of the transformer, as disclosed by DADRAS (See Par.17, discloses "accurate knowledge of the parameters is beneficial. A transformer parameter estimation system may provide an estimate of the parameters so that performance may be improved."). Regarding claim 3, HOSOTANI and DADRAS disclose the system of claim 1 as discussed above, and DADRAS further discloses the model comprises a configurable inductance value and a configurable resistance value (See Par.32, discloses "The primary-side circuit 102 of the transformer model 100 includes a series connection of a primary resistance, R1 106, a primary inductance, L 1 108, and a secondary current dependent voltage generator 110.

The test voltage may be a pulsed voltage or square wave at a predetermined frequency to excite the system to allow for improved parameter identification. The identification may be performed until the error between the estimated current and actual measured current is less than a predetermined error. The test voltage may also be applied for a predetermined duration. A magnitude of the test voltage may be less than a typical charging voltage magnitude." NOTE: By applying a test voltage for a duration, multiple measurements on the signal are taken, until the current estimated by the model matches the observed current. The "identification" in context is the model parameters, aka the resistance and inductance, so the model is correcting those parameters until the model current matches the observed current.). Regarding claim 4, HOSOTANI and DADRAS disclose the system of claim 3 as discussed above, wherein the first measurement is a first current or a first voltage, the second measurement is a second current or a second voltage, and the respective first intended measurement is a first intended current or first intended voltage and the respective second intended measurement is a second intended current or a second intended voltage (See DADRAS, Par.53 discloses " For the identification to take place, a test voltage may be applied to the transmit coil 40.

The secondary-side circuit 104 includes a series connection of a secondary resistance, R2 112, a secondary inductance, L2 114, and a primary current dependent voltage generator 116."). Regarding claim 11, HOSOTANI discloses a system for charging a battery (See Fig 1, and Par.198 disclose "load Ro of the second power transmitting/receiving unit PSU/PRU2 has a rechargeable battery and a charging circuit thereof.") comprising: a first switch (See Fig.1, Item#S1 and Par.77, disclose a switching element comprising a switch Q1), a first inductor in operable communication with the first switch (See Fig.1 and Par.77 disclose an inductor Lp in communication with the switch Q1); and a processor in communication with the switch (See Fig 1, Item#10 and Par.79 disclose "… the power transmitting unit PSU is provided with a switching control circuit 1O for controlling the switching element Q1."), the processor configured to execute instructions to control the switch to generate a sequence of pulses at the transformer to produce a shaped charge waveform ((See Fig. 1 and Par.107 disclose "By turning on/off the switching element Q1 through the control of the switching control circuit 10, an alternating current is flowed in the power transmitting coil Lp by the power transmitting unit-side alternating current generation circuit."

Hereinafter, operations in the respective states of switching period will be described with reference to FIGS. 1 and 2." The waveform shown in FIG. 2 is interpreted to be a shaped charge waveform). However, HOSOTANI does not disclose a processor in communication with a model including the first inductor or produces a shaped charge waveform responsive to running the model to generate the shaped charge waveform. DADRAS discloses to a wireless battery charging system comprising a transformer (See Par.17, discloses "Loosely coupled coils that form a transformer are present in a variety of systems and applications. In the loosely coupled transformer, a first coil may act as a primary coil and a second coil may act as a secondary coil." Also Par.23, discloses "The EVSE 38 may have one or more transmit coils 40 that are configured to be placed in proximity to one or more receive coils 34 of the vehicle 12.") and a processor Par.62, discloses "The processes, methods, or algorithms disclosed herein can be deliverable to/implemented by a processing device, controller, or computer, which can include any existing programmable electronic control unit or dedicated electronic control unit.") in communication with a model of the transformer (See Fig.2, Item#130 and Par.47-48, disclose "The Kalman filter described may be implemented in the EVSE controller 130. The Kalman filter operates to reduce an error between a measured transmit coil current (Y) and an estimated transmit coil current (FT*{circumflex over (T)}) that is derived from a model defined by the parameters.") and produces a shaped charge waveform responsive to running the model to generate the shaped charge waveform (See Par.52, discloses “ Based on the parameters identified for the transformer model, the selectable impedance may be selected for one or both of the transmit coil 40 and the receive coil 34. The impedance may be selected to maximize energy transferred from the transmit coil 40 to the receive coil 34. The impedance value may be selectable from control signals from one or more of the controllers."). HOSOTANI and DADRAS are analogous art in the field of wireless charging systems. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by of HOSOTANI with the teachings of DADRAS by adding the disclosed model to the processor to produce a shaped charge waveform responsive to the model of DADRAS for the benefit of improving the performance of the transformer (See DADRAS, Par.17, discloses “…accurate knowledge of the parameters is beneficial. A transformer parameter estimation system may provide an estimate of the parameters so that performance may be improved"). Regarding claim 12, HOSOTANI and DADRAS disclose the system of claim 11 as discussed above, wherein the first inductor comprises a first side of the wireless interface (See HOSOTANI, Par.77 discloses "The power transmitting unit PSU includes ... a switching circuit S1 that is connected with the power transmitting coil Lp", Also Par.152 discloses, " .. the power can be efficiently transmitted by wireless… "), the system further comprising a second inductor comprising a second side of a wireless interface, the first inductor and the second inductor operably forming a transformer when proximately positioned relatively (See HOSOTANI, Fig.1 and Par.78 disclose "The power receiving unit PRU includes: a power receiving coil Ls"), the first inductor and the second inductor operably forming a transformer when proximately positioned relatively (See HOSOTANI, Par.5 discloses "a power transmitting coil and a power receiving coil together act as an insulation transformer''. The transmitting coil Lp and the receiving coil Ls when placed close to one another form a transformer).

In this example, a push-pull circuit is configured including two FETs Q1 and Q2 on the power transmitting unit side. With this, a larger amount of power can be supplied in comparison with a case where the ·push-pull configuration is made using one FET. Further, since the two FETs Q1 and Q2 alternately carry out switching operation, an electromagnetic field resonance coupling circuit can be formed equivalently twice the frequency."). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by HOSOTANI and DADRAS as applied to claim 11 with the further teachings of HOSOTANI by adding a second inductor to the first side of the wireless interface for the benefit of allowing a larger amount of power to be transferred to the wireless power receiving device.

The identification may be performed until the error between the estimated current and actual measured current is less than a predetermined error. The test voltage may also be applied for a predetermined duration. A magnitude of the test voltage may be less than a typical charging voltage magnitude." The examiner explains that by applying a test voltage for a duration, multiple measurements on the signal are taken, until the current estimated by the model matches the observed current. The "identification" in context is the model parameters, aka the resistance and inductance, so the model is correcting those parameters until the model current matches the observed current).

The secondary-side circuit 104 includes a series connection of a secondary resistance, R2 112, a secondary inductance, L2 114, and a primary current dependent voltage generator 116."). Regarding claim 23, HOSOTANI and DADRAS disclose the system of claim 11 as discussed above, However, HOSOTANI and DADRAS do not disclose wherein the system comprising a second switch in electrical communication with the first switch on a common node in electrical communication with the first inductor HOSOTANI further discloses a system comprising a second switch in electrical communication with the first switch on a common node in electrical communication with the first inductor (See FIG.116 and Par.190, disclose multiple switches Q1-Q4 share common nodes in communication with inductor Lp). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by HOSOTANI and DADRAS as applied to claim 11 with the further teachings of HOSOTANI by replacing the single switch on the transmission side with the plurality of switches for the benefit of transmitting a larger amount of power (See HOSOTANI, Par.190). Claim(s) 5 and 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over HOSOTANI in view of DADRAS and in further view of VON NOVAK et al. (US 2010/0277003 A1, hereinafter VON NOVAK). Regarding claims 5 and 19 (claim 5 is considered representative for limitation matching purposes), HOSOTANI and DADRAS disclose the system of claim 1 as discussed above. However, HOSOTANI and DADRAS do not disclose wherein that the processor comprises a microcontroller. VON NOVAK, drawn to wireless power systems with a transformer model, discloses a processor that comprises a microcontroller (See Par.108 discloses "A general purpose processor may be a microprocessor, but in the alternative, the processor may be any conventional processor, controller, microcontroller, or state machine."). HOSOTANI, DADRAS and VON NOVAK are analogous art in the field of wireless power transmitters. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by HOSOTANI and DADRAS such that the processor of HOSOANI and DADRAS be a microcontroller as disclosed by VON NOVAK for the known benefit of having a compact size. Claim(s) 14-16 is/are rejected under 35 U.S.C. 103 as being unpatentable over HOSOTANI in view of DADRAS and in further view of MILLER et al. (US 2016/0001662 A1, hereinafter MILLER). Regarding claim 14, HOSOTANI and DADRAS disclose the system of claim 11 as discussed above, further comprising a DC power source (See HOSOTANI, Fig.1, Item:Vi and Par 76). However, HOSOTANI and DADRAS do not disclose further comprising an AC to DC converter operably coupled with the wireless interface and converting an AC signal from the wireless interface to a DC signal operably applied to the first switch. MILLER discloses a wireless power transmitting device comprising a wireless interface (See Fig.4, Item: primary pad comprising a wireless power transmitting inductor L1), further comprising an AC to DC converter operably coupled with the wireless interface and converting an AC signal from the wireless interface to a DC signal (See Fig.4, Item” Active Front end “AFE” and Par.15, disclose AFE receives AC from AC power source Uac and delivers a unipolar “DC” voltage) operably applied to the first switch (HOSOTANI, Fig.1 discloses DC is provided to the switch Q1 of Figure 1 and the combination of HOSOTANI, DADRAS and MILLER would provide the output of the AC to DC converter to the switch). HOSOTANI, DADRAS and MILLER are analogous art since they all deal with wireless charging. It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by HOSOTANI and DADRAS with the teachings of MILLER by adding an AC to DC converter for the benefit of extending the wireless charger operating time by using a mains power supply comprising an AC source. Regarding claim 15, HOSOTANI, DADRAS and MILLER disclose the system of claim 14 as discussed above, wherein the wireless interface receives AC power from a power source (See HOSOTANI, Fig.1, and Par.107, disclose the transmitting coil Lp receives AC by controlling switch Q1 to change DC into AC). Regarding claim 16, HOSOTANI, DADRAS and MILLER disclose the system of claim 14 as discussed above wherein the wireless interface receives power from a DC source (See HOSOTANI, Fig.1, in this case the interface is interpreted to be coil Lp+Q1) and includes a DC to AC converter to provide an AC signal to a transformer of the wireless interface (See HOSOTANI, Fig.1, Item#Q1 and Item#10, disclose a switch which is controlled to change the DC input Vi into AC and apply it to the wireless interface Lp).
